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

The emphasis in this quarter continued to be preparations for the
Computing System Commissioning (CSC) exercises which will start in early
2006. The ramp up in hardware and personnel begun last quarter continued
this quarter with new hardware ordered and scheduled for full deployment
in early 2006. All 3 Tier 2 centers also purchased new CPU and disks
this quarter for production operations in early 2006. All our facilities
continue to be available as part of the Open Science Grid.

The main software development effort was on the Production and
Distributed Analysis (PanDA) system. This is a new effort, using
existing experienced developers who were actively involved in our
successful Data Challenge 2 production system. The lessons learned from
DC2 were applied to the PanDA development and a PanDA prototype was
delivered on time this quarter following an aggressive schedule.

The area of Analysis Support (WBS 2.2.7) was added this quarter, managed
by Stephane Willocq. Its immediate responsibility will be to establish a
coherent Analysis Support Group that can provide the technical
expertise, analysis forums that can encourage performance/physics
discussions in U.S. and beefing up the Analysis Support Centers in
providing technical assistance to all U.S. institutes.

**Note #1**  Release 11.0.0 has been released. There are ongoing bug
fixes which will be completed by the end of the year. In addition, there
are minimal functionalities in Release 11.0.0 for use in commissioning.
More significant developments geared toward cosmic ray commissioning are
ongoing and a major release is expected in February-March 2006.

**Note #2**  Release 12 has been delayed to end of April with bug fixes
releases expected to come out in May 2006.

**Srini Rajagopalan (Brookhaven National Laboratory)**

The focus for the software development is the upcoming cosmic ray
commissioning and the computing system commissioning (CSC). The U.S. is
participating actively within these areas. Within the U.S., we have
reorganized ourselves with the approaching turn on to prepare ourselves
to provide optimal support to U.S. physicists.

From the experience gathered from Data Challenge 2 (DC2) exercises, the
U.S. has reorganized itself in the area of production and distributed
analysis. A new Level 3 organization has been created with Torre Wenaus
as its manager. Given the importance of data management, production and
distributed analysis using U.S. grid and computing resources, the U.S.
distributed software team has come up with a new design for the
production and distributed software. This new design addresses the
shortcomings and failure observed in DC2 and brings together the
software for production and distributed analysis. A prototype has been
tested and delivered in December 2005 and a full scale system is
expected to be deployed for the upcoming ATLAS CSC.

The application software (renumbered to WBS 2.2.5) has been reorganized.
It reflects the research program funded effort in the area of tracking,
calorimeter, muons and other core application software. The emphasis on
these kernel application software reflects the importance of
establishing a solid foundation to build the U.S. physics analysis
effort. We have also merged the Generator effort into Application
software - Generator in previous WBS appearing under \"Physics\".

The area of Analysis Support has now been established. With the outcome
of a task force recommending a model to support U.S. based analysis, we
have established a Level 3 organization on Analysis Support (2.2.7).
This area is managed by Stephane Willocq (U. Mass, Amherst). Its
immediate responsibility will be to establish a coherent Analysis
Support Group that can provide the technical expertise, analysis forums
that can encourage performance/physics discussions in U.S. and beefing
up the Analysis Support Centers in providing technical assistance to all
U.S. institutes.

**Note #1**  This is still an important item. However this semester we
have been mostly busy with preparing the misaligned LAr calorimeter AND
in fact helping everybody in the LAr get ready to use this in
simulation. And so this has been delayed.

**Joe Boudreau (University of Pittsburgh)**

The last quarter of 2005 was mostly spent preparing the realistic
detector LAr detector description (adding misalignments material), and
resolving clashes; also preparing and debugging the first run of full
simulation with a geomodelized LAr. Restoring the functionality of
calibration hits in the geomodelized simulation took a lot of our time.
Vakho was especially active in these areas. This delayed the completion
of the identifier==\> oracle db milestone.

**2.2.3 Data Management**

**David Malon (ANL)**

The database WBS area reflects some reorganization in support of the
distributed software effort; for example, some milestones that were
previously categorized as \"common data management software\" are now
explicitly listed as \"distributed data management.\"

This WBS area remains 1 FTE below planned U.S. staffing levels.

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

**Note #2**  Cross-type conversion is possible via the
transient/persistent separation machinery. A more ambitious mechanism
should be added to the milestone list.

**Note #3**  December 2006: 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.

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

**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 2006: This milestone must be delayed until some time after the
corresponding control framework history infrastructure is in place.

**Note #2**  Initial performance tuning is complete, but yielded a
speedup of only 20%. A more extensive program of optimization will be
undertaken after transient/persistent separation of the event data model
is in place.

**Note #3**  December 2006: Processing stage specification as an
OutStream property has been added to ATLAS releases. The corresponding
scope-based retrieval machinery is being redesigned in the context of
the ATLAS Architecture Team, and should get a new milestone in spring
2006.

**Note #1**  Panda successfully implemented in DIAL as a processing back

**Torre Wenaus (Brookhaven National Laboratory)**

During the quarter the distributed analysis effort was focused in a new
direction \-- Panda \-- as part of the overall reorganization of
distributed software in US ATLAS. The Panda project was initiated in the
last quarter to develop a distributed processing system handling the
full spectrum of usages from managed large scale production to
individual job submission and interactive distributed analysis. During
the quarter there were two principal objectives for distributed
analysis: 1) Develop a distributed analysis service based on direct
injection of analysis work to Panda, and 2) integrate DIAL with Panda
and evaluate how Panda can leverage DIAL. The first objective was met
with the development of pathena, a command line tool following the style
of command line invocation of Athena, but submitting the Athena job to
Panda with inputs and outputs specified via DDM datasets. The second
objective had two parts: first and foremost to implement Panda as a
processing back end behind the DIAL interactive analysis environment,
and secondly to implement a prototype of hierarchical job management
within Panda using DIAL\'s job hierarchy. The first objective was met,
and the second not. Panda effort was heavily focused on bringing it into
production and there was not enough time (or priority) to implement the
job hierarchy prototype. Both the pathena and DIAL analysis front ends
to Panda were functional but job turnaround was too slow due to long
latency for job start while the Panda system was saturated with
production jobs (as it always was). Strategies were in development at
the end of the quarter to address this problem in the next quarter.

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

**Note #1**  Panda successfully integrated as an ATLAS production system
executor via the ExInt interface to the Eowyn supervisor.

**Torre Wenaus (Brookhaven National Laboratory)**

During the period the Panda distributed production/analysis system was
developed from a first proof-of-principle prototype to a deployed
production tool that took over ATLAS production in the US in December.
The first prototype deployed in September had first implementations of
all major components, DQ2 integration, and was able to process test
jobs. The mid-October milestone was to add integration of ATLAS prodsys
(an interface to the Eowyn supervisor), and process real ATLAS jobs.
This milestone was met on time. The mid-November milestone was to have
Panda operating smoothly for ATLAS production processing, which was met
as well. Panda ran in pre-production mode in parallel with US ATLAS
production based on the old Capone executor system. The most important
milestone of the period was to have Panda take over full responsibility
for production by mid-December, and this too was met. By early December
Panda was debugged and validated for production, and it took over from
Capone shortly thereafter.

**2.2.4.3 Production Support**

**Torre Wenaus (Brookhaven National Laboratory)**

Production support activity during the quarter consisted of direct
participation by all distributed software personnel in the operation and
debugging of the distributed software systems used in production during
the quarter: Panda, DDM/DQ2, pathena, DIAL, and ancillary tools and
services.

Several bug fixes have been applied to the main event generators, Pythia
and Herwig. ATLAS is using a patched version of both Pythia and Herwig
as the authors could not release a version in time. Software tools have
been developed, mostly focusing on testing and validating the physics
consistency of the HepMC event structure. These tools are heavily used
for the ATLAS CSC event generation.

The basic infrastructure to import events generated by Sherpa into the
ATLAS detector simulation/reconstruction was put in place. The
ATLAS/AlpGen interface was updated to the latest version of the latter.
Extensive interactions with the ATLAS user community took place as bugs
were reported, diagnosed and fixed in various packages as McAtNlo,
Comphep and Generator Modules. Several job submission scripts and the
necessary job options were developed, used for the production of the
generated event samples, as they are defined by the CSC project.

For the Oct-Dec quarter, Moyse mainly worked on the Muon Event Data
Model, in particular ensuring that it could be persisified, and that it
contained the required information. Moyse started work on cleaning some
aspects of the Muon CVS repository, and also did general maintenance to
keep Muon reconstruction working. Additionally, work started on new
mechanisms to handle \"schema evolution\" within the ATLAS EDM, and
Moyse represented the Tracking community in these discussions. Moyse
helped start the migration of MOORE to the new tracking EDM.

**Frederic Luehring (Indiana University)**

Research by Haleh Hadavand began Sep. 2005 to develop software on the
ATLAS Gatherer which is designed to facilitate distributed monitoring of

HLT data. Early work involved learning the tools available from 2004
test-beam and modifying them so that they would compile and run with
late 2005 HLT and tdaq releases. A first running and fairly stable
version was accomplished by year-end. Work also began during this period
to understand how to employ the full set of TDAQ tools to run actual
online monitoring irrespective of the Gatherer. The Gatherer work was
geared toward a fully usable and released version for May 2006. The
other online work was geared towards performing online monitoring during
Winter Commissioning periods.

