# Executive Associate Project Manager's Summary (J. Shank, BU)

The computing effort for this quarter continued to be focused on running
production for the Computing System Commissioning (CSC) exercises which
started in earnest last quarter. The main software development was the
release of 12.0.3, the software needed for the currently running
production for CSC. There were key meetings this quarter on Tier 2
facilities ([T2 meeting at Harvard August,
2006](http://indico.cern.ch/conferenceDisplay.py?confId=4897)) and on
the Distributed Data Management (DDM) system ([DDM workshop at BNL,
Sept. 2006)](http://indico.cern.ch/conferenceDisplay.py?confId=6495)).
These meetings allowed us to focus on ramping up our facilities to
handle the increasing demands of the CSC exercises and handle the
growing amount of simulated data that is distributed around the world.
We continue to debug/harden the ATLAS DDM and work on easing DDM
deployment. Throughout this quarter our Tier1 and Tier 2 sites were
filled with CSC production running.

**Note #1**  Release 12.0.x continues to be validated, expected to be
complete by end of 2006 and used for CSC simulation production

**Srini Rajagopalan (Brookhaven National Laboratory)**

The software effort during this quarter continues to be preparation for
the upcoming Computing System Commissioning (CSC). Release 12.0.0 was
released this quarter. The validation of this production release and
addition of necessary functionalities continues. Release 12.0.3 came out
on September 22, 2006 and included an extensively validated simulation
and digitization packages. The intent is to use this production release
for the simulation production for CSC.

Release 12.0.4 is expected in November 2006, and will include updated
calibration constants needed to take into account new material and
misalignment effects in 12.0.3 simulation. The highest priority is
therefore production of calibration samples which will quickly be
analyzed and updated constants made available in 12.0.4. 12.0.4 will
then be used for reconstruction of the simulation production and
subsequent CSC analysis studies.

Release 13.0.0 is expected to come out in February 2007 and Release 14
in June 2007. A validated release 14 will be deployed for the initial
(900 GeV) LHC running.

PANDA, a major U.S. deliverable, is successfully being used for the CSC
production. The U.S. is also increasing its focus on Distributed Data
Management adding pressure to the ATLAS computing management to ensure
that a robust system is developed and deployed in time for the CSC
exercises. Alexei Klimentov (BNL) has now been appointed to focus on the
U.S. Distributed Data Management effort.

The analysis support centers continue to mature with one-week analysis
jamborees being held or planned at the three analysis support centers
(ANL, BNL, LBNL).

**Note #1**  we implemented a prototype plugin mgr in Gaudi, still based
on Gaudi DLL mechanism and the new Configurables. This will be put in
production in release 13. It may be replaced in the future by a
reflex-based scheme.

**Note #2**  started work on StoreGate access.

**Note #3**  Two CS summer students at LBL delivered a framework to
access the PropertyRepository as their project work. Focus now is on

new-style job configuration: Job-level properties, ToolHandle,
ServiceHandle (possibly DataObjectHandle), migrate all core examples to
configurables, document migration procedure (basic documentation
exists).

**Note #4**  awaits history persistency.

**Note #5**  some progress with framework tool but still no real-life
test of the functionality. This may come with TDAQ \"Large scale test\"
scheduled for next spring

**Note #6**  port completed in time. Unfortunately while Gaudi and
Control compile and run fine in 64-bit machines, athena reconstruction
jobs are much too big to run on lxplus. We should try to address this
problem after release 13

**Note #7**  prototype in c++ available. During prototype development it
appeared obvious that a python implementation is probably easier to
write and maintain. This will be investigated till December and a final
implementation will go in release 13

**Note #8**  automatically seed generator from the run/evt# stream ID,
evaluate new random engine, possibly allow to choose random engine

**Joe Boudreau (University of Pittsburgh)**

Nearly all of the effort in this quarter went into preparing the CSC
exercise. This included a large amount of database administration,
debugging, declashing, and revising the geometry, particularly the
geometry of the LAr (and particularly in the endcap and the crack).

In addition we made a large effort to revise, more or less completely,
the readout geometry of the LAr. This will dramatically reduce the
memory consumption, we think, and will also provide a much tighter
coupling between readout geometry and simulation geometry, and a badly
needed cleanup in the LAR detector description.

This is nearly done. The first layer is complete for 12.3.0. The second
layer is also nearly ready and will go in immediately following the
release of 12.3.0. We can foresee a little debugging thereafter. And
following that we will make sure that this is useful not only for full
ATLAS but also for the beam test configurations, and also for the
digitization and reconstruction of those configurations.

**Note #1**  Joe will do this over the holiday break.

**Joe Boudreau (University of Pittsburgh)**

The v-atlas program was revised: it is now a python script and not a
shell script that writes python scripts. Sounds minor but the impact of
this small change on maintainability is impressive.

A full revision of the tracks display was carried out. Users can click
on tracks and see their hits light up, as well as the surfaces. Muon
tracks are displayed. And other nice features added to the interface.
Very well received in the tracking group.

**2.2.3 Data Management**

**David Malon (ANL)**

As ATLAS approaches full-chain testing, more and more components require
integration with upstream components, and hence are more subject to
delays outside of U.S. Research Program control. Event-level selections,
for example, require trigger decision information that is not yet
available to event tag builders. Luminosity information essential to
commissioning an offline cross-section calculation support
infrastructure, and quality and detector status summary information
necessary to support sample selection, are also not yet available.

As international ATLAS begins to think more concretely about
data-taking, a number of task forces are being commissioned. A metadata
task force is underway, as is a streaming study group, and an Analysis
Object Data

(AOD) format task force will begin work in October 2006. U.S. Research
Program participation in all of these is strong. These initiatives will
doubtless provide important input to the ATLAS event store and data
management efforts, but one of the consequences is that delivery of some
components must be delayed until recommendations are formulated. The
U.S. ATLAS Research Program should anticipate a significant last-minute
influx of requirements in its 2007 effort planning.

**Note #1**  December 2005: Agreement with ATLAS software management is
to postpone this milestone until it is specifically requested or
required by physics.

June 2006: This work will be deferred until after the ATLAS streaming
study group makes its recommendations.

September 2006: International ATLAS streaming study group has not yet
made recommendations. In the interim, POOL placement control
capabilities have been extended.

**Note #2**  December 2005: A limited version will be introduced into
early 2006 releases, but a more general strategy awaits the outcome of a
spring 2006 event store developers workshop.

September 2006: Transaction context control will require changes to the
LCG POOL code base. These changes are not expected before early 2007.

**Note #3**  31 March 2006: Partially complete; completion pending
documentation of Release 12 infrastructure, which was delayed by
international ATLAS.

September 2006: Twiki-based user-level documentation was improved after
Release 12. Documentation to enhance usability remains a priority,
though, and a new documentation-related milestone will be introduced
soon.

**Note #1**  30 September 2005: Actual delivery may be later in the
quarter because the prototype requires new versions of LCG dictionary
software that will not be delivered to us until later in the quarter.

December 2005: This milestone must be delayed until some time after the
corresponding control framework history infrastructure is in place.

September 2006: The corresponding control framework support has been
descoped from Release 13, so event store support cannot be provided
until a subsequent release.

**Note #2**  31 March 2006: Delayed pending outcome of May 2006 Physics
Analysis Tools workshop

September 2006: Descoped from core and event data model plans for
Release 13, and hence from event store work as well.

**Note #3**  31 March 2006: Delayed pending proposed ATLAS metadata task
force

September 2006: International ATLAS metadata task force has begun work,
but has provided no guidance or recommendations yet.

**Note #4**  31 March 2006: Delayed pending proposed ATLAS metadata task
force

September 2006: International ATLAS metadata task force has begun work,
but has provided no guidance or recommendations yet.

**Note #5**  September 2006: Implementation requires changes to
bytestream I/O services provided by TDAQ. These will not be available
until after the next TDAQ software release (currently proposed for
November 2006).

**Note #6**  September 2006: Extensions sufficient to support luminosity
block identification in streams tests have been added, but \"final\"
work awaits TDAQ work on evolution of the ATLAS event header.

**Note #7**  September 2006: While event-store-specific components are
ready, delays in preparation of data samples may cause some reduction in
the scale of this prototype.

**Torre Wenaus (Brookhaven National Laboratory)**

PanDA based distributed analysis tools were routinely available and in
use during the quarter. Stable analysis pilot delivery was achieved
following the improvements of the previous quarter. About 20 users have
made use of pathena for PanDA based analysis during the last month; a
similar number have run over 100 jobs with the system, and 7 have used
it for more than 1000 jobs. The system was used in another Physics
Jamboree at BNL in August, and a tutorial on PanDA for analysis was
given at the ATLAS software week in September.

The multi-tasking pilot supporting concurrent running of production and
analysis jobs from one pilot was deployed in production during the
quarter, but its concurrent analysis job feature remained under test and
not yet activated for general use. Capability was extended to support
event collection analysis and long jobs. Work began to extend PanDA
deployment for analysis to the LCG, based on a new scheduler/pilot
system designed for broad deployment (see discussion of TestPilot in
PanDA section 2.2.4.2).

**2.2.4.3 Production Support**

**Torre Wenaus (Brookhaven National Laboratory)**

Production support continued to be an integral part of the production
system, distributed analysis and distributed data management efforts,
with all participants in those programs contributing to production
support. During the quarter Alexei Klimentov took on the new role of US
ATLAS DDM Operations Coordinator, responsible for overall coordination
of DDM activities in US ATLAS. Alexei is the ATLAS DDM Operations
Coordinator, so our operations are well integrated with ATLAS. No
specific production support milestones were called out in this quarter,
it is an ongoing activity.

U.S. ATLAS continued to make major contributions to production support
at the ATLAS level in both distributed data management operations and in
production task definition.

An important bugfix was introduced into the ATLAS interface to Pythia.
The Pythia bug was affecting the generation of the underlying event.
Assistance was provided to other Generator package developers which
resulted in the release of a new Generator interface for Matchig. The
ATLAS interfaces of Sherpa were updated to the latest version (1.0.8).
This version migration was needed for the ATLAS CSC event generation
production. Assistance was provided to the Winhac developers during a
very detailed validation process of the ATLAS-Winhac interface.
Extensive interactions with the ATLAS user community took place,
supporting them on their physics analysis tasks.

V. Jain began working on 01-Aug-06. Jain as a replacement for D. Best.
Jain will continue to work on b-tagging but in the context of the Event
Filter using wrapped versions of the normal tracking code. Jain spent
his time learning to use the new Tracking code within Athena and
learning how the event filter is working. Jain will work on using Athena
Aware n-tuples to study and optimize the b-tagging algorithms.

W. Lampl presently provides services for filling the COOL database with
reconstruction parameter updates and conditions data for the calorimeter
test-beams. The main activities here still are the FCal2004, and the H6
and H8 combined test-beam runs (2005). The versioning of the hadronic
calibration constants using this database technology is also still
ongoing, in close collaboration with MPI. He has also continued his work
on calorimeter EDM improvements, in collaboration with P. Loch, and he
is now contributing to the development of the object navigation code in
the Athena data model, here again in collaboration with Loch and S.
Binet (LBNL). As usual he still maintains his role as the principal
consultant regarding electron/photon reconstruction for ATLAS, and he
deals with demands from general ATLAS requiring his expertise in this
subject as well.

For the period of July-September, Moyse has been working on more issues
with the performance of our persistency technology, and has been
involved in discussions about ways to improve this both within and
outside the EMB. He has also been trying to fix remaining bugs for the
12.0.x releases, in particular with regards to the EDM/Geometry and
Truth. Moyse has also introduced the Muon Reconstruction runtime
package, to enable the Muon community greater control over Muon
reconstruction (previously it was being managed centrally).

The SMU Monitoring Software effort has progressed in three components
during the July-September period. The upgrade of the Gatherer for the
tdaq-01-06 release was completed by Haleh Hadavand. Initial work to make
further improvements for the upcoming tdaq-01-06 release was begun by
Peter Renkel and Hadavand. Substantial efforts to integrate the TDAQ
software into the LAr monitoring effort were pursued, resulting in
successful use with several new tools, and also for early cosmics data.
A revamped online shifter panel was designed and implemented by two SMU
students under the guidance of Hadavand. The online monitoring setup for
LAr was also rationalized and committed to CVS. Lastly, the design
document for the Data Quality Monitoring Framework was finalized and
submitted to the Monitoring Working group and Data Quality coordinator
for review. Some implementations and design elements concerning
algorithms have been begun.

**Alexander Undrus (Brookhaven National Laboratory)**

In this quarter the experimental ATLAS nightly builds were started on
SLC4 32 and 64-bit platforms at CERN. In these nightly jobs the distcc
program distributed the release compilation task to the cluster of
computers. As a result the release compilation time was reduced by about
factor of 3. For the standard SLC3 platform four branches of the
nightlies were run (bugfix, development, experimental, and for trigger
studies). The experimental distribution kit builds were created for the
bugfix nightlies. These kits were further downloaded by the pacman tool
and verified by the Kit Validation test suite. As a result the full
chain of ATLAS software distribution undergoes tests in the nightly
builds framework. Many improvements were made to NICOS, ATLAS nightly
release tool, such as automatic removal of excessive static libraries
from the releases, automatic notifications in cases when AFS nightly
volumes are filled close to the capacity, better web pages design. The
number of nightly integration tests performed in the ATN testing
framework reached 97 (30% more as compared with the previous quarter).
The scripts allowing to run an ATN test in users local areas were added
to ATN. At BNL new stable ATLAS software and DB releases were promptly
installed, usually in one to two days after CERN installation. As well
as the following mirrors were available at BNL: ATLAS CVS code
repository, ATLAS pacman code distribution cache, ATLAS nightly builds
for the development and bugfix branches. The LXR server, alxr.U.S.
ATLAS.bnl.gov, provided the collaboration-wide service for the fast
searches in ATLAS software codes. The indexes for the latest stable
releases were made available.

Participants had the opportunity to work in subgroups organized
according to physics analysis and/or detector performance interests.
Feedback from the participants was excellent.