**Alexander Undrus (Brookhaven National Laboratory)**

In this quarter NICOS, control system of ATLAS nightly builds,
successfully supported standard monolithic and experimental
project-oriented nightly builds. In project oriented nightly builds
ATLAS software was split into eight projects. NICOS ensured proper
synchronization of project builds according to their hierarchy. The
status of project builds (with number of failed compilations and tests)
was reflected on the summary NICOS web page so the ATLAS software The
nightly builds were checked with about 70 unit and integration tests
performed in the ATN testing framework integrated with NICOS. At BNL new
ATLAS software releases were promptly installed, usually in one to two
days after CERN installation. The mirrors of ATLAS CVS repository and
ATLAS nightly builds were supported. The LXR server,
alxr.usatlas.bnl.gov, provided the collaboration-wide service for fast
searches of ATLAS software.

During the period Oct-Dec 2005, a chair was selected for the Analysis
Support Group and several discussions took place within the US ATLAS
Collaboration to define the implementation of the analysis support
model. The current model includes an Analysis Support Group consisting
of \'on-call\' software and detector performance experts, a set of three
Analysis Support Centers (ANL, BNL, LBNL), and a series of Analysis
Forums for discussion of analysis development, issues, etc. A Beyond the
Standard Model workshop + ATLAS software tutorial to be held at LBNL in
Jan 2006 was in the planning phase.

**3.1 Subsystem Manager\'s Summary**

**Alex Grillo (UCSC)**

Pixel pre-operations activities have started, focused on preparation for
10% system test at CERN. The prototype service quarter panel under
construction at LBL will be used in this system test. Additional
electrical tests are being performed on this panel in preparation for
this. Maintenance activities include building of spare components.

The SCT four-barrel assembly is complete and ready for insertion into
the TRT. This insertion has been delayed until Jan-06 because of leaks
in the TRT gas manifolds. Cable assembly, testing and installation
continues. Other issues regarding systems electrical engineering are
being worked as they arise.

The spare RODs have been fabricated and testing has started. The B-layer
crates for Pixels have been ordered.

Activities at CERN

A set of dummy Type 1 cables has been requested to be able to connect
power to prototype sectors and staves before the service prototype
service quarter panel is shipped to CERN.

Prototype service quarter panel has been tested electrically by
sequentially operating a module through each of the panel connectors.

**3.1.1.3 Maintenance**

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

Hot Module spares

12 bare modules have been requested from the pixel collaboration for a
supplemental production of disk modules. This action has been started in
response to degradation of modules loaded on 2 sectors, which caused the
sectors to be qualified as spares. It is now desirable to have at least
one more high quality sector to complete the 6th disk. This is a
production of additional spares.

**3.1.2 SCT**

**Alex Grillo (UCSC)**

The four-barrel assembly is complete and ready for insertion into the
TRT. This insertion has been delayed until Jan-06 because of leaks in
the TRT gas manifolds.

Cable assembly, testing and installation continues and will continue
well into the Spring.

Other issues regarding systems electrical engineering are being worked
as they arise.

**Note #1**  The schedule for pre-operations testing at CERN is running
well. All four barrels have been delivered to CERN but they were delayed
relative to the original schedule. The four barrels have also been
assembled together, however, with the slip in delivery schedule of
barrels, the testing of all four barrels together has been dropped until
after integration with the TRT.

**Note #2**  Integration of the SCT barrel with the TRT has been delayed
due to leaks in the TRT gas lines. Integration is now expected for
Jan-06. Operations of barrel SCT and barrel TRT should be well underway
by end of Feb-06. This is still consistent with the schedule for
installation in UX15.

**Note #3**  This is the new ATLAS schedule for installation of the ID
barrel into UX15

**Alex Grillo (UCSC)**

The integration of all four barrels was completed in October. Cooling
services were connected to the pipes on each barrel and two small leaks
were found at the connection points. These were fixed with epoxy. The
four-barrel assembly is now ready for insertion into the TRT barrel,
however, this has been delayed until Jan-06 due to leaks in the TRT gas
manifolds, which are now being re-built.

Preparations are underway for cosmic rays tests with the combined SCT
and TRT barrel as soon as the integration of the two systems is
complete. Sofia is taking an active role in this work.

Sofia and Forest continue to share in the work of testing of power
cables. This activity is expected to continue well into the spring.
Sandra Ciocio from LBNL is supervising the entire cable testing and
installation work at CERN. Cable assembly (i.e. cutting cables to length
and mounting connectors) continues to be a problem. The latest is beaks
in the insulation of the large conductors at the point where they are
bent to fit into the connector hoods. This is being investigated by a
group from CERN, Prague and the US. It is clear that there is a
manufacturing problem with cable but replacing the faulty cable is not
consistent with the installation schedule. Other possible solutions are
being investigated, but even this is delaying the installation schedule.

Melbourne and Krakow sent technical staff and students to complete
testing of the power supply backplanes. Sofia had modified the PVSS
software and dummy load boards so that this testing could be
accomplished efficiently. She helped with the testing, which was
completed for all backplanes except the ones being used at Liverpool and
NIKHEF for disk assembly testing. These nine backplanes will have to be
tested later once they are returned to CERN. Fortunately, the rather
high failure rate we had seen on the few backplanes tested earlier in
the year, did not continue and only one new failure was found.

Ned evaluated the connectivity of the metal shielding of barrel Outer
Thermal Enclosure to the Heat Spreader Plates and PP1 support plates and
found the construction adequate. Also, modifications were made to the
end-cap PP1 assembly design.

## 3.2 M&O TRT {#mo-trt .unnumbered}

**3.2 Subsystem Manager\'s Summary**

**Harold Ogren (Indiana University)**

During this period of the research program we focused on electronics
testing and cosmic ray testing and the preparation of the TRT barrel for
integration with the SCT. We also redesigned large parts of the cooling
and active gas system due to a number of leaks that were found after the
initial mounting of the services.

Services Manifolds:

The distribution system for the cooling liquid (Fluorinert) was made of
brazed stainless steel. This was used because it gave us a strong,
selfsupporting system that was thought to be durable for the life time
of the experiment. This stainless steel distribution system then
connected to the modules with Peek tubes. After passing many pressure
tests, and after mounting the system, several of the brazed joints began
to leak. It is thought that this had to do with the slow removal of
brazing flux during the cleaning and testing process that exposed gaps
in the brazing. After removing and examining all the manifolds, we
decided to replace the stainless steel with Peek for the entire
manifold. The new \"spines\" were redesigned by groups at CERN and
Indiana University, and by the end of December all Peek parts were
completed and a complete prototype of a spine had been attached to the
TRT barrel and successfully tested.

Electronics testing- Cosmic ray testing:

During this period we reverified all the barrel electronics and set up
to run cosmic events through the top six modules and three of the lower
modules. These events have been used to tune the on-line monitoring
tools, measure cross-talk and other instrumental effects. Completing the
\"byte stream converter\" for this task proved much more time consuming
than originally estimated because of the complexity of the barrel straw
mapping.

**3.2.1.1 TRT Pre-Operations**

**3.2.1.1.4 TRT-6 mod-check**

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

During this period Ben LeGeyt and Mike Hance reverified all the barrel
electronics (finding a few fuse problems and one not so minor plumbing
leak) and set up to run cosmic events through the top six modules and
three of the lower modules. These events have been used to tune the
on-line monitoring tools, measure cross-talk and other instrumental
effects, and make lots of really pretty pictures for the group as a
whole. The downside of this effort was that many people looking at
off-line tools began demanding this data in the standard off-line
format. Completing the \"byte stream converter\" for this task proved
much more time consuming than originally estimated because of the
interesting complexity of the barrel straw mapping. It is clear that the
off-line troops really did want the data as off-line displays of SR
cosmics appeared within six hours of Paul Keener\'s release of the
completed byte stream converter.

**Harold Ogren (Indiana University)**

The TRT was being made ready for the joining of the SCT during this
period. Kirill Egorov was working fulltime on repairing the cooling and
active gas manifold to make it ready for the joining of the two in
February, 2006. This consisted of testing the Peek manifolds for gas and
liquid leaks, and constructing the newly designed units.

**3.2.1.1.5 TRT-SCT in SR**

**Harold Ogren (Indiana University)**

During this period we redesigned the services manifolds for the active
gas and the cooling. Curt Baxter redrew the layout for the new Peek
manifolds, and the Indiana machine shop machined the templates for
bending the new Peek distribution lines. Bryan Martin completed the
production of Peek components for the 16 Spine manifolds for each side
of the detector. Work was completed on Jan 2, 2006.

**3.2.2 Common TRT/ID**

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

**Ryszard Stroynowski (Southern Methodist University)**

All barrel Front End Boards are produced, tested and shipped to CERN.
Most of them have been installed into the crates on the barrel cryostat.
The commissioning of the crates started in Summer 2005 and is proceeding
very slowly. The crates power supplies and cooling have not been
connected, thus temporary, portable cooling system and temporary power
supplies have to be used. At the end of December only 10 crates have
been fully commissioned.

About 15% of the Front End Boards have some sort of problem. These
boards are pulled out and replacement boards are put in, so the
commissioned crate has a complete set of boards with all channels fully
functional. The problem boards are collected and will be repaired in
Spring 2006. The problems range from warped PCB boards due to uneven
stress of the mounted cooling plates, to malfunctioning preamps, shapers
or other components.

The commissioning is further slowed down by cabling campaigns limiting
access to the detector. In November a badly inserted screw for mounting
of the inner detector services generated loss of independent groundings
between barrel and tile cryostats. Since the performance of electronics
(noise) depends on this ground, all commissioning and installation work
was stopped for several weeks until the culprit was found and repaired
in December.

The precommissioning of the low voltage power supplies encountered
several problems and uncovered a design flaw that has to be fixed before
mounting of the units on the detector. The symptoms included cracking of
the capacitors and breakdown of the inductors on some of the boards
inside the power supply. Extensive design reviews and tests performed at
BNL traced the problem to excessive heat generated on the boards. Design
changes have been suggested and the negotiations with MDI company for
repairs of all the units (including those that are already mounted on
the cryostat) have been initiated. Power supplies are now on the
critical path for the completion of the LAr detector commissioning. The
repairs are expected to be completed by June 2006.

The analysis of the FCal test data showed several surprises, described
in the accompanying text. Endcap C has been lowered down to the pit and
its integration with extended tile barrel has started. Endcap A is
transported to the Point 1 and will be lowered down to the pit in March.

Most of the cryogenics work was concentrated on the installation of cryo
lines on the detector and connections of these lines to the
refrigerators and pumping stations. The transition to the UNICOS
software is schedule for February.

The preparations for the high intensity beam test to check the
performance of the Liquid Argon calorimeter in very intense radiation
(FCal region) have started in Arizona. Technical run is scheduled for
summer 2006 at CERN and full intensity beam test will take place in
November 2006 at Protvino.

**3.3.1.1 Pre-Operations and Commissioning**

**John Rutherford (University of Arizona)**

In June of 2005 Rutherford and undergraduate student Brokk Toggerson set
up and ran tests on the FCal warm electronics in the EMF at Point 1.
This was the same warm electronics used in part of the FCalC cold
commissioning in Building 180 in March. Critical help came from Stefan
Simion, Henrik Wilkens, Luis Hervas, John Parsons, and, in separate
tests of the level 1 trigger path, from Vittorio Paoloni and Bill
Cleland. Our run plan was developed in collaboration with Alexandre
Savine. One goal was to determine the input impedance of the preamps by
plugging precision resistor banks into the baseplane connectors where
the pedestal cables normally go. The pigtails have characteristic
impedance of 25 Ohms so looking backwards from the preamp input, one
should see approximately 25 Ohms. We used resistor banks of 15 Ohms, 25
Ohms, and 62 Ohms and took calibration data, watching how the preamp
output (through the shaper) changed with these precision resistors at
the input. Preliminary results show that the preamp input impedance
tends to be larger than 25 Ohms, some as high as 27 to 28 Ohms. Coupled
with earlier measurements of the pigtail impedance via the TDR which
showed some pigtails with characteristic impedance well below 25 Ohms
there is the potential for rather large impedance mismatch, of order 4
to 5 Ohms. We observed rather large reflections in the region of the
feedthrough during our FCal Calibration test beam run in 2003 and during
the Combined EMEC/HEC/FCal test beam run in 2004 and this easily
explains the cause. For that 2003 test beam run we were short one
pigtail (of 64 coax lines) so Victoria gave us an extra. It is
comforting that this pigtail had characteristic impedance quite close to
the nominal 25 Ohms. So we hope the impedance mismatch in ATLAS will be
smaller than in this test beam run where the rest of the pigtails were
purchased by Arizona from batches produced by Axon before the production
run.

A number of problems showed up during the EMF tests. We thought the
earlier problems with the calibration pulser had been fixed. (The
calibration pulse rise time was so sharp that slew-rate limitations in
the preamp led to non-linearities. We thought these were fixed when we
attached 150 pF capacitors across the 50 Ohm output resistor on the
pulser to slow the rise-time.) But non-linearities, at least as bad as
we had seen earlier, showed up again in the data we took in the EMF.
After the June tests we sent the calibration pulser board back to Orsay
along with the FCal baseplane. There it was discovered that all the
pulsers, not just the FCal pulser, were subject to an instability. A
work-around was found for this instability using a feature on the mother
boards introduced for the FCal and Orsay now believes the pulsers,
including the FCal ones, will work fine. Our next opportunity to test
this is in the cavern when the final warm electronics is installed.

Further analysis of the EMF data at Arizona showed up another surprise.
The rad-hard ADCs on the FEB, first used on the production boards, have
a large differential non-linearity. We see spikes in the noise and
calibration spectra which, only after a lot of effort, we were able to
trace to the ADCs. Some ADC bins are half as wide as the nominal and
others 40% wider than the nominal. We even traced down which bins were
the bad ones and the patterns make sense when the technology of the ADC
is taken into account. While it is discomforting to see spikes and
narrow valleys in the noise spectra, this differential non-linearity
probably has negligible effect on any measurement of concern to us. We
have spent some time to see if there are diabolical cases where this
could be a problem and haven't found any so far.

The cold commissioning of the FCalA took place in Building 180 in
September and the results were analyzed in this quarter. We found a few
of the usual problems at the expected low level. But one big problem
showed up as well. While filling the EndCap A cryostat with liquid argon
a short developed on one of the FCal3A summing boards which took down an
entire HV channel feeding about 57 readout channels. In the design of
the summing boards we had foreseen a possibility that we would lose an
HV channel so we distributed the HV in such a way that the affected
readout channels are not clustered together. In this particular case one
quarter of the readout channels in one quadrant of FCal3A are dead as a
result of this HV short. None of these channels are adjacent and are
rather uniformly distributed in a checkerboard pattern throughout the
quadrant. So a software correction should be quite effective.
Nevertheless we are hoping to fix the problem. First we expected that
whatever created the short might float away when the liquid argon was
emptied after the cold commissioning. But it didn't. Next we hope that
the supposed debris might fall away in the jostling during transport
from Building 180 to Point 1. This transport happened late in January
and testing is scheduled for early February. So we don't know the answer
yet. But we have prepared for the worst. We have constructed a device to
introduce short electrical pulses down the HV lines in hopes of burning
the debris off the board. And we have done extensive testing using a
spare summing board to determine the limits where we might do permanent
damage to the summing board itself. It is certainly possible that the
debris is so robust that it can carry the current in our pulse without
evaporating. In that event we will be stuck with this failure and will
be forced to implement software corrections.

There is good progress on the test bench for the FCal electronics chain.
Four readout channels, each with three gains, are being constructed. The
part of the warm electronics which takes the ADC data into a digital
pipeline and then reads it out to the online computer has been
completed. Also a test board which outputs patterns to simulate the ADC
output has been produced. Testing should start in January. It is hoped
to have the analog parts finished and ready for testing in early Spring.
It is possible that others in the liquid argon community will find our
scheme useful for small-scale tests and that we will be providing this
warm electronics to other groups once it's utility proven.

In summer 2005 it was discovered that there was a problem with the
geometry description of the FCal1 in the simulation, and perhaps in the
analysis code. We have had several rounds of discussion within a fairly
wide community and, as a result, several other problems and
inconsistencies in the geometry were discovered and fixed. (None of
these problems are in the hardware or in our description of the
hardware, but in the descriptions in the standard ATLAS software.) But
some problems or disagreements still remain. We take this as very
productive because we expect that, when the dust settles, we will have
enhanced confidence in the mapping of the FCal channels from the
physical electrodes to deep within the ATHENA code.

Half of the 32 crates on the EMBarrel have been pre-tested using the
temporary DAQ system. The first FE crate to BE crate connection using
the final cables has been performed, and will be used during the Expert
Week in January.

Equipping and testing of the 54 HEC FEBs is proceeding smoothly.

The setup at Nevis of the test system and environmental chamber to be
used for FEB lifetime testing was completed. This test will get underway
in spring, after the pre-production FEBs to be used are shipped back
from CERN.

**Francesco Lanni (Brookhaven National Laboratory)**

Final commissioning of the receiver system require the installation of
the FEC\'s and the final trigger cables completed and connected.
Presently testing of the trigger paths are done with the same set of
receivers and completed trigger cables.

All receivers are shipped to CERN and installed in their crates.

A problem was found in the transition boards for all detectors other
than the barrel. The trigger cable ground for one input cable for the
receiver (4 trigger cables/per receiver are installed) has been found to
be connected to the receiver ground. A possible solution has been
determined and will be done at CERN (i.e. no need to ship these
transition boards back to Pittsburgh).

Approximately half of the 32 crates of EMBarrel readout electronics have
been pre-commissioned using a standalone test setup. Work has re-started
after a break of several weeks during the move of the cryostat to its
final position around the IP. The first of the final connections from
Frontend to Backend electronics is being made, in anticipation of an
Expert Week planned for late January.

The HEC FEBs underwent testing and pre-ops using a dedicated setup in
B180 developed for this purpose.

In parallel, work continues at Nevis to set up the environmental chamber
and test system that will be used to perform the longterm lifetime test
of the FEB.

Pre-commissioning of 8 LVPS installed on the EMBarrel completed. It was
decided to install and temporarily commissioning 8 LVPS to allow for a
smooth installation of the Front-End readout electronics while awaiting
retro-fitting the LVPS in production.