## 2.3 Facilities {#facilities .unnumbered}

**2.3 Subsystem Manager\'s Summary**

**Razvan Popescu (Brookhaven National Laboratory)**

Tier1 and Tier2 Facilities:

The Tier1 staff grew by 3 engineers, expected to work on dCache, grid
services development and system monitoring. 20TB of high performance,
high reliability, disk storage system had been released to operations in
support of mission critical filesystem; the capacity upgrade of the main
computing farm is complete, bringing the installed capacity to 1400 job
slots and 525TB of distributed storage. WAN/OPN private L2 circuits are
operational and had demonstrated production level services during the SC
exercises (200MB/sec sustained incoming traffic from T0).

The Midwest T2 completed the upgrade of the site, reaching an installed
capacity of 154k SI2K and 65 TB dCache distributed storage. DQ2
packaging and installation scripts were delivered for use on all T2
installations. The 10G service to Starlight is operational. The staff
continued the support efforts for PanDA productions and DQ2 operations,
while continuing final preparations for deployment of the two new MWT2
clusters at IU and UC.

The Northeast Tier 2 center has been in production operation for the
past quarter, the work done has been dominated by PanDA production.
International ATLAS users have also used the facility, at a lower
priority level. The staff worked with the ATLAS SIT team in expanding
the system of software distribution mirrors to the UM Tier 2 site in the
US and the RAL Tier 1 site in the UK. NE T2 had participated in ATLAS
coordinated DDM tests transferring data between T1\<-\>T2.

The new UTA SWT2 cluster began running production jobs on July 6th. The
long delay was due to infrastructure problems (power supply) and
hardware problems (IBRIX file system). Currently, there are 3 clusters
participating in managed CSC production: the old DPCC shared cluster
with 100 CPUs, the OU_SWT2 cluster with 84 CPUs and the new UTA_SWT2
cluster providing 304 CPUs. A total of 40TB of storage is available,
over the three installations. The DPCC cluster has also been made
available for analysis jobs.

The ATLAS Great Lakes Tier2 (AGLT2) has joined US ATLAS as a Tier2
starting September 1, 2006. Michigan State has been focusing on required
renovations to their server room. Current bids are in hand for
installing 28 ton A/C capacity which would accommodate about 14 racks of
equipment.

The University of Michigan has been focused on providing access to 59
dual processor Opteron nodes as our first 6 month Tier2 contribution.
The DQ2 server has been installed on a 64 bit server, which is the first
time this platform has been used for a production server. Michigan has
spent a significant amount of time debugging PanDA related issue for our
configuration. The AGLT2 should have 118 jobs slots validated and ready
for use by US ATLAS sometime in October.

The Western T2 at SLAC joined U.S. ATLAS in September 2006. The
installation of the first Tier-2 hardware at SLAC awaits major
electrical work that is planned for early December 2006. SLAC is already
offering batch services to ATLAS via OSG, using hardware whose primary
role is to serve BaBar. The ATLAS usage in September was around 250 CPU
hours per day. Over 2.5TB of dedicated ATLAS storage has been set up,
using storage that will eventually be returned to BaBar when storage
purchased with Tier-2 funds is installed.

Networking:

The LHC-OPN (T0-T1 Networking) met in Utrecht, Netherlands on September
22, 2006 to continue its work. During this meeting the working groups
were reorganized. The Monitoring group (led by S. McKee, U.S. ATLAS) was
deemed to have completed its work and a new group, led by Joe Metzger
from ESNet, on \"network instrumentation\" has been established. This
new working group will look at the next level of tools and installations
required for the production networking environment.

The relevant network research projects have all progressed. Terapaths
has deployed network management software at BNL and Michigan and is
expanding into production with \$30K/year per Tier2 (excluding SLAC) for
the next two years. UltraLight is preparing new kernels and data
transport applications focused on developing high-performance use of 10+
Gbit/sec networks. It is also continuing to develop a software stack for
broader deployment based upon agents and VINCI services. OSCARS has been
working closely with Terapaths, USNet, DRAGON, CHEETAH and others on
interoperability.

The Grid Tools and Services effort focused on:

a\) Programming for U.S. ATLAS PanDA executor

\- Development of the JobScheduler in collaboration with Xin Zhao

\- Development of a module to provide reliable and robust file movement
from the execution directories to the local SE and file registration in
the DQ2 server (DQ2ProdClient2.py)

\- Packaging of the PanDA packages

b\) Troubleshooting and support of U.S. ATLAS production activity

\- DQ2 operation (cleanup, troubleshooting)

\- Condor upgrade to 6.7.20 through ROCKS

c\) U.S. ATLAS Tier2 Data Service activity (this activity involves a
joint group from U.S. ATLAS Midwest Tier2 and Argonne National Lab). The
goals of the activity are the design, prototyping and packaging of a
service that could be deployed at ATLAS Tier2s and would include the
following functionalities:

\- Provide users the ability to access the Tier2\'s DQ2 server.

\- Host or provide access to ATLAS specific database services, such as
TAG and possibly conditions (IOV and calibration) databases.

\- Provide a skimming service for Tier2-resident datasets through either
command line or web interfaces.

d\) Activity within the ATLAS worldwide collaboration

\- Involvement in the ATLAS ProdSys protocol maintenance

\- Involvement in the effort to define common ATLAS error codes returned
by the production system

\- Participation in the ATLAS monitoring effort (FZK-CERN).

e\) Grid activities (OSG and Interoperability efforts)

\- Participation in the Glue Schema v1.2 and v1.3 effort:

\- Experiments to integrate PanDA with ReSS resource selection

\- Participation in the OSG monitoring and information system activity

\- Participation in the CE storage activity within OSG to provide
guidance on how to use disk space from within the CE environment.

Grid Production:

We continued CSC production during this quarter. The primary focus was
validation of Release 12 \-- U.S. ATLAS continued to produce around 25%
of the total MC data produced in ATLAS, validating releases 12.0.0,
12.0.1 and 12.0.2.

**Saul Youssef (Boston University)**

The Northeast Tier 2 center
(http://atlas000.bu.edu/NETier2/wiki/index.php/Main_Page) has been in
production operation for the past quarter. Although we now have 27 ATLAS
collaborators with local accounts and the ability to submit batch jobs,
the work done has been dominated by PanDA production managed by the
production team. International ATLAS users have also used our facility
through usatlas3 at a low level - typically 1 batch job with a peak of
20. Short interruptions in availability have occurred for one PBS
problem and an expired host certificate. We have worked with the ATLAS
SIT team in expanding the system of software distribution mirrors to the
UM Tier 2 site in the US and the RAL Tier 1 site in the UK. We have
participated in ATLAS coordinated DDM tests transferring data from
T1\<-\>T2. A problem was revealed transferring large (\>2G) files which
is probably related to our DRM installation. We have worked with the
production team in re-organizing how the ATLAS releases are distributed
for PanDA production.

**Kaushik De (University of Texas at Arlington)**

The new UTA SWT2 cluster finally began running production jobs on July
6th. The long delay is due to infrastructure problems (power supply) and
hardware problems (IBRIX file system). The IBRIX problems are
continuing, limiting our ability to make full use of the cluster. We are
discussing the situation with Dell and IBRIX support. We expect a patch
soon.

Currently, we have 3 clusters participating in managed CSC production.
The old DPCC shared cluster has 100 CPU\'s. The OU_SWT2 cluster has 84
CPU\'s. And the new UTA_SWT2 cluster is providing 304 CPU\'s (holding a
few in reserve for testing). DPCC has 20TB available to ATLAS (out of
45TB). OU has 4TB, while UTA_SWT2 has 16 TB available.

The DPCC cluster is also available for analysis jobs. We are waiting for
DQ2 to become more stable before we increase DA activity - since not all
AOD files are available yet.

We have started soliciting vendor quotes for our next purchase. This
will add 100 TB of disk space, plus some CPU\'s. This cluster will
primarily be used for user analysis support.

We continue to hold bi-weekly video meetings of the Southwest Tier 2
analysis group. A new SUSY analysis sub-group has also started holding
weekly phone meetings.

**Shawn McKee (University of Michigan)**

The ATLAS Great Lakes Tier2 (AGLT2) has just joined US ATLAS as a Tier2
starting September 1, 2006. This is our first quarterly report and
includes details from both the Michigan and Michigan State sites.

Both Michigan and Michigan State sent representatives (Bob Ball, Chip
Brock, Shawn McKee, Tom Rockwell) to the August 18th Tier-2 meeting at
Harvard.

Michigan State has been focusing on required renovations to their server
room. Current bids are in hand for installing 28 ton capacity which
would accommodate 14 racks of hardware at 8kW per rack or less. The
Department of Physics and Astronomy has agreed to take over one of two
possible additional rooms adjacent to the current server room in order
to provide expansion capabilities. This has opened up possibilities
within the College of Natural Science and a second bid is in hand for a
possible staged installation of 50 tons of cooling to add flexibility
for continued T2/T3 growth as well as anticipated College needs. A
spring completion is still anticipated and additional temporary space
has been made available in the central campus HPC area for one more HEP
rack of computing, for a total of two which will allow MSU to continue
to move toward provisioning of a few test-bed AGL nodes

The University of Michigan has been focused on providing access to 59
dual processor Opteron nodes as our first 6 month Tier2 contribution.
The DQ2 server has been installed on an SLC V4.4 x86_64 bit server
(which is the first time this platform has been used for a production
server) by Shawn McKee. The gatekeeper has been operational and running
OSG V0.4.1 since the second week in September. We have edited the OSG
monitoring tools to provide a correct view for resources from our site.

Michigan has spent a significant amount of time debugging PanDA related
issue for our configuration. There seem to be many undocumented
requirements beyond having a working OSG install that we have to deal
with to create a fully operational PanDA-compatible site.

The AGLT2 should have 118 jobs slots validated and ready for use by US
ATLAS sometime in October.

Michigan\'s permanent Tier-2 space will be ready for occupancy by
November and we are planning the migration details.

Both Michigan and Michigan State sent representatives (Shawn McKee, Tom
Rockwell) to the DDM workshop which was held at BNL on September 26 and
27, 2006.

were reorganized. The Monitoring group (led by S. McKee, U.S. ATLAS) was
deemed to have completed its work and a new group, led by Joe Metzger
from ESNet, on \"network instrumentation\" has been established. This
new working group will look at the next level of tools and installations
required for the production networking environment.

At the Tier-2 meeting in Boston on August 18, 2006, the set of network
related items were reviewed briefly and updated. Details are available
at:
http://www.usatlas.bnl.gov/twiki/bin/view/Admins/Tier2Workshop17Aug06
and http://www.usatlas.bnl.gov/twiki/bin/view/Admins/TierTwoNetworking.
Some highlights include plans to produce and maintain network diagrams
for each Tier-2, the setup and operation of dedicated NDT servers and
longer term planning to deploy end-host agents to monitor and optimize
network performance for end-hosts.

The relevant network research projects have all progressed. Terapaths
has deployed network management software at BNL and Michigan and is
expanding into production with \$30K/year per Tier2 (excluding SLAC) for
the next two years. UltraLight is preparing new kernels and data
transport applications focused on developing high-performance use of 10+
Gbit/sec networks. It is also continuing to develop a software stack for
broader deployment based upon agents and VINCI services. OSCARS has been
working closely with Terapaths, USNet, DRAGON, CHEETAH and others on
interoperability. A meeting to discuss this and US LHCnet is planned for
sometime in October at FNAL.

Status of the NSF PIF (PLaNetS) and DOE SCiDAC (LHC-MI) proposals are
still pending.

**2.3.5 Grid Production**

**Kaushik De (University of Texas at Arlington)**

We continued CSC production during this quarter. The primary focus was
validation of Release 12. We also continued to run Release 11 samples
requested by physics groups.

U.S. ATLAS continued to produce around 25% of the total MC data produced
in ATLAS. Releases 12.0.0, 12.0.1 and 12.0.2 were validated. Hundreds of
software bugs were reported based on high volume grid production. Many
hundreds of tasks were completed, with each release (and repeated for
various transformation cache releases).

The shift team continues daily shifts (6 days/week). Yuri Smirnov is the
shift captain. Nurcan Ozturk, Mark Sosebee and Tomasz Wlodek are on the
shift team. Xin Zhao continues to maintain ATLAS software installations
on the grid. Pavel Nevski is in charge of job definitions (ATLAS-wide).

## 3.1 M&O Silicon {#mo-silicon .unnumbered}

##  {#section-2 .unnumbered}

**3.1 Subsystem Manager\'s Summary**

**Alex Grillo (UCSC)**

Pixel end-cap A was fully connected to the prototype service quarter
panel in preparation for the 10% system test, however, some problems
with cooling fittings were encountered and a sector outlet pipe was
damaged. A new pipe connection tool has been designed and it may be
necessary to replace the damaged sector. A determination will be made on
16-Oct. There have also been failures of some of the opto paks curing
opto board QC at CERN. This problem is still being investigated. A
tighter QC procedure has been instituted. It is likely that 20% of opto
boards may be rejected by the more rigorous QC. The production of spare
opto boards has been delayed pending a better understanding of this
failure mechanism. In spite of these delays, the overall Pixel
integration program is moving ahead and has gained one month on the
schedule that was laid out in July for just-in-time installation next
year.

The integrated Inner Detector Barrel (SCT plus TRT) was moved to the
ATLAS cavern and installed in the cryostat on 24-Aug. It was moved to it
final location (i.e. Z=0) on 28-Sep. Cable testing and installation is
proceeding just ahead of "when needed" for each section of barrel and
end-caps. Full readout testing of the barrel in-situ should commence
sometime in late January once installation is complete, with cosmic ray
tests to follow.

Spares ROD parts are ordered. It is expected that they will be delivered
by the end of the calendar year. ROD software upgrades are ongoing.

**3.1.1 Pixels**

**Maurice Garcia-Sciveres (Lawrence Berkeley Laboratory)**

Endcap A was fully connected to the prototype service quarter panel in
the 10% system test. However problems were encountered with the threads
of the cooling fittings, making it difficult to achieve good gas seals.
A sector outlet pipe was damaged during disconnection of a leaky
fitting. This has prompted a redesign of the pipe connection tooling.
Preparations are underway to disassemble the endcap at CERN and replace
the damaged sector, if needed. A determination if it is required will be
made after the sector is operated with full power load and cooling,
projected for the week of Oct. 16. Other components of the system test,
including cosmic trigger and full cable connectivity are in place.

Failures of some optical paks have been seen in opto board QC test at
CERN. An investigation to understand these root cause of these problems
is ongoing. Nevertheless a more rigorous QC has been developed and opto
boards that passed this QC will be loaded starting Oct. 22. The
production of spare opto boards has been led back to allow further time
to understand the failures. It is likely that 20% of opto boards may be
rejected by the more rigorous QC, which means that all the spares will
be used in the initial detector.

**Note #1**  The ID Barrel was again delayed due to other installation
conflicts but has now been positioned inside the cryostat and at its
final position. Present installation schedule has installation (i.e.
cables, pipes, fibers, etc.) complete mid to late Jan-07. Initial
electrical tests should be completed within 4-6 weeks after that.

**Alex Grillo (UCSC)**

The integrated Inner Detector Barrel (SCT plus TRT) was moved to the
ATLAS cavern and installed in the cryostat on 24-Aug. It was moved to it
final location (i.e. Z=0) on 28-Sep. Both moves were performed without
any known problems. Connection of cables and pipes for the TRT started
the next day, 29-Sep, with SCT connections expected to start the first
week of November.

Cable testing and installation is still proceeding. The Type-II and
Type-III cable installation was completed prior to the September
centering of the barrel. Also, the retrofit of PP3 units with extra
electrical insulation was completed. Some Type-IV cables are still to be
installed. However, all cables and power supplies associated with the
barrel will be installed prior to the end of October allowing testing of
the full chain with the dummy PP1s prior to connections being made to
the SCT barrel.

Continuity tests of barrel connections will be performed as each section
is cabled. Full readout testing of the barrel in-situ should commence
sometime in late January once installation is complete, with cosmic ray
tests to follow.

**3.2 Subsystem Manager\'s Summary**

**Harold Ogren (Indiana University)**

This was a milestone laden period for the TRT barrel. In June we
finished the SCT - TRT joint testing; In July we completed all final
preparation tests on the HV, active gas, cooling, electronic readout,
and DAQ; On August 24 the Inner Detector (TRT and SCT) was lowered into
the ATLAS experiment and inserted into the central cryostat; On
September 25 the cabling and piping outside the detector was completed
and the ID was positioned at the center of the cryostat ready for
connection to services and cabling of the front face electronics. This
will be completed in the month of October.

**3.2.1.1 TRT Pre-Operations**

**3.2.1.1.8 ID Integration**

**Rick Van Berg (University of Pennsylvania)**

During the July-Sept. period the Barrel TRT was readied for installation
and actually lowered into the pit and fixed in final position inside the
cryostat. Electronics cabling and testing is scheduled to start in early
Oct. after final connection and testing of the fluid services. Ben
LeGeyt was central in planning the in-pit installation and testing
program. He will lead the actual installation effort, aided by Godwin
Mayers, Mike Reilly, and Rick Van Berg.

Integration tests of the Barrel will be completed using specialized test
software with results written to the test data base. The main DAQ system
is independent and that code is being tested against the new back end
electronics (TTC, ROD, and Patch Panels) by Paul Keener and Mike Hance.
All new drivers for the new hardware have been developed and are now
fully compatible with the main ATLAS acquisition model. By mid Oct. we
hope to have at least a few 32\'nds of the installed Barrel under
continuous power and DAQ control as a DAQ development setup and, as more
backend electronics become available, as a full system test exercise in
preparation for commissioning and alignment.

Both the end caps (A & C) are now complete in an electronics sense
except for a few HV lines on EC-A. All electronics have been tested and
verified by Ole Rohne and Franck Martin. The SCT endcap C was integrated
with the TRT endcap in mid Sept, the A side endcaps should be integrated
with each other in early Oct. EC - C has been moved to the test area in
SR and preparations are underway for doing combined tests - including
cosmic rays - to verify both systems. Two minor repairs are still needed
on EC - A electronics. Godwin Mayers should complete those in mid Oct.

**Harold Ogren (Indiana University)**

During this period our activities focused on the cooling services.

Ogren was at CERN from May 15 until August 12. He assisted Kirill Egorov
with the design, prototype tests, procurement of parts, and assembly of
the cooling system test racks.

Egorov was in charge of the cooling system testing for the TRT. He
designed a monometer test panel that is permanently attached to each of
the four cooling rack stations near the experiment. They will allow us
to monitor the leak rates of the 32 input-output lines for the
Fluorinert cooling system of the TRT.

Egorov also was the principle technical contact for the TRT. He was
responsible for finding a repairing any gas or cooling leaks on the
manifolds during the testing phase prior to moving the ID. He also
assisted in the HV tests and electrical test procedures. A postdoctoral
physicist from Indiana University, Siva Subramania, also helped during
this period with the computer monitor.

## 3.3 M&O Liquid Argon {#mo-liquid-argon .unnumbered}

**3.3 Subsystem Manager\'s Summary**

**Ryszard Stroynowski (Southern Methodist University)**

During the summer, the barrel calorimeter was tested for shorts. About
30 shorts showed up after the cool-down. A burn-out of shorts has been
attempted by a discharge of large capacitors at the entrance to the
cathode readout. This is a cumbersome procedure requiring demounting of
the front-end readout and isolation of the supply voltage in the HV
feedthrough. The burnout attempts have been successful for some of the
problems in the presampler (front part of the calorimeter) but made no
difference for the remaining three sectors. Since many of the shorts
appeared at the bottom of the calorimeter, it was hypothesized that
these are due to dirt particles that floated in during Argon filling. To
test this, the cryostat was emptied and then refilled by condensation
only. This process cleared some of the shorts but not all of them. A
campaign to burn out the presampler shorts is planned for after the
magnet tests.

The commissioning of the readout electronics is slow, mostly due to
limited access and due to continuing problems with low voltage power
supplies. The electronics commissioning for the barrel is coming to the
end. About 15% of the boards required replacement of the components. The
commissioning of the endcap electronics progresses well but is limited
by the lack of the low voltage power supplies. Since there are just few
of them, for each crate the power supply has to be mounted and connected
and then moved to a different location. Most of the effort is shifting
to the commissioning of the system of crates, its interaction with the
back-end electronics and trigger.

The status of the low voltage power supplies became critical. MDI is
continuing to retrofit the produced modules at the rate of about 2 per
week, i.e., much slower than the promised 4/week. Unfortunately, the
lifetime of the retrofitted units appears to be rather short. Several
failed after the time of operations ranging from few days to few months.

The failure analyses provided by the company are generated with much
reluctance and delay and at this time we still do not know whether the
problems are related to the quality of workmanship or are due to some
unidentified design flaw. BNL created a dedicated task force charged
with identifying root causes of the failures with the report date in
December. At the same time, the BNL engineers are completing
specifications for an engineering study of a back-up solution. The
discussions with Wiener has been initiated and the contract for such
study and a prototype is expected to be placed in November/December.

The progress on the commissioning of the cryostat, Level1 receiver and
of the Forward Calorimeter is described in the individual contributions
below.

For the last few reporting periods we have been looking into why the
Quality Meters of the Barrel Cryostat appear to have a zero shift of
some 100 pico farads. All of the meters worked well in bldg. 180 but
upon cooling the cryostat down and filling with LAr, all of the six read
with the zero offset. Cables and calibrations were checked and rechecked
but everything was in working order. After some telephone discussions
the problem was diagnosed to absorbed moisture in the G-10 spacers of
the meters capacitor plates. A spare Quality meter at CERN was measured
and read over 200 pf in the shipping box but when dry and calibrated
read 120pf. Spare meters, resident at BNL, read 160pf in an air
conditioned environment. Unfortunately, there are no plans to warm up
the Barrel Cryostat at any time in the future so the offset problem will
remain. Shifting the zero offset was tried but the circuitry does not
have enough range to adjust out the error.

The four End Cap Cryostat Quality Meters are in the process of being
welded into the system. Time will be allocated for drying the G-10
spacers, as determined by its room temperature calibrated tare value.

During the third quarter of 2006, the Pittsburgh group has begun the
manufacture of two new types of LSBs, designed to compensate for wiring
errors in the endcap calorimeter (discussed in the previous quarterly
report). The new boards have been produced, and the wiring of one type
(R1x16L) is complete, and the wiring of the other (R1x8H) is under way.
Tests of production prototypes of each have been made, and the mapping
has been verified to be correct. Steps remaining are the burn-in and
testing for both types of boards, which will be carried out in
October-November. The set of patch cards (boards mounted below the
baseplane which reroute 8 of the signals in two FEBs, also needed to
solve the wiring problems) have been built and tested at BNL and were
installed in the pedestals in September.

In the commissioning of the barrel system, we continue to work on the
timing measurements of the L1 signals, where we compare the time
measured in the L1 and main readout with that calculated taking into
account all of the known cable lengths and PCB delays. This comparison
is necessary to permit the setting of the delays in the TBB, which can
only be done if the relative cable and PCB propagation delays for each
depth layer are known.

Commissioning of the endcap A is also under way. The first step is to
carry out connectivity tests, where we establish that the signals are
seen in the expected channels when a given calibration channel is
pulsed. We have looked at all baseplanes, and the only problems seen in
the EMEC are those associated with the miswiring of the calorimeter
mentioned above. For the HEC, some problems were seen, but these were
traced to errors in the data base. For the FCAL, no problems have been
seen, except for one bad channel, a known problem.

At Pittsburgh, we have been testing the small TOF system we have built
to be used for establishing the timing between the two halves of TT15,
which is split between the barrel and endcap. This measurement will
provide the required length of the set of eight cables need to be made
to perform the analog sums in the endcap receivers. The system is
functional and its timing resolution is extremely good. It will be
implemented at CERN after the endcap calorimeters are operational.

**John Rutherfoord (University of Arizona)**

During July and August, commissioning calibration data was taken on
FCalA. Several anomalies showed up. Most could be explained, a few will
require further investigation, and one pointed to a new problem. Already
in the TDR tests we had seen on a few channels which appeared to have a
slightly higher Ohmic resistance at the signal feedthrough. The recent
commissioning data showed no calibration pulse (other than a small
crosstalk from adjacent channels) on five of the six such channels in
FCalA. We realized that there must be a disconnect between the
calibration line and the signal line. For good channels the TDR sees at
the baseplane the pigtail and the calibration injection resistor in
parallel. For channels with disconnected calibration line the TDR sees
only the pigtail. This small difference in impedance is what we
misinterpreted as a higher Ohmic resistance on the feedthrough.

The most likely cause of this disconnection is a poorly soldered
calibration injection resistor on the baseplane right next to the
baseplane connector to the FEB. We have looked at a spare FCal baseplane
with an Ohm Meter and found that all 1,792 calibration injection
resistors are connected. So it is a puzzle why five such channels show
up on the FCalA baseplane. From TDR tests on FCalC we see no such cases
of this anomaly so, when commissioning calibration data is taken on the
C-end, we expect to find no disconnected calibration injection
resistors.

Luckily the underside of the baseplane is not completely inaccessible
although it is a major effort to remove all the boards in the Front End
Crate, remove the crate, and then dismount the baseplane with all the
warm (pedestal) cables. A campaign to make repairs is being planned.

We have been bombarded with a large number of "emergency" requests and
have reacted promptly. For instance, Athena-based Monte Carlo studies of
single particles directed into the FCal showed an alarming energy loss
upstream of the FCal. This was traced to the Boron-doped polyethylene
shielding in the "alcove" just upstream of the FCal. We were able to
finger the problem as an incorrect (anomalously large) density entered
into the Monte Carlo. We now have a piece of that boron-doped
polyethylene and will make an accurate measurement of its density.

In the process of uncovering the problem with the Monte Carlo we learned
that the pixels apparently contribute quite a bit of material, in their
services, upstream of the FCal. This is puzzling since the pixels
themselves cover only up to about η = 2.5 and particles from the IP
aimed in the direction of the FCal don't even exit the beampipe until
well downstream of the interaction region. We are curious to find out
what pixel services are so close to the beampipe so far downstream of
the interaction point. We suspect another mistake somewhere in the
simulations. But it has been hard to get information from the pixel
group.

Sasha Savin has created an interactive (root-based) display program
which allows the user to interrogate any channel in the FCals. The
display shows either the C-end, the A-end, or the calibration test beam
configuration. As an option one can superimpose a color-coded shading of
channels to indicate the few dead channels and those channels requiring
special attention in the analysis. Recently he added the capability to
display the TDR data for the selected channel from his huge data base.
He also displays the envelopes for normal channels so the novice can
look for anomalous behavior.

Questions about the signal mapping keep coming up, mostly from the
offline software groups. Often their questions are a bit orthogonal to
the way we organized our mapping files so we have to work through the
files in a new way. Because the mapping of the FCal is not
straightforward, such requests can take quite a bit of work.