Installation and phase-1 commissioning of the Crate Monitoring system
(FEC-DCS) completed. DCS software development and integration in Atlas
DCS in progress (D. Damazio).

Commissioning of standalone minimal cooling system at CERN completed.

**John Rutherford (University of Arizona)**

In the design phase of the liquid argon calorimeters each of the
sub-systems conducted radiation testing on the components to certify
that they would survive 10+ years of exposure and would not poison the
liquid argon. But for the FCal it wasn't possible to find a facility
which could provide the equivalent of 10 years of exposure because the
FCal is in such an extreme radiation environment compared to the other
calorimeter systems. During early LHC upgrade meetings it was proposed
to conduct a test at Protvino on their 70 GeV proton accelerator.
Arizona realized that this would be an opportunity to conduct definitive
tests on the FCal for the full luminosity of the nominal LHC as well as
the upgraded LHC. For this Protvino test we have designed a small
version of the FCal1 module dubbed the FCalchik. The Russian suffix
implies the diminutive. Half of the module has the conventional
electrodes and the other half beside it has 100 micron gaps (2.5 times
smaller than the nominal). So by moving the cryostat sideways we can
direct the beam onto either the model of the existing FCal1 or onto a
version better suited to the upgraded LHC. It is planned to have a
technical run at CERN in the summer of 2006 and a first run at Protvino
in November 2006, if the accelerator schedule allows. At Protvino, two
types of tests are foreseen separately on the model of the EMEC, the
HEC, and the FCal. The first test would run the beam at an intensity to
match what will be seen in the worst position in the module at the
upgraded LHC. The second type of test would be to run the beam at such a
high intensity that we could match the integrated exposure seen in 5
years of running at the upgraded LHC in one week at Protvino. This
latter type of test presents a number of severe challenges, particularly
for the FCal. Foremost among these is cooling. The heat deposited in the
FCalchik will be so large that special cooling features will be
required. We have designed cooling channels into the FCalchik through
which we intend to flow liquid nitrogen. This then confounds the usual
methods used to regulate the temperature inside the cryostat so we will
have to pioneer modified techniques. We plan tests at Arizona to develop
a stable method for this regulation. Another severe challenge is to
provide the HV current to the electrodes. This seems so far removed from
the realm of reason (several amps) that our fall back position is to
turn the HV down so far that currents in the range of tens of milliamps
are drawn. So the interpretation of the long-term testing of the
FCalchik will be compromised by this limitation. A few lesser challenges
can probably be overcome. It is worth pointing out that this test will
be pushing the limits of liquid argon calorimetry in a direction that
could prove useful at future hadron colliders, should we succeed. We
also hope to test some of the predictions of the positive ion buildup
calculations.

We have started a big push to get out publications on past test beam
runs. A long paper on our 1998 tests of our engineering prototype is
nearly ready for review within the FCal community. And we have organized
a month-long workshop at Arizona in March 2006 where we hope to finish
off some of the analyses of the 2003 Calibration test beam run of the
FCalC modules. In preparation for this workshop we are conducting
bi-weekly conference calls during which we have been defining acceptable
analysis procedures.

## 3.4 M&O Tile {#mo-tile .unnumbered}

**3.4 Subsystem Manager\'s Summary** **Larry Price (Argonne National
Laboratory)**

This period saw the completion of stand-alone (Mobi-Dick) certification
of drawers before the start of certification by sectors of eight
modules. Sector certification was started in late November, discovering
some additional individual faults in drawers, necessitating repairs, but
also revealing problems in the operation of the low voltage power supply
that needs further investigation. In addition, it remains the case that
electrical noise from the low voltage power supplies is compromising the
performance of the TileCal readout. Work is in progress to understand
and remove this noise but production is continuing with the present
performance. The DAQ software for the drawer at Chicago was updated to
make its maintenance easier and functioning more effective. A set of 45
repaired 3in1 cards was tested with the revised system and shipped to
CERN. Much work was done on testing and validation of cables and fibers
both before and after installation by Technical Coordination. The
cryostat and MBTS (Minimum Bias Trigger Scintillator) counters were
fabricated, tested and shipped to CERN for installation. Numerous tests
were conducted on the MBTS prototypes and the design was altered in
order to increase the light yield. A detailed plan was developed for the
installation effort for all of the scintillation counters in 2006. The
forward moderator plates (boronated polyethylene) were machined and
shipped to CERN for installation in 2006. Data were entered in the CERN
MTF (Material Tracking Folders) system documenting the Tilecal
components installed underground. Database software was prepared for the
onset of module by module commissioning toward the end of the period.
ITC pre-installation work is completed. Post-installation work will take
place in the next quarter. Progress was made in planning ITC
scintillator calibration.

**3.4.1.1 Pre-Operations** **Joey Huston (Michigan State University)**

Work on ATLAS M&O proceeded at both Michigan State University and at
CERN for the period of October 2005 through December 2005. The technical
staff involved were Mike Nila (senior technician) and Ron Richards
(engineer/designer) and the physicists were Joey Huston and Bob Miller.
Ron Richards made 2 trips to CERN during this time period with each trip
lasting 2-3 weeks. While at CERN, Ron installed light covers for the
TileCal modules and installed vapor liners (fabricated at MSU) between
the barrel and forward liquid Argon calorimeters and the TileCal
calorimeters. He also drilled and tapped mounting holes for the cryostat
scintillators as well as preparing EBA and EBC for their transport into
the pit.

At MSU, the cryostat and MBTS (Minimum Bias Trigger Scintillator)
counters were fabricated, tested and shipped to CERN for installation.
Numerous tests were conducted on the MBTS prototypes and the design was
altered in order to increase the light yield. A detailed plan was
developed for the installation effort for all of the scintillation
counters in 2006. The forward moderator plates (boronated polyethylene)
were machined and shipped to CERN for installation in 2006.

**Larry Price (Argonne National Laboratory)**

Data were entered in the CERN MTF (Material Tracking Folders) system
documenting the Tilecal components installed underground. Database
software was prepared for the onset of module by module commissioning
toward the end of the period.

Module by module commissioning began in the latter part of November.
Faults were found in about 15% of the drawers tested. Leon Reed from
Argonne was joined the Clermont group on the team making repairs to
drawers. Detailed diagnosis was made with the portable DAQ system
(Mobi-Dick), which was also used to determine drawer performance after
repairs were made and before repeating the official commissioning
process. Difficulties were discovered in the operation of the low
voltage power supplies during the initial steps in commissioning and
these are being investigated. Use of COOL and other databases was
exercised during the early commissioning runs. The chain of programs was
further exercised by using performance monitoring code in Athena.

Technicians commuting from Argonne worked on testing and validation of
cables both before and after installation by Technical Coordination.
Samples of new trigger cables were received and tested. Two expert weeks
were held during this period to advance specific aspects of readiness
for commissioning.

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

Dave Forshier - one of our UIUC technicians continued to work full-time
at CERN along with other TileCal technicians on installation & the
cabling up & testing of ATLAS TileCal, under the daily supervision of
Bob Stanek & Irene Vichou. He came back to the U.S. in mid-November,
after working at CERN for 3 months.

Irene continued with her work at CERN, as the coordinator of the
Services Installation and testing. She is responsible for the generation
and up-to-date maintenance of the cabling database for TileCal (Oracle
application interfaced through Excel tables) so that the installation
crew/ supervisors have the necessary information to locate any/all
cables/pipes etc. and the possibility to store the results of
controls/checks before giving the final OK for operation.

\(a\) Repair and Maintenance of FE Electronics

We maintain an electronics drawer at Chicago for testing and diagnosing
the various PCBs in the drawer. During this quarter the DAQ software for
this drawer was updated to make it's maintenance easier and functioning
more effective. A set of 45 repaired 3in1 cards was tested with the
revised system and shipped to CERN.

New low voltage power supplies, prepared by the Prague group, are being
installed in the calorimeter modules as part of the commissioning
process. During the commissioning campaign in December, front-end
electronics in 4 drawers was damaged by over-voltage from the supplies.
This will require substantial repair work in the months ahead.

\(b\) Commissioning and Integration work

In an earlier calendar quarter transition boards were built at Chicago
to connect the Tile Calorimeter trigger cables to the coincidence boards
for the cosmic ray trigger. Now the Level 1 receiver boards start to
become available and the trigger cables will be connected to them.

During the present quarter 8 additional transition boards were built at
Chicago to connect outputs from the receiver boards to the trigger
boards. This requires different connectors and different signal routing.
During the months ahead the full number of receiver boards should be
installed and the new transition boards will allow us to work directly
with their outputs and to leave the input trigger cables untouched.

Work was also done to upgrade the firmware in the trigger boards to
facilitate non-back-to-back triggers. This capability is needed to
provide a cosmic ray trigger useful for the endcap calorimeters.

A set of flow meters and a readout panel were prepared at Chicago and
sent to CERN for use with the cooling water for the drawer electronics.

A team of 5 Chicago people continue in full time residence at CERN
working on commissioning and integration. This team consists of one
postdoc, one graduate student, two BSc technical assistants, and one
full time electronics technician. They were supplemented by periodic
visits of faculty members and research personnel based in Chicago.