Rutherfoord spent the month of July at CERN working on setting up for
our test beam run at Protvino. The EMEC, HEC, and FCal groups have each
made very small pieces of their calorimeters. The FCal piece, dubbed the
FCalchik, is 50 mm deep, 60 mm high, and 90 mm across. It has 16 tube
electrodes with the normal liquid argon gap of 250 microns and 16 tube
electrodes with smaller 100 micron gaps. The FCalchik also has a liquid
nitrogen cooling loop near the periphery. ("chik" is a Russian
diminutive suffix.) Each calorimeter piece will be housed in its own
small liquid argon cryostat in order to isolate contaminants, should
evidence for any show up. Each cryostat will have a standard ATLAS
purity monitor, thanks to Christian Zeitnitz, formerly at Mainz, now at
Wuppertal. Arizona is responsible for the FCalchik module, the argon
purifying system for all three cryostats, and the beam trigger.
Rutherfoord has also written the unpacking algorithms for the offline.
The three cryostats will be placed in an extracted 60 GeV proton beam
provided by the Protvino (formerly Serpukov) accelerator at IHEP. The
FCal cryostat will come first. Then after some absorber will come the
EMEC cryostat. After some spacing the HEC cryostat will come last. The
positions are such that the ratio of the rates of energy density
deposited in each module are close to those expected in ATLAS.
Rutherfoord worked out all these rates and ratios. We will start with a
few protons per rf bucket (1.0 microsec between buckets) and ramp up the
intensity as far as possible, hopefully well above the design at the
upgraded LHC. We plan an integrated exposure approaching a run year. One
goal is to test Rutherfoord's predictions for the critical ionization
rate and the pulse shape changes which occur above that threshold. Setup
at Protvino is scheduled for mid November and the first run is presently
scheduled for sometime in December.

While at CERN in July Rutherfoord spent a few days at Orsay measuring
the shape of the calibration pulse on the FCal baseplane, something our
Orsay colleagues were eager to do but needed a little help. With Laurent
Serin we measured this pulse shape on a spare FCal baseplane (now at
Arizona). It was found that the calibration pulse shape varies slightly
with baseplane slot number. That is, the distance the Front End Board is
from the pulser board affects the pulse shape as injected into the
preamp due to reflections on the traces on the baseplane. We are now
analyzing this data and we find that once these pulses come out of the
shaper, any differences are greatly reduced, as expected. While we will
generate a correction due to these effects on the baseplane, this
correction will be very small.

Also while Rutherfoord was there, he asked de La Taille to measure the
transfer function of the preamp. Christophe did this and Rutherfoord is
analyzing this data. Rutherfoord also learned that Fournier, with a
graduate student, has measured the input impedance as a function of
frequency for a number of preamps. The data goes up to about 100 MHz. We
now have that data too and are trying to understand our own measurements
of the preamp input impedance taken in the EMF in summer 2005 in terms
of these new measurements. (Incidentally, Lanni has preamp input
impedance measurements which are at odds with Fournier's. We will try to
sort this out.

**3.4 Subsystem Manager\'s Summary** **Larry Price (ANL)**

Extensive work was done on achieving a fundamental understanding of the
problems with the low voltage power supplies (LVPS). Progress during
this reporting period set the stage for an engineering "Experts Week" at
the beginning of October and crystallizing plans for modifications made
by the end of October. Meanwhile, roughly half of the Barrel Calorimeter
was instrumented with LVPS with temporary overvoltage protection (OVP)
so that other aspects of commissioning could proceed. In cooperation
with ATLAS Technical Coordination, most of the Barrel was provided with
cables and services and the cables tested and validated by the end of
this period. Gap and MBTS scintillators were tested (to the extent
possible with restrictions on the use of radioactive sources) and light
sealed. Barrel modules with LVPS were extensively tested and read out
with the TDAQ system. Joint cosmic ray runs were taken with the LAr and
(at least once) the muon system. The cosmic ray data taking increasingly
became part of an ATLAS-wide effort of Phase 2 commissioning, aimed at
advancing smoothly to a state where the whole detector can be read out
together in preparation for LHC collisions.

*(a) Repair and Maintenance of FE Electronics*

During this period no PCB repair work was needed since no faulty cards
were returned. Substantial repair will be reported in the next period.

*(b) Commissioning and Integration work*

During this period Chicago maintained a team of 8 people resident full
time at CERN to contribute to commissioning and integration work. Six
were supported by Research Program M&O funding.

By the end of this period all services were connected to the 128 barrel
drawers of the barrel calorimeter. This includes the following
connections: trigger, HV, laser, LV 200V local, LV 200V from USA15, LV
Aux cables local, LV Aux cables from USA15, TTC fibers, CANbus cables
for Integ/HV, CANbus cables for LV, smoke sniffer tubes, cooling tubes,
cesium tubes. In addition, 68 LV supplies were installed in the
calorimeter fingers.

On the extended barrel, A side, CANbus daisy chains and ferrites were
installed in all fingers. Local AUX and 200V cables were installed and
certified. Trigger cables were installed and certified. All other cables
except HV were made ready for installation. About 90% of the cesium
cabling and piping was completed.

On the extended barrel, C side, CANbus daisy chains and ferrites were
installed in all fingers. Local AUX and 200V cables were \~70% installed
but connections and QC were not completed. Installation of cable trays
prevented work in Sectors 11,13 and 15. About 75% of the cesium cabling
and piping was completed.

Chicago personnel played an extensive role in the services installation
and testing.

An extensive effort is underway to provide, test and install a temporary
version of the LVPS system for each electronics drawer. By the end of
this period about 68 of the 128 supplies had been installed for the
calorimeter barrel but it is understood that their operation is
unreliable and that they will have to be removed once a more robust
version of the supply is available. It is useful to have them installed
to study other aspects of the calorimeter system.

Two members of the Chicago team have been helping with the QC of the
completed LVPS assemblies.

**Kaushik De (University of Texas at Arlington)**

Two students from UTA are stationed at CERN full time to work on
TileCal - Hyeonjin Kim and Rishiraj Pravahan. In addition, Carlos Medina
spent the summer at CERN. Kaushik De spent a substantial fraction of
time also at CERN.

Rishi and Heonjin took TileCal shifts and participated in various EB and
ITC related pre-operations work. Special shifts were also set up every
evening to calibrate the ITC scintillators with SR-90 radioactive
source. The shifts also tested all EB channels (within a drawer) using
MobiDick for light leaks or electronic problems. On average, one drawer
was tested every evening. Results were fed back to the CF electronics
group and reported in weekly Commissioning meetings.

We discovered a problem with the fiber sleeves just before closing the
EB\'s for the magnet tests. There was significant risk of crushing
fibers in some regions. UTA and MSU team members worked in emergency
teams to fix these problems for a week, by cutting the sleeves. For the
final two days, access was only possible from a basket lowered with a
crane. The operations were successful in safely closing the EB\'s on
schedule.

The process of cutting the sleeves created light leaks. The MSU team
came back in September and put additional light protection sheets on the
ITC scintillator region.

**Joey Huston (Michigan State University)**

During July-Sept 2006, the Minimum Bias Trigger Scintillators plus
covers were installed on both the A and C sides. At the same time, the
forward moderator sections were also installed. It was noticed that
there was a conflict between the optical cables reading out the MBTS,
cryostat and gap scintillators and the inner detector. To avoid any
damage to the cables, the light sheath covering the clear fibers in the
readout cables were cut. This necessitated a major modification of the
light-tightening of the forward scintillators which was carried out in
this time frame.

MSU technical personnel also assisted in the fabrication and
installation of cables for the Tilecal system. They also modified the
design and installed a magnetic shield for one of the finger power
supplies on the C side.

Graduate student Brian Martin assisted in the above work and in addition
worked on the diagnostic testing of the Tilecal readout.

**James Grudzinski (ANL)**

With regard to the ATLAS detector movement system, the system was used
for several movements of both the A- and C-side End Cap Calorimeters
including the first movements of the A-side as well as the first closing
sequence for each side. The automatic leveling system was tuned and
tested successfully during actual movements on the air pads. Progress
was made in the final documentation of the system and the knowledge
transfer in such a way that the movements at the end of this period were
now being carried out solely by the CERN staff. System interfaces to the
Metreel service cable carriers and the liquid argon safety line were
implemented and tested. A new position sensor was incorporated.
Discussions were continued with the team making the big wheel movement
system in regard to the eventual integration with the detector movement
system.

**Robert Stanek (ANL)**

After a large number of modified LV supplies were constructed, ANL and
MSU personnel spent time getting these things installed and operational.
Larry Price headed up the LV project at the organizational level. At the
end of this period we had installed about 60 power supplies, and had
learned how to live with them.

In addition to getting the barrel components operational, a large
fraction of effort was spent on developing and understanding the
results. The sheer volume of information is a problem we struggled to
deal with and have developed many tools for the future for databases and
analyses. Larry Nodulman, Rik Yoshida, Sergei Baranov and Dave Underwood
have contributed valuable experience to guide this effort, and this has
been key in keeping us on track.

Dave, in addition, had designed, constructed and installed a set of
pulsed LEDs to commission and understand the optical system of the
barrel. This has proved very important in monitoring the effects of the
toroid field as well as knowing the timing across the detector.

**Steve Errede (University of Illinois, Urbana-Champaign)**

During the July-Sept 2006 period two members of UIUC, David Forshier and
Irene Vichou continued to contribute to the commissioning of the TileCal
detector, now fully assembled in the underground cavern UX15.

David Forshier, a technician, worked in the provisioning and QA of
trigger cables for the two Extended Barrels. David helped in other
services activities, including the installation of daisy chain cables
around the two Extended Barrels and he showed flexibility in moving from
one task to another.

Irene Vichou has continued to work on the commissioning of the TileCal
detector, being the run coordinator for the phase I operations and the
phase II coordinator (together with Christophe Clement). In both cases
her role is to evaluate the priorities and feasibility of several
subtasks and to plan in such a way that there are no conflicts and
intermediate milestones are fulfilled in order to reach the full
operation with the expected performance.

Concerning phase I (detector standalone operation) the following
achievements have been made:

\- Fulfillment of the connection of the Barrel part to the services
provided by the Technical Coordination.

\- Final certification of the FE electronics of the full barrel.

\- Equipment of 1/2 of the Barrel with LVPS which have to be studied
systematically for robustness and stability of operation.

\- Extended checks of the FE electronics operation using the final RODs
for readout and commissioning exercises.

\- Very well elaborated procedures to evaluate with data the operation
of the hardware in a very user friendly manner. This will facilitate the
detection of problems or the decision making for an element to be
certified.

Concerning phase II (integration with systems as Trigger, DAQ, DVS,
other calorimeters):

\- We have defined real milestones for the intermediate steps till
October for the integration with the above systems.

\- Integration with the ROSs in the DAQ part is in good progress,
TileCal signals were given to the LVL1 calorimeter group for testing.

\- Using a local back-to-back tower TileCal trigger, we have defined a
combined run with the LAr EM calorimeter for mid-July for purposing of
matching events together to common runs with cosmic muons.

Irene, as the person responsible for the definition of the EM scale of
TileCal for data-taking (starting point for calibration) gave a summary
talk on this subject at the ATLAS Hadronic Calorimeter Calibration
Workshop held in MPI, Munich between 3 and 5 of May.

**3.4.2 Calibration & Monitoring**

**3.4.2.1 Pre-Operations** **James Pilcher (University of Chicago)**

During much of this period Chicago graduate student Martina Hurwitz was
the co-leader of Team 5, responsible for monitoring the test and
calibration data collected with the operational calorimeter modules. She
has been working with Chicago students Imai Jen-La Plante and Eric Feng
to streamline the process of extracting calibration constants using the
charge injection system. In particular, a number of modifications and
improvements are being made to Athena to facilitate the process.

**Kaushik De (University of Texas at Arlington)**

During the summer, after a long wait, we received permission to use a
SR-90 radioactive source to test and calibrate the ITC scintillators. We
were only allowed to use the source during the evening. Shifts were set
up among UTA people for this purpose.

Each day, the CF team hooked up a MobiDick to one drawer on the EB. For
the last few days, we had access to both MobiDick\'s. During the
evening, a team of three people from UTA took data with the MobiDick
using the source. Integrator data was taken with HV ON and OFF for all
channels. The source was moved to expose all the scintillators serviced
by the drawer. All data were recorded (and saved electronically).

These calibration runs showed that all channels that we were able to
test had sufficient light. Some light leaks were discovered and fixed.
Some channels had lower light than expected - though still above
threshold. We expect these were caused by damaged/broken fibers.
Overall, these runs were extremely useful in testing and calibrating the
scintillators in place for the first time.

**3.5 Subsystem Manager\'s Summary**

**Frank Taylor (MIT)**

At the end of September-06 some 28 BW sectors - all 16 of BW-C and 12
out of 16 of BW-A were assembled, tested and stored. In addition, 11
EIL4 stations were integrated with their corresponding TGCs and
alignment bars and tested. The total number of EIL4 stations installed
in UX15 is five.

Planning studies were undertaken on the SW assembly task to be conducted
in B191. A service installation workshop for both the BWs and the SWs
was scheduled for 12-13-Oct-06 at CERN.

The assembly of BW sectors in B180 proceeded well but the schedule
continued to be threatened by rework necessary on the so-called H-beams
(outermost beams of the sector) and the fabrication of needed storage
tooling.

The delivery of alignment parts remained ahead of the critical path
(defined by the mechanical assembly of BW sectors and EIL4 frames) and
at the end of September all the BW alignment bars were delivered to
CERN. In addition, all the alignment bars for the Small Wheel A were
delivered to CERN. The alignment bars for SW C have been constructed at
Freiburg and, after calibration, will be shipped to CERN in mid
December.

A program was carried out to replace all CSMs used in the MDT EC system
with upgraded ones that have less jitter by means of mounting a true 50
MHz clock. A clever hardware implementation was developed by the
Michigan electronics team that used pre-existing connection points on
the CSM board as solder points for the crystal clock mounted on a small
mezzanine board. This upgrade program was successfully carried out and
by the end of summer all CSMs were fixed and all BW and EIL4 stations
were outfitted with the improved version.

The integration and testing of CSC proceeded in B184 with BNL,
University of Arizona, University of California -- Irvine and Stony
Brook personnel. All CSCs were outfitted with final electronics and were
mounted on their respective support frames. A trial installation and
commissioning of the alignment fixtures were done using the CERN CMM.
Cosmic tests were made.

  -------------------------- -------------- ---------------- -------------- ----------------

**Note #1**  This project has been ahead of the UX15 critical path but
was delayed due to CERN technical resources and various reworks
necessary to make the Al frames (made in Russia) fit. At the end of
Sep-06 11/16 stations were integrated and 5/16 installed in UX15. The
integration of the EIL4 stations with support frames and TGCs was
completed 29-Oct-06. As of 23-Nov-06 there were 11/16 EIL4 stations
installed in UX15.