In November 2005 the barrel calorimeter was moved to its final location,
centered on the interaction point. Work is underway to connect
calorimeter modules to the off-detector services in USA15. This will
continue for many months. David Miller, a Chicago BSc technical
assistant is in charge of a team responsible for making the connections
to the calorimeter modules. As of late December 2005, the first full
sector of 8 modules had been connected to services on the C side.

It remains the case that electrical noise from the low voltage power
supplies is compromising the performance of the TileCal readout. Work is
in progress to understand and remove this noise but production is
continuing with the present performance. The supplies are needed for
commissioning the rest of the system.

\(c\) Calibration and Monitoring

Calibration and monitoring is an integral part of the commissioning
process. Martina Hurwitz, a Chicago graduate student, is co-leader of a
team responsible for processing and reviewing the calibration data taken
after a calorimeter module is connected to services in USA15. She has
set up monitoring histograms and reviewed all the calibration data
collected to date.

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

ITC pre-installation work is completed. Post-installation work will take
place in the next quarter. UTA graduate student, Hyeonjin Kim arrived at
CERN and is permanently based here. She will work on ITC related
pre-operations tasks. She is getting trained and learning TileCal
operations with the Barrel groups.

**3.4.2 Calibration & Monitoring**

**3.4.2.1 Pre-Operations** **Kaushik De (University of Texas at
Arlington)**

Some progress was made in planning ITC scintillator calibration. Armen
Vartapetian is looking at CTB data to understand performance. He is also
studying QC issues for TileCal. We are also getting involved in
commissioning database issues.

**3.5 Subsystem Manager\'s Summary**

**Frank Taylor (MIT)**

Installation and Phase II commissioning of chambers for the BW-Side C
and the EIL4 stations continued in B180 at CERN. At the end of December
05, the mechanical integration of four BW sectors was completed. In
addition, two EIL4 stations (EIL4A13 and EIL4C13) were completed and one
(EIL4A13) was installed in the ATLAS cavern.

The US group is organized with specific responsibilities assigned and is
working well together and with the CERN and Pakistani teams.

The Michigan group continued to lead the electrical testing of completed
sectors and stations (Phase II Commissioning). Three DAQ stations are
employed to commission the EIL4 stations, the chambers in the current BW
small and BW large sectors. Data collected are ported to the
commissioning database. The UoW team is responsible for the mechanical
integration of the EIL4 stations and the B-sensors for all the chambers.
The commissioning of alignment components is covered by the Brandeis and
CERN alignment group, who also oversee the photogrammetry of chambers
and sectors. All members (including Harvard and MIT) contribute to the
preparation of chambers for installation and their installation on the
support structures.

A very fruitful workshop on the calibration and monitoring of MDT EC
chambers was held in early November at the University of Michigan with
broad participation of the US ATLAS Muon Group. It was decided at the
workshop to have the UoM group organize the calibration and monitoring
of the detector during data taking. The BMC group and others will also
participate and various specifics of collaboration were discussed.

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

**Note #1**  Delayed. Two EIL4 stations (EIL4A13, EIL4C13) are now
installed in UX15, two are ready for installation (EIL4A05, EIL4C05) and
four are being prepared for installation

**Note #2**  The SW is significantly delayed - primarily due to the
delays of integrating the ECTs. The plan for the SW construction is to
start the tooling construction and commissioning in B191 after ECTA
exits for its 80-degree cold test in Jun-06. Following the completion of
ECTC in late summer 06 the SW team will start installation of chambers
in the first SW.

**Note #3**  The progress-to-date extrapolates to this completion date.
The top watched item is the completion of the delivery of the last small
wheel sector.

**Note #4**  Scheduled date is the best estimate at this time. However,
the TGC1 C-side wheel has to be installed first and many items of
tooling need to be designed, constructed and commissioned. Discussions
have started with the ATLAS commissioners and within the US community on
how to organize this task.

**Note #5**  A plan has been made and is being closely watched that has
the completion of Side A at the end of Sep-06. In order to succeed the
timely delivery of aluminum for the sectors is needed as well as
additional storage space in B180.

**Note #6**  Schedule believed to be possible, but means are being taken
to accelerate the completion date to 30-Sep-06 in order to clear space
for another TGC wheel assembly station.

**Edward Diehl (University of Michigan)**

Three DAQ stations are in use in B180 - one each for small sector, large
sectors, and EIL4. Electronics tests are done using standard scripts to
drive the DAQ. A operator\'s manual has been written. We also installed
PVSS software on all DAQ carts to permit readout of temperature sensors
and other DCS data (with the help of Joe Rothberg of Seattle). A 4th
station is being set up as a spare.

o UM personnel at CERN continued work on MDT sector construction and
testing along with personnel from other US ATLAS institutions. Resident
at CERN are Jay Chapman, Dan Levin, Claudio Ferretti, Manuela Cirilli,
and Andrew Eppig. In December, Tiesheng Dai joined them. Bing Zhou,
Curtis Weaverdyck, and Edward Diehl did some short trips to contribute
to sector commissioning. Jay Chapman and Teisheng Dai are focused on
electronics installation and testing, and Dan Levin is focused on gas
system installation and testing. Jay has coordinated the sector cable
fabrication, testing, labeling, and cataloging for the DB. The cables
required for each sector are 5 HV, 5 LV, 5 pairs of CANbus cables, and 5
optical fiber cables.

o Our group helped with the installation of the small sector test stand,
setting up the required supply of chamber gas, and electrical power. In
the Oct-Dec period 2 large sectors (C09, C03), and 2 small sectors (C04,
C02) were assembled and tested. They had to deal with a few problems
found on chambers, such as a some gas leaks and hot channels. In most
cases these were repaired, though a few hot channels had to be disabled
by cutting the HV connection to the tube.

o Completed sectors are tested in a variety of ways:

\- leak check

\- HV check

\- many tests of electronics functionality

\- long-term electronics burn-in test

\- spacer frame tension rods are adjusted as needed to remove chamber
bow

\- mechanical measurements (mainly done by other groups, but included
for completeness).

o Jay Chapman and Claudio Ferretti worked on the design and
implementation of the phase II database to store information on sector
parts and tests mentioned above. See Ferretti talk in
http://agenda.cern.ch/fullAgenda.php?ida=a057827 for more details on the
phase II DB.

o We began the process of moving our chamber and commissioning data to
CERN databases. There are 2 databases at CERN: MTF for part IDs of all
hardware which is sent to the pit and Oracle for all other chamber info.
Edward Diehl, Manuela Cirilli, and Claudio Ferretti are working various
aspects of this project. Edward Diehl has supplied all the chamber parts
IDs for the MTF database. Manuela is coordinating the transfer of other
chamber data to the CERN Oracle database as well as working on the COOL
database interface, by which the Athena analysis program interacts with
the Oracle DB. Claudio Ferretti is supplying the chamber commissioning
test data for the DB. This work will continue over a period of time as
more chambers complete the final commissioning process at CERN.

o Michigan hosted a very successful US Calibration workshop on Nov 4-5,
2005 with 50 participants from 11 ATLAS institutions. The agenda and
talks for this meeting can be seen at
http://agenda.cern.ch/fullAgenda.php?ida=a056852. The meeting covered
the full range of muon system calibration: CSCs, MDTS, alignment,
magnetic field, as well as calibration software and computing issues.

A consensus was reached at this meeting that Michigan should spearhead a
US MDT calibration center. This center would calibrate muon data on a
daily basis using a special calibration data stream from CERN. Michigan
would utilize both local computing resources, and also those at the
Tier-II center at Boston for this work. A follow-up meeting is planned
in 6 months.

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

The Pre-series system was used for commissioning of the pre-series
Region-of-Interest (RoI) Builder, of TDAQ software, and of the Tile
Calorimeter. Software commissioning included Monitoring, Event Filter
Dataflow, and High Level Trigger (HLT) algorithms. In addition to
support for TileCal commissioning, detector support activities included
Monitoring and support for new single-board computers. Software
maintenance involved improvements or updates to a number of software
components, including the Readout Subsystem (ROS), Configuration,
Monitoring services and HLT Steering. Operations activities included
operation of the Pre-series system, and system and network
administration.

**Bernard Pope (Michigan State University)**

Comune took part to the final review for the HLT Steering requirements
at the TDAQ week in Mainz. The review document has now been approved and
Comune has started looking into the implementation of those new
requirements in view of the milestones set by release 12.0.0 (DC3). In
particular, he has been developing new features in the PESA Core
Software to support physics analyses off AODs. These data for the first
time, thanks to these new features, will include trigger information and
will deliver the trigger decision to the physics analyses. Other
features pinpointed by the summer 2005 \"Steering Review\" include the
changes in the persistency mechanism in the Steering, needed for release
11.0.x (which is used as the validation release) and will go into
release 12.0.0 (due at the end of February 2006). This release is going
to be used for the DC3 production where the new features are needed to
perform combined Physics/Trigger studies.

At the same time Comune has kept providing support for the PESA software
commissioning at point 1. It is now possible to run Tile algorithms on a
subset of the real Tile detector installed in the ATLAS pit using the
PESA software coming with release 11.0.0.