**Note #2**  The SW is significantly delayed - primarily due to the
delays in gaining working space in B191 where the wheels will be
assembled. A work-around plan was developed where the SW tooling will be
located on the mezzanine, while the ECT and JD disks are occupying the
floor. The steel work of the tilt table has proceeded slowly due to
lower priority assigned to it by the CERN team (BWs - TGC & MDT before
SWs). As of 23-Nov-06, the mezzanine was cleared ready to receive the
tilt table and the table is ready to move into B191.

**Note #3**  The critical path for the MDT installation and
commissioning is set by the installation and commissioning of TGC1 that
has to go in first. The installation of TGC1 commenced on 05-Jul-06 but
was not finished until 20-Nov-06.

**Note #4**  Delayed - the TGC1 wheel installation on the HO steel
structure was completed on 15-Sep-06 but the installation and
commissioning of the TGC1 chamber services is taking longer than
expected. Some structural reinforcements had to be made to the TGC1
wheel as well. The load was transferred on 20-Nov-06.

Phase 3 commissioning will take place in steps - starting with
single-sector tests immediately following the installation of a sector
on the HO structure. The final Phase 3 work will be undertaken following
the full integration of the wheel with the various service platforms
attached to the hanging wheel following the load transfer.

**Note #5**  The completion of BW-A sector assembly in B180 has been
following the accelerated schedule and on 30-Oct-06 all 32 sectors of
both MDT BWs were completed in B180. The quality of the Al remains a
concern and some rework of the sector outer beams was necessary.

**Note #6**  The BU workforce was augmented in late July with the
addition of a student, a postdoc and a senior tech. Until the SW work
starts they will concentrate on the BW installation and commissioning.

**Note #7**  A senior graduate was replaced by an undergraduate in June
06. She carried the same responsibilities as Scott and worked on Phase
1.9 and 2 and gas connections.

**Note #8**  Accelerated plan put in place to finish BW-A and was
finished on 30-Oct-06.

SW in B191. See above discussion about the delays accumulated in the SW
work.

The integration of the 32 CSCs with their spacer frames and on-chamber
electronics is complete and under cosmic testing in B184. Remaining is
the integration of the alignment devices on the chambers and their
calibration using the CMM at CERN.

**3.5.3 Alignment System Pre-Operations & Maintenance**

**James Bensinger (Brandeis University)**

The complete set of Big Wheel alignment bars have been tested and
installed in the sectors for the BW. All of the EIL4 alignment bars have
been tested and either are installed in the EIL4 chamber frames or are
available to the Seattle group for installation. Some difficulties have
been encountered installing the EIL4 bars because of problems due the
fact that these chambers are installed under difficult conditions with
many other chambers in place. All of the bars for the Small Wheel side A
are complete and the side C bars are complete and are being measured at
Freiburg, expected completion by mid-December. All of the EO components
are complete and have been shipped to CERN. The CSC components are still
being developed and we anticipate delivery by the end of January.

**3.5.3.3 Alignment System Maintenance (Beam Off)**

**James Bensinger (Brandeis University)**

A temporary readout for the alignment system will be attached to the BW
sectors as they are installed in the ATLAS pit. It will be made
operational sector by sector as the sectors are installed. This will
system will be used to determine of the installation of sectors are in
their proper place.

**Andrew Lankford (University of California, Irvine)**

Pre-operations activities included hardware commissioning and
maintenance, software commissioning, and support of TDAQ and detector
commissioning. RoIB commissioning, rack commissioning, and network
commissioning continued. The hardware and software of the Pre-series
system was maintained. Considerable effort was invested in software
commissioning, including functionality, performance, and scaling tests.
Tests of the full HLT/DAQ chain using pre-loaded simulation data on the
Pre-series system were set up. A series of 24-hour technical runs on the
Pre-series system was continued in order to test system robustness and
operability. Commissioning of detector systems was supported,
particularly through commissioning detector systems with the Readout
Subsystem (ROS) and in developing software tools for monitoring and
calibration. Commissioning and debugging of TDAQ systems was also
supported, including a test of a full HLT/DAQ calorimeter slice on the
Wisconsin testbed and tests of a full HLT/DAQ electron/gamma slice on
the Pre-series system.

**3.6.1.1 Supervisor RoI Builder**

**Robert Blair (ANL)**

Jinlong has been in contact with Bruce Barnett and the expectation is
that in October fibers will be pulled to allow for testing the LVL1 Calo
system with the RoIB.

In July Jim tested the interface between the CTP and the RoIB.

**Bernard Pope (Michigan State University)**

The ROIB Input card was equipped with the HOLA LDC in the 3rd SLINK slot
and is ready to take data from CTP. The remaining FILAR cards were
received.

A meeting between the LVL1 and the ROIB teams took place to discuss the
test plans for August.

The remaining HOLA cards for the ROIB setups were received. The
LVL1-ROIB test was postponed in August, as the Level-1 team was busy
with design reviews. However, in September, preparation of the test
setup for a PC based RoI builder has started in the building 32 test
bed. Three PCs have been equipped with the FILAR cards.

Ermoline made an oral presentation of the \"ATLAS TDAQ RoI Builder and
the Level 2 Supervisor system\" during 12th Workshop on Electronics for
LHC and future Experiments in Valencia.

The rack DCS work continues. The TDAQ DCS PCs are ready for
installation.

DIN rails for ELMB and terminal blocks were installed in the first rack.
Sensor cables were made and installed. The layout of the racks in the
SDX1 counting room was re-entered in the Rack Wizard and all components
were updated according to the latest definitions. The DCS PC was
installed in USA15 (power, registration, networking, OS). PVSS and
Framework were also installed and a development project started. A first
meeting with the central ATLAS DCS team took place in order to discuss
the integration of the TDAQ rack DCS into the overall ATLAS DCS. By the
end of September, the CANbus PSU and one power module have been
installed in the USA15 DCS rack. Therefore a complete DCS chain (DCS PC,
PSU, ELMB, sensors) is available. Two prototypes of the operational rack
panel (one with trending plots) have been developed. Ermoline reported
on the status of the rack DCS work at the UC London TDAQ workshop.

**3.6.1.2 Communications and Travel**

**Robert Blair (ANL)**

Jinlong Zhang joined the ATLAS group in Sept. He will be resident at
CERN. He spent two weeks at ANL learning about RoIB software and
hardware. He then traveled to CERN to provide RoIB support, participate
in test runs and to set up the support lab for the RoIB.

Hardware Commissioning:

Unel assisted in the commissioning of the final Readout Subsystem (ROS)
nodes. Ciobataru and Stancu monitored the TDAQ network at Point 1. Some
oscillations in data rates remain to be understood.

Hardware Maintenance:

Ciobataru and Stancu updated documentation and databases describing
network equipment, connectivity, and configuration. Ciobataru continued
development of a tool for monitoring network performance mpNetPerf,
including uncovering the fact that the Linux kernel can drop UDP packets
without notification under certain circumstances. This tool can now be
used to determine the effective buffering capacity of any network
configuration, which is a critical parameter for determining the setting
of parameters in the Event Builder (SFI) software. Stancu provided
graphical output and other tools for network database queries. Ciobataru
participated in testing of a network emulator used for network switch
testing and maintenance.

Software Commissioning:

Wheeler investigated the feasibility of using the Manchester University
GRID cluster for running large and medium scale tests of the TDAQ
software. Stancu supported these studies.

Wheeler worked on preloading of simulated event data into ROS's for
system testing and studied memory utilization. Subsequent system
performance tests performed by Unel, Wheeler, and others focused on
testing High Level Trigger (HLT) algorithms within the HLT/DAQ system. A
system with multiple real ROS's feeding data to LVL2 and EF systems was
operated with simulated events. The system was successfully run
overnight. It was triggered with the RoI Builder. Additional tests were
also performed with the new TDAQ release (1.6).

Unel performed measurements of system performance of the most recent
TDAQ release (1.6.0) in the absence of HLT algorithms. Unel organized a
series of 24-hour runs of the TDAQ system to test robustness and
operability. Wheeler participated in debugging the problems observed in
these test runs, and she tested some prototype cluster monitoring tools.
Kolos also participated. The September run used TDAQ release 01-06-00.

Ciobataru and Stancu assisted with the use of a network emulator to test
the fault tolerance of TDAQ software applications under controlled
conditions of network degradation.

Detector Support:

Bold added functionality to HLT services to ease detector commissioning.
Kolos participated in debugging the latest TDAQ software release at
Point 1, where some problems were observed by some detectors that were
using it for commissioning. All issues were resolved.

TDAQ Support:

Stancu helped troubleshoot a standalone ROS setup for release 01-06-01.
Unel assisted in converting the Liquid Argon Calorimeter ROS's to the
new TDAQ release. He also participated in standalone ROS testing
performed at NIKHEF. In support of commissioning other TDAQ subsystems,
Unel, Wheeler, Kolos, and Stancu participated in 24-hour technical runs
on the TDAQ Preseries system at Point 1.

**Robert Blair (ANL)**

Jim Schlereth has put together code to allow for a run controlled PC
equipped with QUEST cards to act as a LVL1 source. This will allow for
large scale tests without the need for LVL1 components, The system from
the LVL1 fibers through the EF can be tested this way with MC generated
data.

Changes in the framework require some migration of the L2SV code to
adapt to new streaming/routing requirements. Both the RoIB code and the
L2SV code is being modified to use the new ERS.

Code to monitor differences that occur between the RoIB data and data
recorded by the ROS has been included in the TDAQ release.

**Bernard Pope (Michigan State University)**

Alessandro DiMattia continued the work initiated in June, putting the
online integration at low priority. On this item the work is presently
stopped: He has not investigated the multithread problem, but has had no
complaints from the people working on Testbeds concerning the
functionality of muFast while operated in a single thread together with
other LVL2 slices. Hence he concludes that everything is working well in
this area.

Details of other items follows:-

1\. DiMattia's work for the HLT review has been terminated with the
1-day workshop held on the 21 of July. His presentation focused on items
still opened on muFast. The slides can be found in the usual place

https://twiki.cern.ch/twiki/bin/view/Atlas/MuonHLTReviewLVL2muFast

2\. Concerning the muFast extension, preliminary results are not
encouraging: it is quite hard to reach performance on muon momentum
measurement, using LUT methods, close to those obtained in the barrel.
The reason of this it is probably the inhomogeneity of the magnetic
field along the muon trajectory, which makes the description of the
trajectory more complicated with respect to a naive model that assumes a
constant curvature (like the one employed for the barrel). Di Mattia is
investigating other possible sources of the bad performance (for example
bugs in the analysis). This work is ongoing and, while the Israeli
colleagues are more concentrated on the TGC data processing, he is
focused on the pattern recognition in MDTs + some analysis for
understanding if other variables can be exploited in order to make a
more accurate description of the muon trajectory.

3\. The muComb algorithm has been finalized and put into the CVS
repository. Its performances, in the barrel region, appears to be very
good, but they are not yet in a shape to be presented. In fact, during
the work for implementing the Z-match between the reconstructed tracks
it was realized that the single muon production has a bias: the muons
have been generated with no vertex spread. This invalidates the results
obtained in the z-match.

Di Mattia's work in August was mainly focused on the extension of the
Level-2 standalone muon reconstruction in the endcap. He also worked on
the Level-2 muon combined algorithm. In more detail:

Endcap extension: in August some bugs in the reconstruction of the TGC
data at level-2. Once fixed, the full production of the events (4\*106)
has been re-done. After looking at the new data produced, things appear
to be less confusing than before. However there remain some problems for
the momentum reconstruction, but the analysis for the pattern
recognition seems to behave as expected. A big step forward has been
achieved in September, by implementing a procedure that provides a \"non
optimized\" estimation of the muon pT in the full endcap. This allows us
to operate the muFast algorithm in the full spectrometer, even if the
pattern recognition is not fully working yet. This latter is going to be
implemented soon, because the procedure to be used has finally been
identified. Preliminary results show that it can be used on the full
endcap, even in those regions where the magnetic field is inhomogeneous,
and that the corresponding efficiency is quite high. The details have
been presented in the TDAQ workshop in London:

http://indico.cern.ch/conferenceDisplay.py?confId=a061351

The next step is the implementation of the data extraction for the
calibration of the Spectrometer, and the finalization of the pattern
recognition. The former is expected to be completed in early October.

muComb: results from the new production are fine and quite promising.
They have been presented at the TDAQ workshop of London. The next step
is to compute the trigger efficiency curve for the single muons.

The sharing/cross mounting of disk space between machines has been
implemented on the MSU cluster. On each machine a /scratch/work
directory was created and auto mounted through the autos to: /work/local
and /work/\<machinename\> on the local machine and /work/\<machinename\>
on all other machines

Di Mattia has started to use the MSUcluster for doing the massive
productions needed for the trigger studies. As of now \~ 6\*10^6^ single
muon events have been transferred and processed on the cluster. Di
Mattia finds the cluster very efficient for the trigger processing,
apart from the network speed which is very slow (10 Mbit/s). This
produces a bottleneck while events are transferred from castor. However,
an upgrade of the network speed could increase the sensitivity to the
init time of the job, when it accesses the oracle database for
configuring the geometry. Since the events are divided into files having
1000 muons, the init time cannot be neglected with respect to the
overall execution time needed to process a file.

A meeting concerning the MSU cluster upgrade and video-conferencing
organization took place in August between Schwienhorst, Ryan and
Ermoline. It was decided to acquire four more dual CPU machines for the
cluster and convert the single CPU machine (PCMSU001) to a video
conferencing base station. By the end of the quarter, these additional
machines have been received and they are being integrated into the
existing cluster. At the TDAQ meeting in London, Pope, Schwienhorst, Di
Mattia and Ryan planned work on the integration of different triggers in
the Level 2 trigger as a whole. We also plan to work on triggers
specific to Top Physics, most importantly those triggers needed for data
coming from early runs. We are involved in analysis and documentation
for CSC Technical Note 8.