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

Software Commissioning:

For commissioning and exploitation of the Pre-series system at Point 1
with HLT algorithms, a setup was run on the preseries machines using
eight ROS Emulators, one Level-2 Supervisor, and one Level-2 Processing
Unit. An installation based on offline release 10.0.6 was used together
with preloaded bytestream data containing Level-1 preselected single
muons, single electrons and jets. The algorithm setup contained electron
(T2Calo), muon (muFast), and inner detector (IdScan, TrigSiTrack, TRTxK)
selection algorithms which were run together in a common selection menu.
Instrumentation data were taken for different configurations to evaluate
framework overheads, network transfer times, and algorithm processing
times.

TDAQ Support:

Together with developers from the TileCal group a HLT Level-2 TileCal
selection algorithm (TrigTileMuId) was prepared for readout tests in
Point 1 (P1) in 2006. The setup is based on offline release 11 and was
tested on preloaded real data taken in an earlier TileCal commissioning
run.

**Robert Blair (ANL)**

Hardware Commissioning:

Jim Schlereth has been in consultation with G. Unel and P. Werner as
they begin to set up the RoIB system at Point 1. Some minor software
patches were needed to repair bugs that became evident and advice on
abnormal conditions was offered. Updated boards which fix some problems
that were encountered during testing at ANL have been shipped to CERN.
The old, unimproved, boards have been returned to ANL for updates.

Pre-Ops Software Commissioning

Unel and Stancu, with the Measurement Analysis Group, continued
investigating the performance of the Pre-series system and Dataflow
software, including studies of fault tolerance and the impact of
monitoring. Many other software components were also tested on the
Pre-series system. Kolos organized and coordinated tests for Monitoring
software. Results are being analyzed, including studying the impact of
Monitoring on the main data flow. Negri studied the Event Filter
Dataflow. Wheeler studied the efficiency of the protocols into and out
of the Event Filter for very small events (as will be present during
detector commissioning).

Pre-ops Detector Support

Kolos continued to lead the Monitoring group. He reported Online
Monitoring plans at numerous ATLAS meetings and reviews.

Unel connected the TileCal barrel section to the Pre-series TDAQ system.
Data was taken with sixteen Readout Links using the RoI Builder. The
TDAQ system was able to take data as fast as the TileCal RODs would
allow.

Unel adapted the diskless booting scheme to the newest single-board
computers used by the detector systems.

Pre-Ops TDAQ Support

Stancu fixed a bug in the implementation of the UDP message passing
software which prevented the development of the ROBIN network interface
based on UDP.

Wheeler configured the HLT software for use on the performance testbed
in Bldg. 32.

Pre-ops Operations

Unel coordinated operation of the Pre-series system. Stancu participated
in network operations of the Pre-series system.

Pre-ops Hardware Maintenance

Stancu worked on the frequency of internal updates of SNMP counters in
HP switches

**3.6.2 Operations**

**Bernard Pope (Michigan State University)**

New RoIB cards and a new version of the EPROMs were received from
Argonne and installed in the USA15 counting room. The old RoIB cards
were shipped back to ANL. A new 9U VME crate for the RoIB setup at
Argonne were received from WIENER and sent to ANL. The stand-alone tests
of the RoIB and L2SV were run both from ANL and from CERN. Ermoline has
obtained an account on the Point 1 computers and is setting up an
environment in order to test the RoIB. The RoIB is equipped with a
second output HOLA card on the RoIB Builder card and the second L2
Supervisor with one more FILAR input card. This gives the possibility of
running the ROIB with two L2 Supervisors. Ermoline participated in the
RoIB FDR/PRR (Final Design Review / Product Readiness Review). The RoIB
has been prepared for integration with MUCTPI of the L1 trigger. The
ODIN LDC card was installed on the RoIB Input card and connected to the
output of the MUCTPI. Ermoline reported on the status of rack DCS during
the DAQ/HLT-I Coordination meeting. The rack DCS installation in SDX1 is
now planned for January 2006, when the CANbus power crate will be
delivered.

Kolos developed a new implementation of the Error Reporting Software
(ERS) component, incorporating more information on errors. He
incorporated advanced facilities for information definition in the
Information Services (IS) component and updated the IS documentation. He
also improved the performance of the Histogramming components.

Unel began adapting both Readout Subsystem and Configuration software,
for both 32-bit and 64-bit CPUs, to a new C/C++ compiler. He modified
the database generation scripts and added functionality for TDAQ
operations with multiple concurrent partitions.

**David Lissauer (Brookhaven National Laboratory)**

**End-cap Toroid:** The problem with the helium cooling tubes which had
been discovered in November 2005 was investigated. Unfortunately the
situation with the cooling tubes was serious and they will have to be
replaced. The cooling tubes are square on the outside and a small
diameter cavity on the inside. They were made of 6 meter long sections
and that were joined together to make the full length of pipes that are
up to 40 meter long. The pipes were tested and were found to be good
after they were joined together. At that point they were welded onto the
EC Toroid heat shield. At that stage is seems that too much heat was
applied and the tubes were damaged. Lots of small cracks appeared and
the tubes cannot hold the pressure. The operation will start in January
2006 and the estimated delay is in the order of two months.

**End-cap Calorimeter Installation:** The EC calorimeter has been placed
on the 22 EC tile modules. The placement in X,Y seem to have gone well.
The Z position of the LAr relative to the tile had to be shifted by 9 mm
(LAr further out in Z). The move is due to the fact that the LAr support
that is attached to the tile could not be positioned well enough.
Meetings took place with Technical Coordination (TC) engineers to
understand the implications to the placement of other detectors. There
are a few options that we are investigating. We can try to move the Tile
in putting the LAr in nominal position or place the Tile in nominal
position and the LAr will then be out in Z. The final solution will
probably be somewhere between these two extreme options. Discussions
took place to decide how we would like to install the EC-A. i.e. should
we try to reproduce the same misalignment as on side C so that the
experiment will be as symmetric as possible.

**Muon Chamber Installation:** The BMS (Barrel Middle Small) chambers in
six sectors have been installed and we still have to install the
chambers in Sectors 4 and 6. In the mean time preparation for the
installation of the barrel chambers has gone in to high gear with the
arrival at the hall of the movable platform that will be used for the
chamber installation. The movable platform will be assembled next week
and the plan is to start the installation of the BOS (Barrel Outer
Small) chambers before the end of 2005. The installation of the chambers
will start at an increased rate early 2006.

The muon installation platform (20 meter long, 3 meter wide) made by
ALIMAK was installed in the hall. Meetings with the CERN safety group
took place to discuss the operation mode of the platform and to obtain a
European Certificate of Compliance.

**Barrel Toroid Magnet*:*** During the fall of 2005 the magnet team
reported on the results of the release of the jacks that supported the
Barrel Toroid warm structure of the barrel Toroid magnet. The
expectation from the finite element calculation is that the structure
will sag by 22mm. The engineers recommended that we assemble the
structure assuming 30 mm sag to take in to account a few additional mm
expected due to expected imperfection in the shims. The measured sag due
to the barrel Toroid weight alone was 18mm. We expect an additional 8-9
mm sag due to the weight of the muon chambers and services. We could see
additional few mm sag due to creep. So all in all this is a great
achievement by the magnet team.

In late 2005 the committee was able to report that the work on
connecting the Cryo-ring and on the last sector connection was moving
forward. The bus bar delivery is now on the critical path for performing
the first magnet test.

**Barrel Calorimeter Services:** Connections to the Barrel Calorimeter
of the water supply and cables has started. The Inner Detector pipes are
nearly done on the surface of the calorimeter. Liquid Argon and Tile
trigger cables are being connected all the way to the counting room. The
rate is still low -- but the plan is well defined now and at this stage
is not in the critical path. One worrying aspect that the LAr
calorimeter that was supposed to be isolated from the tile and the ID
seems to have a short at some point. A small team of experts is looking
for the reason the grounding rule has been violated -- but up to now the
reason has not been found.

**Rail and Barrel Calorimeter Positioning:** I gave a report to the TMB
on the excellent results of the placement of the Barrel Calorimeter at
Z=0. The survey team gave a report on their work during the move and the
nice results obtained by the Hydrostatic system -- it measured the floor
movement of fraction of a millimeter during the move and slow sinking of
the floor the following days at the rate at the level of microns. We
signed off on the calorimeter position and connections of the LAr
services which have started. The solenoid magnet chimney is in position
and the team from Japan (KEK/Toshiba) will come to make the connections
between the solenoid/chimney and control dewar.

**LHC Schedule:** Miikka Kotamaki presented an up-dated schedule. The
installation task force worked out this schedule in the last few months.
The schedule is aggressive especially regarding services installation.
From our experience to date it is clear that the largest uncertainty has
to do with the time needed to install the large amount of cooling pipes,
cables etc. The large objects installation has gone quite well so far
and the time estimate and resources needed has been quite accurate. On
the other hand, the time and resources needed to install the services
and electronics in the pit has been vastly underestimated.

**Access:** A. Gordeev from BNL was at CERN and a meeting took place
with Michal Raymond to discuss the status of the access and installation
tooling that he is designing at BNL. Michal Raymond is taking over from
Tommi Nyman who has left for a new position in Finland -- this has
resulted in BNL having to take more responsibility than before for the
assembly and operation of the equipment. We will have a similar problem
with the movement control that we are doing in the US (ANL) and, I
expect that here too we will have to fill in at least temporarily some
of the functions that were covered by Tommi.