Abolins also attended the London conference and participated in the
inaugural meeting of the \"Trigger Configuration Review Panel\" chaired
by Mike Medinnis. In addition, Abolins worked on issues facing the TDAQ
Speakers\' Committee in the coming year (with Hans Peter Beck and Haimo
Zobernig)

**Werner Wiedenmann (University of Wisconsin, Madison)**

Pre-Ops Software Commissioning:

When running tests on distributed dataflow systems dos Anjos identified
and fixed the following problems:

\- A problem in the L2PU data collector. When requesting N ROB fragments
only N-1 were returned. The problem was originally identified as
discrepancy of reconstructed calorimeter energies when running online
and offline.

\- A problem in the ROS emulator (ROSE) when working with large
preloaded datasets. The ROSE kept in memory all the ROB fragments which
were found on the input files and not only the ones which were assigned
to it. Fixes were provided for TDAQ 1.4.1, TDAQ 1.6.0 and the head
version of the CVS repository.

\- When cycling states problems in the ROSE (memory leak) and the L2
Supervisor were identified when working with preloaded data. For both
problems patches were provided.

\- An unpatched problem in the DFM application was identified which
caused the back-pressure mechanism not working as expected. An overflow
of events in the Event Building phase was observed. The problem was
reported back to the main developers of the package.

Together with developers from the SLAC group Wiedenmann was running
tests with HLT algorithms in athenaMT using the newly developed database
proxy application \"dbproxy\". Several issues with badly formed SQL
requests were identified and reported back to the developers.

TDAQ Support:

Complete selection slice for LAr:

A dataflow system was put together on the Wisconsin test bed running the
e/gamma-, jet- and tau-selection code in Level-2 and Event Filter. In
total 11 processors were used. The setup included

\- 1 L2SV, 1 L2PU for Level2

\- 8 ROS emulators for the ReadOut System

\- 1 DFM, 1 SFI for the Event Builder

\- 3 x ( 1 EFD, 2 EFPTs ) for the Event Filter

\- 1 SFO running in dummy mode (no event output)

\- the entire TDAQ online software infrastructure

The software was used from the releases TDAQ-01-04-01 for online, Athena
11.0.6 for offline and HLT-03-00-04 for the HLT infrastructure. A total
of \~3500 fully simulated events (dijet and single electrons) were
preloaded into the ROSEs and the L2SV. These events were preselected
high-PT events and thus most of them actually triggered both Level-2 and
Event Filter (EF), exercising all parts of the system. The whole system
was controlled from the TDAQ panel and ran at about 10 Hz. The rate was
limited by the processors used for the Event Filter applications.
Progress was observed by looking at the various counters and histograms
available in the TDAQ panel for the online applications. Further the HLT
algorithms in L2 and the EF filled histograms which were regularly
updated and could be inspected with the online histogram display
(oh_display). The setup was shown to members of DOE and was also
presented in the PESA meeting to the developers. In a second iteration
the setup was upgraded to the latest bug fix releases of offline, TDAQ
and HLT. Further the histogram \"gatherer\" application was integrated
in the system. With this summary histograms of all Event Filter
applications could be displayed in the online histogram display.

The setup was also used to perform stability test with several different
input datasets. This included also a 25 h stability test on the
Wisconsin testbed. In this test a total of 1.2 million events were
processed in L2 and about 1 million in the EF with an overall average
rate of 8-12 Hz. Memory leaks were identified in L2 of about 300
bytes/event and in EF of about 12 kbytes/event.

The integrated setup builds the basis for further testing with more
applications on the preseries system.

Testing with release 11.0.5 at Point 1:

Tests were run with HLT algorithms for e/gamma selection from offline
release 11.0.5 in Point 1. Problems occurred due to recycling of events:
the same L1 identifier could appear multiple times in the dataflow
system. To avoid this the system was artificially slowed down with a
time delay in the L2 Supervisor. The investigation and possible solution
of the problem is ongoing. It was also tried to use the real ROS for
preloading the simulated data.

Testing with offline release 11.0.6 and HLT release HLT-03-00-05:

After the build of HLT release HLT-03-00-05 and HLT image version 0.6.2
Wiedenmann ran acceptance tests on the Wisconsin test bed before
installation in Point 1. This included complete dataflow systems with
Level-2 and Event Filter. Several issues were identified and patched for
the final release. After installation in Point 1 partitions with the
following configuration

\- 1 L2PU + 8 ROS + 8 EF/PT

\- 12 L2PU + 8 ROS + 16 EF/PT + 2 SFI

\- 2 L2PU on one machine + 1 ROSE

\- 12 L2PU (2 L2PU on one machine) + 1 ROSE

were used for further tests of the installation. During the tests it was
observed when 2 L2PUs are run on the same machine the system slows down
after about 3 minutes by about 10% in rate. Further it was observed that
Event Filter Processing tasks don\'t use all of the available CPU
resources. Both problems are presently not yet understood and under
further investigation. Tests on the Wisconsin test bed have been
therefore setup to reproduce the effects.

Work for project based HLT release:

Wiedenmann ran tests with the new project based HLT release candidates.
Problems with the setup on AFS were identified. Further a problem in the
ToolSvc setup with the HLT framework was identified and fixed. This was
necessary for the monitoring setup for LAr commissioning.

**3.6.2 Operations**

**Andrew Lankford (University of California, Irvine)**

Operations activities included maintaining the Region-of-Interest
Builder (RoIB) hardware and software, software maintenance, and
operations. Considerable maintenance was performed on software that is a
U.S. responsibility. Maintenance ranged from bug fixes, to accommodating
changes in other software or operating systems, to implementing new
functionality that experience has shown is needed. In the DAQ area, much
of the maintenance activity focused on RoIB and LVL2 Supervisor
software, Monitoring services, configuration database generation,
Readout Subsystem (ROS) software, and Event Format library. In the HLT
area, maintenance activity focused on HLT steering, Event Filter
infrastructure software, and muon algorithms. Development of automated
software testing continued. System administration activities are
ongoing.

Software maintenance:

Unel worked on database generation for system configuration under new
(1.6) and old (1.4) software releases. He also contributed to the
evaluation and improvement of a new configuration database creation
tool. He maintained the ROS software, adapting to the new version of
scientific Linux and new drivers.

Bold developed and integrated a major part of the navigation package for
the new HLT Steering. The navigation allows implementation of
topological triggers and more flexible operations on event features.
Meanwhile, he maintained the old steering code and prepared it for
12.0.x software releases. Changes were made in order to propagate the
Begin Run transition to the HLT algorithms in order to facilitate quick
changes from one run to the next.

Kolos updated the implementation of the interprocess communication (IPC)
software and of the Online Histogramming software to use the common
Error Reporting Service (ERS). He made some changes to the Online
Histogramming as a result of the 24-hr runs. He also worked with
students on some extensions to the Monitoring software.

Negri worked on Event Filter infrastructure software in preparation for
the next major TDAQ software release.

Stancu worked with a student to interface the network monitoring tools
with TDAQ Online Software.

Operations:

Unel continued to lead system administration activities. He automated
some of the configuration and shutdown procedures. He worked on
procedures for shifting critical functions from failed servers to live
servers. He improved tools used for operational monitoring. Stancu
participated in troubleshooting of network configurations and network
monitoring tools, and he assisted in more general system administration
duties during the vacation period.

**Werner Wiedenmann (University of Wisconsin, Madison)**

Software Maintenance:

dos Anjos started development of python bindings for the Event Storage
and eformat libraries. The idea is that these bindings should allow
people to rapidly develop scripts for dumping bytestream data. An
initial prototype using SWIG (www.swig.org) for generating the Python
bindings was created.

dos Anjos updated the automatic testing scripts to integrate with the
most recent version of \"PartitionMaker\" and to use the \"FarmTools\"
from the Point 1 Sysadmin group. Further the tools allow now to setup
easily partitions using either the real ROS or the ROS emulator
application. Tests were performed with the tools running Level-2 and
Event Filter together.

For the next TDAQ-common release dos Anjos provided the following
upgrades to the event format library:

\- Possibility to get/set ROB and ROD source identifiers independently.
This was a request by the ReadOut and Detector communities.

\- Possibility to construct the same event format fragment repeatedly

\- Possibility to copy the constructed event out of the scope of the
construction

\- Removal of excessive debug messages

The new code was tested on three different architectures, including a
64-bit SLC4 platform. Further the HLT interface was upgraded to comply
with the new TDAQ state machine.

Wiedenmann integrated together with J.Stelzer the new Gaudi
JobOptionsSvc with readout from the trigger database. Changes were done
for the relevant Level-2 and Event Filter packages.

dos Anjos and Wiedenmann discussed with representatives from the muon
group about the integration of the muon calibration software with
Level-2 Processing Unit. This includes essentially the communication
from the HLT framework and the muFast algorithm with the muon
calibration data collection facility.

First discussions took place how to incorporate the new data streaming
functionality in the HLT applications. dos Anjos and Wiedenmann took
part in several meetings. Wiedenmann provided a chapter for the Level-2
part in the streaming document.

Operations:

Neng Xu provided system administration services for the trigger
development cluster.

**[3.10 M&O Technical Coordination]{.underline}**

**Subsystem Manager\'s Summary David Lissauer (Brookhaven National
Laboratory)**

**Calorimeter Calibration Workshop:** A workshop to discuss the ATLAS
calorimeter calibration took place in Barcelona Spain in mid-September
2006. There were about 120 participants in the conference that covered
the full calibration chain from the online electronics calibration,
online monitoring, level I trigger calibration and off line calibration.
I was one of the six (6) people assigned to review the status of the
calibration and comment on the status and action items to be taken.
There has been quite a lot of progress since the last calibration
workshop. The Barrel Liquid Argon and Tile have seen cosmic rays in the
Experimental Hall and the procedure of the online calibration plus the
calculation of the optimal filter co-efficient has been agreed upon in
detail for the barrel EM. The rest of the calorimeters should follow the
same procedure with small changes to take in to account the differences
between the calorimeters.

There were many discussions and competing calibration schemes that would
need to be followed by the offline code. Some of the schemes are quite
similar and the efforts need to be merged. Some of the efforts are
marginal and found to be not useful and need to be halted. Thus, how to
converge on a baseline for the offline will be a major part of the
effort in the coming year.

**Barrel Calorimeter Magnetic Field Test:** The magnetic field mapping
has been successfully completed. A significant amount of data has been
taken and is now being analyzed. Preliminary results already show that
the calculations and measurements agree to the level of 20 Gauss. This
is quite positive since there are still small corrections that need to
be made on the exact location of the sensors, etc.

**Barrel Calorimeter Services & Commissioning:** The Barrel Calorimeter
has been refilled. High voltage will be applied at the end of the month
(August 2006) when the experts return from vacation. Preliminary
indications are that some of the problematic channels have improved --
but final results will be known only by mid-September.

**Barrel Calorimeter:** The HV on the Barrel Calorimeter is being turned
on. Cosmic ray data is already being taken with part of the calorimeter
that is fully instrumented. The aim is now to continue to take data with
the Barrel LAr and Tile calorimeters combined. At the same time the
signals for the Level I Trigger are already being checked.

**EC-C&A Calorimeter Placement and Assembly:** Cable schleps have
arrived and are being connected. The cryogenic lines and trigger cables
are being installed and connected. The aim is to cool down the EC-A in
October 2006 and EC-C early next year (2007).

**EC Muon Big Wheel installation:** The first wheel assembly has been
completed. The next step is to unload the wheel from the assembly frame
on to the chariots and begin work on the assembly of the second wheel.

**JD/Small Wheel Assembly:** A series of meetings took place to discuss
the assembly of the JD and Small Wheel. The second JD assembly has
started. The main problem is the delay in the EC Toroid that restricts
the space available for the assembly. (See next item.)

**Pixel Review:** The Pixel Detector had a Review in mid-July 2006 to
determine how best to organize the effort to ensure that it will be
ready for installation in time. There are a number of problems that have
developed in this complicated system. The last issue had to do with the
Barrel Al cables. The cables seem to damage easily and the manufacturing
process is suspect. A new run of cables with a slightly modified
production procedure will take place in August 2006. The Pixel is
clearly on the critical path of the experiment. The main conclusion is
that the effort needs a significant injection of experienced manpower
for the integration efforts that need to be at CERN. TC is going to try
to identify a few Sr. Physicists and Engineers to help in this effort.
Additional manpower is expected to come from some institutions that have
not been involved in the Pixel Detector to date, but can spare some
technical manpower.

**EC Toroid:** A major delay in the end cap Toroid has been found. The
design problem associated with the assembly procedure is more serious
than we thought a few weeks ago. The solution will take longer to
execute because problems were found in the final steps of the procedure
for closing the cryostat. The EC Toroid is needed for the present
installation schedule to arrive in October/November of 2006. It is now
clear that it will not be ready before April of 2-07. We have been
working on modifying the installation sequence to allow us still to
close the experiment on time on September of 2007. It is clear that at
this time some of the systems will be physically in the Hall but would
probably not be fully connected. An example of this would be the second
EC Toroid that will arrive very late. The pressure is being kept on, and
investigations continue on how one might be able to advance the
schedule.

**LHC Schedule:** There are now discussions on dropping the 450GeV run
in 2007 and start up with 14 TeV in 2008 directly. This is mainly due to
the fact that the machine does not expect to be able to be ready in
time. This is still not an official statement -- but we expect that this
will become the official policy in the spring of 2007.

**ATLAS Upgrade Project Office Meeting:** On a continuing basis, ATLAS
Project Office meetings are taking place. We heard reports from the
cooling working groups, electronics and Liquid Argon. The organization
is starting to take shape and people are working hard on defining the
problems and developing R&D plans. In some cases the R&D plans are on
going and are well advanced. It is clear that to be ready in the 2015
time scale we are already late and once the detector is installed, we
will have to increase the pace significantly.