**ATLAS Upgrade:** Discussions took place with engineers from ALICE
experiment to understand some options for Carbon fiber structures that
we can use for the ATLAS upgrade. We expect that A. Gordeev will follow
up on this and conceptual design for the ATLAS upgrade will be
developed.

With Marzio Nessi we started to develop the charge for the ATLAS Upgrade
Project Office that will be charged with coordinating the execution of
the ATLAS upgrade. The main idea is that in the first phases of the
upgrade activities will include the conceptual design, prototype and
even construction work. The Project Office function will be distributed
among a few large Labs -- CERN, Rutherford, Nikhef and possibly BNL.
While in the R&D stage the engineering will be at the outside Labs, and
then during the installation stage most of the functions will be
concentrated at CERN. The aim will be to have a document ready for
discussions in early 2006.

**Safety Issues:** The unfortunate accident that happened in the LHC
tunnel has had an impact on the work in the cavern. The enforcement of
safety rules has intensified and all people involved in the installation
are much more aware of the need to follow safety rules. This has slowed
down the work on the access significantly as new reviews of the planned
scaffolding took place and the requirements for example of safety rails
have been intensified. All people working on the scaffolding have gone
through special training for working at heights.

**Magnetic Field Workshop:** A two-day workshop on the magnetic field in
ATLAS took place. There is now a large effort to prepare for the
magnetic field mapping of both the solenoid and the Toroid fields. We
expect the solenoid and the Toroid tests to take place in the spring of
'06. Iuliu Stumer gave the results of his calculations for the Toroid
field. The calculations now include a lot of the magnetic material that
surround the Toroid.

**Positioning Strategy:** I gave a presentation on the placement
strategy and the plans for the placement of the next objects. We have
now gotten agreement on the placement "drivers" for each of the blocks
being installed. For example the barrel system that is assembled on the
truck and consists of: Barrel Tile Hadronic calorimeter, Barrel Liquid
Argon electromagnetic calorimeter, Solenoid magnet and warm Inner vessel
(used later on the ID installation). When we move to the final position
all the above items would like to be aligned to the beam pipe but
clearly we can align the whole system as one object. Thus, it was
decided after discussions and optimization that included physics,
effects on magnetic field, etc. to align the system using the barrel
solenoid. Similar decisions have been taken and agreed for the EC
system, EC Toroid and Muon system. Discussions with the software people
have started to decide how best to translate the "as built" model being
established by technical coordination in the model that exists in the
simulation packages. (Geant 4)

**[4.1 Inner Detector Upgrade R&D]{.underline}**

**Abraham Seiden (UCSC)**

Work on the inner detector R&D is continuing in all areas. Some
highlights:

Several sensor types are in fab: #D pixels, stripixel detector. n-on-p
detector layout is continuing.

The 6 module stave is nearly complete. This includes new hybrids, a new
bus cable, and 4 of the 6 detectors bonded. The performance is good.

A 0.13 micron pixel chip has been irradiated to 70 Mrad. No problems
observed to date, will continue with irradiation.

Three generations of SiGe from IBM (5HP, 7HP, 8HP) are in Ljubljana for
neutron irradiation. These are expected back in April. A SiGe front end
has also been submitted this month for fab.

Test setups and procedures are coming together for a number of data
transmission tests among a number of groups (Oklahoma State, SMU, Ohio
State).

**4.1.1 Detectors**

**Hartmut Sadrozinski (UCSC)**

4.1.1 Detectors

Fabrication of a group of wafers, mostly with full 3D, active edge
sensors to match the ATLAS front end pixel readout chip was started. The
run was carried past step 28 (of 107), mask step 2 (of 7) and page 26
(of

67\) on the run sheets. This includes the growth of the field oxide,
bonding to the backside support wafer, and the etching of the first set
of electrode (N) holes, one of the slower steps, as the wafers must be
etched one at a time.

Sensors with three n and three p electrodes in each ATLAS pixel, from an
earlier run were irradiated in a reactor at Praha up to a fluence of 8.6
x 10e15 1 MeV neutrons / cm\^2

UNM activities covered characterization of leakage current, depletion
voltage, electrode capacitance, and charge collection speed on samples
of 3D sensors of a pre-ATLAS design, both non-irradiated and irradiated
to a fluence of 1015 55MeV protons. Two- and three-dimensional
electrostatic calculations based on the geometry of the sensor
electrodes were performed.

The work covers measurements of electrical parameters (interstrip
isolation and capacitance) and breakdown behavior on novel p-type
detectors, as built and after moderate gamma irradiation. The aim is to
evaluate the differences between Float Zone (FZ) and Magnetic
Czochralski bulk materials.

The test set-up for the ATLAS SCT is being modified for charge
collection efficiency measurements using a source.

Work continues on the design and layout of new 3 cm long detectors to be
manufactured on 6\" wafers by a commercial manufacturer.

Work continues on the Short Strip/Stripixel Detector characterization
station. Characterization of both n- and p-type stripixel detectors
continues.

Design for a small 3 cm x 3 cm test stripixel detector submitted to RD50
for fabrication. This design features of variety of pixel designs that
will permit an evaluation of how layout, pitch, and gaps will influence
S/N.

Quotes for fabrication of short strip for stave development are sought
from SINTEF and Hamamatsu.

**4.1.1.1 Innermost Pixel Layer**

**Alex Grillo (UCSC)**

University of New Mexico Activities reported for S. Seidel

UNM activities during the October to December 2005 period concerned
characterisation of Leakage Current, Depletion Voltage, Electrode
Capacitance, and Charge Collection speed on non-irradiated and
irradiated samples 3D sensors of a pre-ATLAS design. The preliminary
results were presented at the Inner Detector Upgrade Workshop at UCSC on
November 10. The measurement of reverse bias leakage current on the
non-irradiated n electrode confirms that the n electrodes are not fully
isolated from each other due to the oxide surface charge. After
irradiation to a fluence of 10\^15 55MeVp the n electrodes are isolated
and the leakage current for a single isolated n electrode is 400 nA
(Tnorm = 20C) at 60 Vbias. The p electrode shows a leakage of 300 nA
(Tnorm = 20C) at 60 Vbias. Depletion voltage was obtained from an
LCR-meter based CV measurement and by reading out the signal response to
a pulsed laser. The preliminary results were Vd = 10V for the
non-irradiated sensor and Vd = 80V for the irradiated (10\^15/cm2
55MeVp) sensor. These depletion voltage measurements were performed on
the single isolated n and p electrodes. Electrode capacitance was
measured directly using an LCR meter and indirectly by extracting it
from the decay time measured with a Picoprobe and a pulsed laser. The
results of the direct measurement are 68 fF for the non-irradiated
nelectrode, 120 fF for the irradiated (10\^15 /cm\^2 55MeVp) n
electrode, 32 fF for the non-irradiated p electrode, and 59 fF for the
irradiated (10\^15 /cm\^2 55MeVp) p electrode. The results of the
indirect method of measuring capacitance are 71 fF for the
non-irradiated p electrode and 80 fF for the irradiated p electrode.
Two- and three-dimensional electrostatic calculations based on the
geometry of the sensor electrodes were performed and resulted in an
electrode capacitance of 31 fF. The speed of the charge collection in
the 3D sensor was measured by illuminating the area near the isolated p
electrode with an IR laser pulsed as fast as possible and observing the
rise time of the sensor response. With a pulsed laser duration of
approximately 0.3 nS the p electrode output rise time was measured to be
about 2 nS for both the non-irradiated and irradiated samples.

**Sherwood Parker (University of Hawaii)**

1\. Fabrication of a group of wafers, mostly with full 3D, active edge
sensors to match the ATLAS front end pixel readout chip was started. The
run was carried past step 28 (of 107), mask step 2 (of 7) and page 26
(of 67) on the run sheets. This includes the growth of the field oxide,
bonding to the backside support wafer, and the etching of the first set
of electrode (N) holes, one of the slower steps, as the wafers must be
etched one at a time.

2\. Sensors with three n and three p electrodes in each ATLAS pixel,
from an earlier run were irradiated in a reactor at Praha. The most
heavily irradiated was exposed to 8.6 x 10e15 1 MeV equivalent neutrons
per sq. cm., about triple the amount requested for the ATLAS B layer
replacement and LHC upgrade. This work was done by Cinzia Da Via of
Brunel U. and members of the S. Pospisil group at the Czech Technical
University.

Note 1: A report for the next 3 months would show the fabrication run,
is now at step 83, mask step 4, and page 51. At this point, just prior
to metal deposition (with metal, overglass and dicing mask steps
remaining), Chris diverted to depositing and etching a temporary metal
pattern, covering enough pixels per probe point to allow a manual test
for a preliminary value of the yield. One wafer, which could produce
enough devices for all the solder bump bonds the group would need and
could afford, had a preliminary yield of 80% (24 good, so far, of 30
measured).

Two other wafers had the metal to electrode contact problems seen
earlier.

Spotting that at this early stage is now permitting tests that are
starting to indicate the causes. These tests have also shown, during the
last few days, that large edge leakage currents seen with the temporary
metal, and never seen before, are removed by a normal later step, the
forming gas anneal (step 89, page 55).

Note 2: A report for the next 3 months would show that charge signals
(from an infrared laser microbeam) can be seen in the most heavily
irradiated ATLAS-pitch test sensor from the earlier fabrication run.