**Operation Model:** In mid-July 2006, a task force of six (6) people
were appointed to develop a sharing of the responsibility between the
different ATLAS collaborators. With Marzio and Steinar we started to
develop a job sharing classification that will classify each of the
service jobs needed to run ATLAS to a special category. Some of these
jobs are already covered by the M&O plans within ATLAS but a large
number of jobs that traditionally are done by physicists will have to be
distributed in an equitable manner. A meeting of the full task force
took place and the needs of the Level 1 Trigger; Muon and Inner Detector
systems were presented. The numbers are VERY large and one needs to
understand better what fraction of the people are needed to be at CERN
and what fraction are needed at their home institutions. But it is clear
that a large number of full time people will be needed to start up the
experiment. These are people with both software and hardware knowledge.
The operation at the start will involve multiple control rooms with one
main control room that is mainly devoted to data acquisition and to
ensure the slow controls are working. In addition, multiple satellite
control rooms for each of the systems that will check the data quality
for the sub detector will be required.

**ATLAS Upgrade Steering Group:** The steering group met, and I reported
on the status of the Project Office and the R&D activities. Plans for
the Upgrade Workshop in October 2006 were discussed.

**Power Failure:** CERN experienced a major power failure on the last
weekend of July 2006. This is not an uncommon problem at CERN during the
summer months. The more serious effect was that the backup power that
was to be supplied by diesel generators failed to come up. ATLAS was
quite fortunate and no serious damage was done. *But,* if such a
situation occurs when the experiment is fully operational it could
create serious problems.

**Abraham Seiden (UCSC)**

Work is continuing at a satisfactory rate in all areas. Very good
progress on 3-Dim. detectors, one of the key R&D projects. Other key
areas: staves, powering techniques, electronics technologies also
showing good progress.

**4.1.1 Detectors**

**Hartmut Sadrozinski (UCSC)**

All reported pixel activities concern 3D detectors produced at Stanford
U. Work on improvements of the yield is planned.

3D sensors irradiated with reactor neutrons up to 8.6x10^15^ n/cm^2^
were tested with an IR laser and satisfactory signals were seen.
Un-irradiated 3D pixel sensors bump-bonded to the ATLAS pixel readout
ASICs were tested in the H8 beam at CERN with scans of the bias voltage
and angle of incidence. The patterns of the sensor hits and their
location relative to the beam telescope hits was as expected.

University of New Mexico continued LCR meter-based 3D sensor capacitance
measurements on un-irradiated 3D sensors as a function of frequency. By
cooling the sensor to -20^o^ C the bias can be increased to 100V. Work
started on using TCAD for device simulations.

The work on detector technology covered the investigation of total
ionizing dose (TID) effects in short strips and test structures with a
^60^Co gamma source. Saturation of the surface effects is observed at
about 100 krad, with very large annealing of some effects. The breakdown
voltage increased dramatically with TID irradiation, especially for the
high p-spray dose, thus allowing the operation of the detectors beyond
depletion pre-rad and for neutron irradiation.

The charge collection efficiency measurement on irradiated p-type and
n-type MCz strip detectors was performed with our test set-up using a
beta source. At the proton fluence of about 3 x 10^14^ neq/cm^2^, the
two samples show very similar performance, since the low-resistivity n
MCz has not yet "undergone type inversion". This work will be repeated
using the SCT readout which is now working for positive and negative
pulses, and with detectors having been exposed to higher proton and
neutron fluences.

The short strip work covered mainly stripixels. Testing at INFN of
n-type stripixel is ongoing, and testing of p-type stripixels will
resume soon. Short strip detectors from Hamamatsu are expected in
early-mid October. Hamamatsu agreed to test up to 500 V. They will also
provide 5 mechanical samples for flatness and gluing tests.

**4.1.1.2 Investigation of Strip Technology**

**Hartmut Sadrozinski (UCSC)**

We continued our large-scale investigation of total dose effects on
silicon strip detectors (SSD) and test structures using a ^60^Co source.
The irradiation with a total dose of about 600 kRad supplied in several
steps was followed by three annealing steps of one week at room
temperature and two weeks each at ^60^Co. There is no difference between
Float Zone (FZ) and Magnetic Czochralski (MCz) bulk material, but a
large dependence on the surface treatment (p-spray dose). Saturation of
the flatband voltage and oxide charge is observed seen in all devices
after about 100 kRad. In addition, about 60% of the increase in oxide
charge annealed out after the first two anneal steps, after which it was
constant. The interstrip capacitance shows large bias voltage dependence
before radiation, which was much reduced after a dose of about 150 kRad,
but it did not exhibit annealing. The breakdown voltage increased
dramatically with TID irradiation, especially for the high p-spray dose,
but also showed large annealing. It allowed the detectors to be
depleted, which was not possible before TID irradiation (see below).

The charge collection efficiency measurement on irradiated p-type and
n-type MCz strip detectors was performed with our test set-up using a
beta source. The required temperature management to suppress the large
leakage current is well under control.

Several different strip detectors were tested pre-rad in preparation of
neutron irradiation at Louvain. The high dose p-spray detectors were
pre-irradiated with gammas in our 60Co source to permit operation beyond
depletion (see above).

A production review of the new 3 cm long detectors to be manufactured on
6\" wafers by Micron Semiconductors was held July 14, and production has
started.

The work on using the SCT readout for negative pulses has been finished
successfully and we are starting to work on hybrids in collaboration
with Prague and Freiburg. This will allow the readout of irradiated n-
and p-bulk detectors with the SCT readout which has 20 ns shaping time.

Motherboard from second vendor via INFN Milano are still in production.

Testing at IFNF of n-type stripixel is ongoing. At BNL, probe station
for pre-testing of stripixels is being upgraded and resumption of
pre-testing of p-type stripixels is expected in about a month.

Viking board purchase order placed in early July did not go out of BNL
until early September due to negotiations on terms and conditions
between BNL and Samina-SCI. Board is expected for delivery in mid
November.

At NYU, they are experimenting with a collimated laser mounted on an x-y
stage. Plans for integrating with Viking DAQ at BNL are beginning.

Hamamatsu detectors are still expected in early-mid October. Hamamatsu
agreed to guarantee currents up to 500 V, and to provide data up to that
voltage. They will also provide 5 mechanical samples for flatness and
glueing tests.

**4.1.2 Front-End Electronics**

**Alex Grillo (UCSC)**

The 0.13μm test chip containing ATLAS pixel analog front end circuits
and various types of memory cells was irradiated at the LBNL 88"
cyclotron with 50 MeV/c protons and 16 MeV/c light ions for SEU studies.
On the whole, the results are very promising up to maximum fluence thus
far tried, 1x 10^15^ p/cm^2^. See below for more details as well as SEU
results. The results were presented in LECC06, Valencia, 28-Sep.

There has been some progress this quarter with the SiGe evaluation but
not as much as was planned. Neutron irradiated parts have not yet been
returned for post-rad testing, proton irradiations at the CERN PS have
been delayed due to machine problems, and the gamma irradiations at BNL
have been progressing at a slower than expected rate. The demonstration
IC submitted to IHP in Germany for fabrication has been received and
testing is about to start. Also, a formal proposal was submitted to the
ATLAS Upgrade Steering Group for this SiGe evaluation work by a
collaboration of ATLAS institutions interested in both the Inner Tracker
and the LAr Calorimeter.

Test chip irradiation:

The 0.13μm test chip containing ATLAS pixel analog front end circuits
and various types of memory cells as irradiated at the LBNL 88"
cyclotron with 50 MeV/c protons and 16 MeV/c light ions for SEU studies.
The front end circuits perform well up to the highest dose achieved at
the moment, which is 1x10^15^ p/cm^2^. The linear energy transfer (LET)
thresholds have been measured for SEU in five different latch
structures. The cross coupled DICE type latches with custom geometry
proved to be the most tolerant, with single cell cross section limit
\<10^-11^ cm^2^ at the highest LET of 26 MEV/(mg/cm^2^). This is not
total surprise because the DICE architecture requires two simultaneous
signals on different nodes to change state, whereas LET from ions is
highly localized. Performance for high energy particles is expected to
be worse from first principles as well as FE-I3 experience, but these
tests have not been done yet. Collaboration with CPPM may possibly lead
to such tests at CERN this year. Triple redundant cells were also
studied, and for latched with measurable cross sections the upset rate
was well predicted by probability and the single latch cross section,
indicating no spatial correlation as expected for heavy ions. Results
were presented in LECC06, Valencia, 28-sept.

**4.1.2.2 SiGe for Strips**

**Alex Grillo (UCSC)**

By the end of September, we still had not received the parts irradiated
with neutrons at Ljubljana in January. This has been frustrating our
efforts to complete the evaluation of the SiGe technologies.
Furthermore, problems with the PS at CERN have delayed the irradiation
with protons. The neutron irradiated parts are now scheduled to be
shipped in early October. We hope this materializes. The RD50 facility
has been able to complete proton irradiation of a few parts at the
lowest fluences requested. The high fluence exposures should be
completed in October.

We did receive an offer to irradiate some parts at a neutron source in
Louvain, Belgium. This potentially could have advantages over the
Ljubljana reactor in that there is no addition of thermal neutrons and
the gamma background is expected to be much lower than with the reactor.
We sent two parts to Louvain in September for a try using this new
facility. If this works well, we will irradiate more parts in November.

There is not much new data on gamma irradiation at BNL. Partly this is
due to vacations and other distractions by the people at BNL, but there
has also been some confusion of the data files for electrical tests done
in July. We are in the process of sorting this out with the BNL people
and hope to resume these irradiation studies in October. It now appears
that all of the parts delivered to BNL for gamma irradiation will not be
completed until early December.

We were informed that IBM has added an 8WL SiGe technology along with
the 8HP to their 130 nm CMOS technology. The 8WL technology has somewhat
lower frequency performance but is also considerably cheaper. We have
been assured by CERN that both the 8WL and 8HP will be available through
the CERN/IBM frame contract. We will add the 8WL technology to our list
to be evaluated. Our collaborator at Georgia Tech, John Cressler, has
agreed to obtain some test parts for 8WL and make them available to us.

The demonstration IC on the IHP technology was fabricated and delivered
to us in late July. We have now produced a test board on which to mount
the IC and interface it to a Xylinx demonstration board and then to a
computer. Testing in this configuration will start in October.

We submitted a proposal to the ATLAS Upgrade Steering Group in June to
evaluate the various SiGe technologies for use in the upgraded ATLAS.
BNL, Penn, Barcelona and IN2P3 joined us in this proposal. At the end of
September, we were waiting for comments from the reviewers assigned by
the USG.

**4.1.3 Optical Readout**

**4.1.3.1 Diode Receivers**

**Flera Rizatdinova (Oklahoma State)**

We irradiated four PIN diode arrays from TrueLight as a part of
optoboards using 24 GeV proton beam at CERN. The integrated dosage was
70 MRad. All PIN diode arrays survived the irradiation. Responsivity of
PIN diodes was measured before and after irradiation. It has been found
that the responsivity of PIN diodes decreased by factor of 2 after
irradiation compared to the initial one. We expect to have a full
irradiated test setup in Oklahoma State University in a month.

**4.1.3.2 Fiber Drivers**

**K.K. Gan (Ohio State University)**

We irradiated four opto-boards with PIN and VCSEL arrays from various
vendors using 24 GeV protons at CERN. Each board was instrumented with
one silicon PIN array and a pair of GaAs VCSEL arrays. The PIN arrays
were all fabricated by one vendor, Truelight, and the VCSEL arrays were
fabricated by three vendors, Optowell, Advanced Optical Components, and
ULM Photonics (two varieties, 10 Gb/s and 5 Gb/s). On the opto-boards,
each of the PIN and VCSEL arrays coupled to radiation-hard ASICs
produced for the current pixel optical link, the DORIC (Digital Opto
Receiver Integrated Circuit) and VDC (VCSEL Driver Chip). Furthermore,
the opto-boards were mounted on a shuttle system which enabled us to
easily move in and out of the beam for annealing of the VCSEL arrays.

The test system consisted of four independent test boxes with each box
monitoring one opto-board. The test boxes could generate various signal
patterns, including pseudo-random data, and perform bit error rate
tests. The signal transmitted from the control room via optical fibers
to the PIN array on each opto-board was bi-phase mark encoded with a 40
MHz clock. Each PIN diode on an opto-board converted the optical signal
into an electrical signal which was then amplified and decoded by a
DORIC. The decoded clock and data were then routed to the VDCs which
drove the VCSEL arrays and produced optical signals for transmission via
optical fibers to the control room. Each test box then compared the sent
and received data to check for bit errors and monitored the power of the
incident light.

The test system was also used in the pre-irradiation characterization of
the VCSEL/PIN arrays and will be used for the post-irradiation
characterization after the opto-boards are returned to OSU with subdued
radioactive level. Two of the boxes will be given to our colleagues at
Oklahoma and Oklahoma State universities.

The test system monitored various parameters of the opto-boards
throughout the irradiation. Of particular interest was the optical power
of the VCSEL arrays vs. dosage. The power decreased during the
irradiation as expected. We annealed the arrays by moving the
opto-boards out of the beam and passing the maximum allowable current
through the arrays for several hours each day. The optical power
increased during the annealing. However, there was insufficient time for
a complete annealing. Consequently both the A.O.C. and ULM 5 Gb/s arrays
had no optical power at \~50 Mrad. The ULM 10 Gb/s arrays continued to
have optical power of more than 100 uW up to 65 Mrad and the Optowell
arrays survived up to at least 70 Mrad, the SLHC dosage. We believe that
more arrays would have survived if we had more time for annealing.

The silicon PIN arrays survived the irradiation quite well. After the
full SLHC dosage, their responsivity decreased to \~50% of the
pre-irradiation level.

In summary, a test system has been designed and fabricated that can be
used to monitor the opto-boards during the irradiation and for pre- and
post-irradiation characterization. A silicon PIN and GaAs VCSEL array
candidate have been identified to have radiation hardness suitable for
the SLHC operation.