Short Strip/Stripixel Detector Characterization Station

Detector motherboards, leakage current measurements boards, and
capacitance measurement boards have been fabricated. Readout boards with
low noise Viking chips have their preliminary layout completed (by
Milano collaborators), with final layout to be completed within next few
weeks. Fabrication to be done in Italy, assembly at BNL. Duplicate test
stations exist at both BNL and Milano.

Stripixel Detectors

N and P type prototype stripixel detectors fabricated since a year.
First N-type stripixel detector mounted on detector motherboard.
Preliminary capacitance and leakage current measurements done at BNL.
Detector has been taken to Milano for further testing. Initial results
indicate abnormally low interstrip resistance. Awaiting fabrication of
more motherboards to mount more detectors and test both at BNL and
Milano.

Meanwhile, have begun manual probing of remaining N and P-type detectors
to test a subset of strips to pre-select detectors prior to mounting on
motherboards. Probing done at BNL by New York University personnel.

Measurements on subset of wirebonded stripixel detectors (one n-type,
one p-type) also being done at UC Santa Cruz. Measurements are
preliminary but will be reported soon.

RD50 Test Stripixel-like detector

Design for a small 3 cm x 3 cm test stripixel detector submitted to RD50
for fabrication. This design features of variety of pixel designs that
will permit an evaluation of how layout, pitch, and gaps will influence
S/N.

Short Strips for Stave development

Currently have quote from Sintef for fabrication of batch of short strip
detectors. Am currently pursuing quote from Hamamatsu for comparison
purposes. Need to agree on dimensions of detector.

**4.1.2 Front-End Electronics**

**Alex Grillo (UCSC)**

A pixel test chip in 0.13 micron technology has been irradiated at the
88" cyclotron to 70 Mrad with no observed degradation. More irradiations
and SEU studies will follow.

Test structures of 3 SiGe technologies have been pre-radiation tested
and sent to Ljubljana for neutron irradiation. The basic design of a
SiGe demonstration chip is complete. Final layout details and
cross-checks are in progress and on track for an April submission for
fabrication.

**4.1.2.1 Deep Sub Micron for Pixels**

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

0.13um prototype test chip previously fabricated has been irradiated to
70MRad in 88\" cyclotron. No degradation observed. More irradiations and
SEU studies to follow.

**4.1.2.2 SiGe for Strips**

**Alex Grillo (UCSC)**

We have obtained test structure arrays from our collaborator at Georgia
Tech for three generations of IBM SiGe technologies, 5HP, 7HP and 8HP.
Testing of the first batch of these samples was completed and the parts
were sent to Ljubljana for neutron irradiation, which will be performed
in early January just after the holiday break. We anticipate having
these parts returned to us in March or April after their activation has
dropped to acceptable levels.

Work has started to automate the electrical testing. A "connector card"
has been built which interfaces a standard SCSI cable to the small
connector on the test card containing the test structure array. This
SCSI cable then attaches to a switching matrix which can be controlled
by a computer which also controls the parameter analyzer. In this way, a
computer program can control the sequential measurements of all devices
on one array in an automated fashion eliminating the need for probing
the separate leads of each device. This should greatly reduce the time
required for electrical testing.

Two more batches of test structure arrays have been received from
Georgia Tech. These will be tested as soon as the automated test system
is ready and then irradiated with gammas at BNL and protons at CERN this
spring and summer.

The design of a demonstration IC using the IHP SG25H1 SiGe technology is
progressing well. This technology is being radiation tested by our
collaborators in Barcelona. We chose it for our demonstration IC because
the cost of fabrication will be considerably less than for a comparable
IBM process through MOSIS. We were unable to make the Jan-06 submission
date because of M&O duties at CERN for the engineering staff but are on
track for the mid-Apr-06 submission. The basic design is complete.
Details of the layout and design rule checking are being worked out.

**4.1.3 Optical Readout**

**4.1.3.1 Diode Receivers**

**Flera Rizatdinova (Oklahoma State)**

The initial test setup (arrived from Ohio State U.) for measurements of
the PiN diode arrays characteristics is in place. The training has been
done using this setup. An additional equipment necessary for further
tests is ordered.

Potential vendors of the PiN diode arrays are identified and currently
we are in contact with these vendors

**4.1.3.2 Fiber Drivers**

**Jingbo Ye (Southern Methodist University)**

Test procedure and system level architecture for in-lab and in-radiation
tests of the GOL chip have been defined. Schematics of testing circuits
are designed and reviewed with people from Oxford UK and from the Micro
Electronics Group at CERN. Test equipment has been identified.

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

One of the goals of the R&D program is to identify the PIN and VCSEL
arrays that can survive in the intense SLHC radiation environment. We
have performed a survey of the commercially available arrays and
identified several potential candidate arrays. The next step is to
purchase the arrays and package them so that they can be characterized.

**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: the micro twisted pair cables and
fiber ribbons. The former transmits the LVDS signal between the optical
components and the pixel modules. The latter transmits the optical
signal between the optical components and the counting room. The ribbons
consist of several meters of radiation-hard, low bandwidth SIMM fibers
spliced to \~100 m of radiation tolerant, medium bandwidth GRIN fibers.
At SLHC, we expect to transmit data at \~Gb/s.

We have constructed a prototype test system to measure the bandwidths.
From the measurement of the rise and fall times and the "eye" diagrams,
the preliminary conclusion is that the micro twisted pairs can transmit
signals at up to 640 Mb/s and the fibers at up to 1 Gb/s. The current
infrastructure therefore satisfies the needs of the SLHC. More detailed
study is in progress.

**4.1.4 Modules**

**4.1.4.1 Stave Structures**

**Carl Haber (Lawrence Berkeley Laboratory)**

The effort here focuses on building and testing a 6 module stave. Each
module consists of a single CDF Run2b surplus detector and a new ATLAS
ABCD hybrid (see 4.1.4.1) developed for this project. To date we are
part-way though fabricating and testing the first of these 6 module
staves. We developed and fabricated a new bus cable and laminated 2 of
these to carbon/foam/PEEK stave cores and cooling channels. We then
mounted 6 hybrids (with no detectors) to this structure. It was fully
bonded and tested with the existing ATLAS DAQ. A hybrids were seen to
read out properly. We then started mounting and bonding hybrids to
detectors. To date four have been mounted and 3 of these have been
tested as individual units. They were seen to perform as expected for
ATLAS electronics. Two of these have since been mounted and bonded to
the stave itself. Their performance on the stave is as expected as well.
We will continue to mount the remaining 4 to complete the stave.

A new DAQ system is under development to allow us to control and read
large number of stave based modules in parallel. This system is based
upon the National Instruments High Speed Digital I/O series of LVDS
cards. These cards in in hand and code is being written to control them.

A new 3cm detector design is underway at BNL. Quotes have been solicited
from 2 vendors.

**4.1.4.2 Hybrids**

**Carl Haber (Lawrence Berkeley Laboratory)**

The ATLAS hybrid for the stave was designed and fabricated last year. It
performs as expected. About 60 were manufactured. About 20 of these have
been built so far and performance is as expected. Four hybrids have been
integrated with detectors, three of these have been tested and perform
well.

**4.1.4.3 Cooling Channels**

**Carl Haber (Lawrence Berkeley Laboratory)**

Working in consultation with W.Miller studies of stave geometry and
materials in terms of a 1 and 2 meter stave are underway. Thermal
gradients and deformations, and gravitational sag have been studied.
Iterations are underway particularly aimed at controlling
gravitationalsag.

**4.1.4.4 Powering Schemes**

**Carl Haber (Lawrence Berkeley Laboratory)**

Design work continues at LBL on a DC-DC conversion scheme. The group at
RAL is designing an interface card for serial powering which can go on
our 6 module stave. We are redesigning the stave bus cable to connect to
this card. A second 6 module stave with serial powering will be built
using the RAL card, our hybrid, and this new bus cable. We aim to test
all this in June 2006.

[**4.3 Liquid Argon Upgrade R&D**]{.underline}

**Francesco Lanni (Brookhaven National Laboratory)**

The R&D activities for Liquid Argon in most of the WBS level 4 nodes
have not been started yet pending also the availability of some of the
funds. Some study has begun at SMU for the optical data link: radiation
studies have been carried over for a laser driver chip on 0.5um SoS
technology as well as the design of a test chip submitted in October at
Peregrine and the test setup for measurements in-lab and for
irradiation. Also some design studies of test structures for the PLL
block has begun (always at SMU).

**4.3.2.4 Optical Data Link**

**Francesco Lanni (Brookhaven National Laboratory)**

The laser driver chip of 0.5 um SoS technology has been irradiated at
MGH with 200 MeV proton up to 100 Mrad. Data analysis has been carried
out and identified current leakage in SoS CMOS design. Solutions have
been researched and proposed. A dedicated SoS technology test chip was
then designed and fabricated with support from Peregrine. This chip was
submitted in Oct. 2005. The in-lab and in-radiation test setup has been
designed at system or architecture level. Schematics work has been
started. Test equipment is been identified.

On the Link-on-Chip (LoC) front, preliminary studies have been carried
out on the PLL block, the most critical part in the LoC design. A
preliminary VCO and PLL together with PFD, dividers have been put on the
SoS test chip.