**Jingbo Ye (Southern Methodist University)**

The proposed test on the GOL as the optical link transmitter side
serializer chip has two parts: the in-lab system test to characterize
this chip especially its behavior in an optical data link system in
terms of jitter transform and jitter contribution. There are other
issues like the power up schemes, bit error rates and optical power
budgets and sensitivities. The second part is the irradiation test to
probe the upper limit in terms of total dose that the GOL can withstand.

The test system with the GOL has been fully debugged in lab. Most part
of the jitter measurements have been carried out and GOL performs within
IEEE standard for similar data rate serializer chips. Power up schemes
have been checked. Bit error rates and sensitivities have been studied.

We are preparing for the irradiation test targeted in November. After
that test, a complete report will be generated in the form of ATLAS
note.

**4.1.3.4 Multiplexers and Interconnect Circuits**

**K.K. Gan (Ohio State University)**

Another important goal of the R&D program is to measure the bandwidth of
the infrastructure of the current pixel optical link. The two critical
components in the infrastructure are micro twisted-pair cables and fiber
ribbons. The former transmit the LVDS signals between the optical
components and the pixel modules. The latter transmit optical signals
between the optical components and the counting room. The fiber ribbons
consist of 8 m of radiation-hard, low bandwidth SIMM fibers fusion
spliced to 70 m of radiation tolerant, medium bandwidth GRIN fibers. At
the SLHC, we expect to transmit data at \~1 Gb/s, significantly more
than the current 80 Mb/s.

Our previous measurements indicate that the micro twisted-pair cable can
adequately transmit signals at 640 Mb/s and that transmission at 1,280
Mb/s might be acceptable. We have also previously measured the bandwidth
of a fiber ribbon consisting of 13 m of SIMM fiber fusion spliced to 16
m of GRIN fiber. To more closely resemble the fiber used in the current
pixel opto-link we repeated the measurement with a fiber ribbon
consisting of 8 m of SIMM fiber fusion spliced to 80 m of GRIN fiber.
The result indicates that the fiber can transmit signal up to at least 2
Gb/s. In summary, the current pixel opto-link infrastructure can
transmit signals at a speeds required by the SLHC.

**4.1.4 Modules**

**4.1.4.1 Stave Structures**

**Carl Haber (Lawrence Berkeley Laboratory)**

The stave development R&D proposal was submitted to ATLAS earlier this
year. Discussions were held with the upgrade steering group and the
referees. Some clarifications were added to the proposal as a result.

In this period lab work has focused on testing a stave with serial
powering. The serial power bus cable was received and checked out OK.
These bus cables were laminated to stave cores. A set of six serial
powered hybrids were mounted and bonded. All digital and analog
functions were as usual compared with individual power. A number of
modules were built with the existing sLHC hybrid and serial powering. In
the test box these work well. Mounting a serial powered module on the
stave, replacing one of the hybrids, shows good analog and digital
performance with noise and occupancy equivalent to off stave
measurements. One anomaly is a somewhat lower gain seen on the stave and
not yet understood. Work continues to add additional modules to the
stave.

A paper was presented at the recent Hiroshima meeting. A paper will be
presented 11/1 at the IEEE NSS and at the Liverpool upgrade meeting. A
workshop was held in Berkeley after the Hiroshima meeting to discuss
stave and other aspects of the tracker design. About 15 people, mostly
from Europe were in attendance.

Detailed design work has been proceeding towards an ATLAS specific stave
to be fabricated in 2007. A number of concepts are being addressed to
deal with both single and double effective layers.

**4.1.4.2 Hybrids**

**Carl Haber (Lawrence Berkeley Laboratory)**

A new hybrid layout was started aimed at the 2007 ATLAS specific stave.
The existing hybrid is 20 x 38 mm and holds 4 ABCD chips. The new hybrid
will be 13 x 60 mm and hold 6 ABCD chips with serial powering.

**4.1.4.3 Cooling Channels**

**Murdock Gilchriese (Lawrence Berkeley Laboratory)**

Stave Mechanics and Cooling

The conceptual design of a 1m long stave structure with integrated
cooling has mostly been completed by Innovative Technologies
International in collaboration with LBNL. The conceptual design, as
modeled, meets the following primary requirements:

Sag \<60 microns worst case

Delta T to silicon \<2^o^ C

Stability on cooldown \<15 microns (out of plane)

Radiation length \<0.8%(structure+coolant only)

Extensive FEA models of the mechanical properties have been analyzed to
understand the resultant sag from various assumptions. Thermal models
have also been completed to understand both the thermal performance at
temperature and the thermal induced strains. End connections have been
modeled in detail with various options.

The final design concept is composed of high modulus fiber facings, a
honeycomb core and a bent aluminum tube, slightly flattened in the
prototype design, thermally coupled to the facings. Specifications for
the fiber material and honeycomb have been developed. The tube will be
existing material used in the pixel detector to save money.

The emphasis of the work has now shifted to the design of tooling for
fabrication of prototypes. An initial fabrication sequence has been
defined and models of the tooling at various points in the fabrication
have been created.

**4.1.4.4 Powering Schemes**

**Carl Haber (Lawrence Berkeley Laboratory)**

We have focused on serial powering of actual staves, modules, and
hybrids. We have collaborated with RAL on this. RAL designed and
fabricated a serial powering pc board which works with the hybrid
developed at LBNL. Tests of this system show good analog and digital
performance including modules once the system is properly configured.
The AC coupling of non zero neutral COM lines is important here and
modifications to the circuit were made to handle this in a multi-drop
configuration.

The circuit is being adapted and integrated into a new serial powered
hybrid design for the 2007 ATLAS specific stave.

A serial powering bus cable for a fully loaded stave is being designed
as well. This should handle up to 30 modules.

**Maurice Garcia-Sciveres (Lawrence Berkeley Laboratory)**

A first prototype of a switch IC for a divide by 4 DC-DC charge pump
converter was fabricated with Austria Microsystems through CMP (France).
This chip allowed characterization of 50V HV MOS transistors in 0.35um
feature size and comparison to models. The relevant on-resistance for
this process was found to be 20% higher than the models (which means 20%
more silicon areas will be needed for the same current). Unfortunately
the chip cannot be used to produce a usable DC-DC converter because
parasitic transistors to the substrate create a current path to ground.
This was not predicted by the models initially used, but the design kit
has been updated since the submission and the new kit includes this
effect. An irradiation of these transistors is scheduled for Oct 17 at
the LBNL 88\" cyclotron. A new test chip is being designed that includes
clock drivers as well as switches with proper handling of parasitics.
The target submission date is Feb. 07.

**Note #1**  This turns out to be an ill-defined milestone, considering
our recent discoveries. While we certainly see the \"layer\" effect at
low electric fields, it now appears that we weren\'t seeing any layer
effect at and above the nominal field of 1 kV/mm. But we would like to
confirm this with the new sources.

**Note #2**  Based on the knowledge we learned from the two irradiation
tests, we decide to have two designs of the PLL block in order to
compare their behavior in radiation environment, and this require extra
time. The submission is decided by the foundry multi-project run
schedule and the one that is after Oct.-06 is Feb.-07.

**4.3.1 Layer Buildup due to Radiation**

**John Rutherfoord (University of Arizona)**

This LHC Upgrade R&D work is on small sections of FCal1 electrodes into
which strong Strontium 90 beta sources have been embedded. The strongest
source is 50 mCi and it will reproduce the ionization rate expected in
an FCal1 electrode at EM shower max at η = 4.7 at the design LHC
luminosity. The other electrode has a 2 mCi Strontium 90 source embedded
inside to provide a control. A third electrode has no source at all for
yet another type of control.

The cryogenic recirculation pump we ordered to improve the argon purity
was apparently delivered towards the end of July but we couldn't find
it. Not until last week did it finally show up in another office in the
physics building. In the meantime we've removed the BNL getter from our
apparatus to ship it to Protvino to help purify the argon for our test
beam run. It will take quite some time to reconstitute our purification
system since the Protvino tests are scheduled in small spurts into 2008.

We have asked the Russian power laboratory to laser weld one dummy
source ampoule so that we can assess the quality of the weld. We are
concerned about the surface roughness of the electrode rod in the
vicinity of the weld. And, of course, the quality of the seal will have
a bearing on the assessment of the safety of the source. For this test,
however, no source will be enclosed in the cavity. We can perform a
bubble test to see if there are any leaks.

The EGS simulation of the source inside the cavity in the electrode rod
was finally completed. The result gives the ratio of energy deposited in
the gap when the cavity is full of liquid argon to the case when the
cavity is evacuated to be almost exactly 0.700. We now have to make our
best estimate of this experimentally measured ratio for the two leaking
sources. But this simulated value is quite close to the measured value,
based on preliminary results.

Most of this quarter has been spent on preparations for our test beam
run at Protvino. One goal of this test is to measure the pulse shape
from the liquid argon gap as a function of the ionization rate.
According to my predictions the triangle pulse shortens quite a bit as
the rate goes well above the critical ionization rate. If this part of
the Protvino test goes well we should have a very nice measure of the
critical ionization rate which then gives the positive ion mobility.

Most of the costs of this test beam run at Protvino are being paid from
our M&O funds so I won't say much more about it in this report.

**4.3.2 Readout Electronics**

**4.3.2.3 Digital Readout System**

**Gustaaf Brooijmans (Columbia University (Nevis Laboratory))**

The receiver board needed for the test setup was built and debugged. It
can now operate in synchronization with the transmitter. The test setup
now has a transmitter board with an ALTERA Stratix GX FPGA which can be
programmed with fake ADC signals and implements the digital logic. The
data is sent to the receiver over the optical link at 3.3 Gbps. The
receiver then transmits the data to the PCI card in the PC where it is
transferred into the PC memory using DMA. This full chain is now
operational, although high rate or large data volume tests have not been
tried yet.

The PCI Express chip needed to upgrade our DAQ card from PCI to PCI
Express became available over the course of the summer and a new card
was designed. The design is complete and verified and fabrication has
started. To complete the test setup, and ADC board using a TI 8-channel
12-bit ADC has also been designed. This will be fabricated soon.

**4.3.2.4 Optical Data Link**

**Jingbo Ye (Southern Methodist University)**

TID test on the SOS 0.25 micron technology was carried out at BNL in
July and the result is positive: The test chips withstand 4 Mrad total
dose from a Co-60 source. After one month annealing, the chips recovered
to the range that are comparable to manufacturing process variations and
we conclude that this technology is suitable for upgrade of the LAr
readout. It may be able to withstand 100 Mrad total dose because the
leakage current and threshold voltage shifts all saturate after about
100 krad. More tests will be need to see if this technology is also
suitable for ID upgrade.

The SEE test is planned to be carried out in Boston with the proton
source from MGH. The targeted date is Nov. 4. The preparation for this
test is on-going.

The design of prototype LOC chip is progressing smoothly. We have
finished the PLL design based on the self-biasing technique. The design
for LC based PLL is in progress. The design of serializer and clock
distribution has been finished. The targeted submission date for LOCV1
is Feb. 07 according to Peregrine\'s foundry schedule.

**4.3.3 Trigger**

**4.3.4 Next Generation ROD**

**4.3.4.1 Next Generation ROD (BNL)**

**Hucheng Chen (Brookhaven National Laboratory)**

We started testing Xilinx FPGA with Xilinx ATCA PICMG Design Kit, which
includes one Xilinx FPGA-based ATCA 3.0 reference card and development
software. With this card we can evaluate the system performance of ATCA
platform, especially the serial data transfer rate on the backplane, we
can also test the RocketIO speed and DSP performance of embedded PPC 405
core in Xilinx Virtex-II FPGA.

Altera Transceiver Signal Integrity Development Kit was ordered, this
card has Stratix II GX FPGA, we will use it to test 6.375Gbps
transceiver, Stratix II GX is planned to used in the first version of
sub-ROD design. In the mean time, we are continuing the evaluation of
DSP performance of the Altera Starix II FPGA.

We started the design of the ROD-tester which will be used to inject
data to sub-ROD board collaborating with Univ. of Arizona, the
discussion of the feature and interface between ROD-tester and sub-ROD
is on-going.

**4.3.5 Radiation Hard Low Voltage Power Supplies**

**4.3.5.1 Radiation Hard Low Voltage Power Supplies (BNL)**

**Jim Kierstead (Brookhaven National Laboratory)**

Continuing with past efforts irradiation measurements of the factorized
Vicor product line continue. As reported earlier two of the Vicor
products which were irradiated to failure (50-60 krad) were returned to
the company. One of the products a 1.5 volt/90amp ( V048F015T090) had a
failure mechanism that was not clearly identified. The other was a
V048F015T090 (VTM module)/P048F048T24AL (PRM module) combination
operated at a modest load. The PRM module failed (was completely dead)
but again the failed component was not identified. The controller was
removed for further failure analysis. The VTM module was still
operational.

Two additional irradiations have been performed at a dose rate of 300
Gray/hour. The first was a PRM/VTM (4 volt, 50 amp output) loaded at
35 - 40 amps. The pair stopped working at a total dose of 520 - 530
Gray, inferring that the behavior in gamma irradiation is not load
dependent. In addition a Vicor BCM module was irradiated to failure
between 400-450 Grays. This module failed with a shorted input which had
not been observed before. Again both of these modules will be sent to
Vicor for failure analysis.

Also as reported earlier the switching MOSFETs for these modules were
supplied by Vicor on a separate test board. These devices were on
continuously and failed to switch at total doses of 3.5x10^4^ -4.5x10^4^
Gray. A test to characterize these devices more completely by switching
the gate/load during gamma irradiation at loads of 50 and 100% is
scheduled for this quarter. This might reveal a more limiting condition
if the threshold voltage changes affects the switching behavior at lower
total doses than indicated in the previous tests. Also beam time has
been reserved at Massachusetts General Hospital in December to measure
Single Event Effects on both packaged Vicor products and single MOSFETs.
Other products from other manufacturers will also be tested. This will
also indirectly provide information on neutron displacement damage.

**4.5 Muon Upgrade R&D**

**Abraham Seiden (UCSC)**

The purchase of the foreseen radiation monitors has been completed and
installation and cabling is in progress. This will continue, paced by
the actual installation of the Muon system itself.
