**December 2003**

############################### Project Description

The Tevatron Collider at Fermilab offers a unique capability to
elucidate many of the major issues currently facing particle physics.
Its high center-of-mass energy and recently upgraded luminosity offer us
the capability of shedding light on the Higgs mechanism - which has the
potential of offering insight into the origin of mass - and pushing the
boundaries of searches for supersymmetry and other new phenomena beyond
the Standard Model. It also makes accessible improved precision
measurements of the W boson and top quark properties that, by further
constraining the Standard Model, provide increasingly stringent tests of
its precepts. The Tevatron offers the most cogent experimental probes of
Standard Model physics, and beyond, during the coming 5+ years.

The Run IIb D-Zero Detector Project has been designed to allow the
D-Zero Experiment to continue operating in the high intensity Tevatron
environment for the remainder of the coming decade. The integrated
exposure of the D-Zero Detector to colliding beam will result in
radiation damage to the silicon detector that will compromise its
efficiency. Adequate b-tagging is an essential ingredient of the Run II
physics program. In order to maintain adequate b-tagging, D-Zero is
adding an inner layer detector of radiation-hard silicon to enhance
tracking efficiency as the Run IIa detector ages. In addition, the
trigger system must be upgraded in order to provide sufficient rejection
and to limit the dead time at the higher instantaneous rates that will
be delivered by the Tevatron as the run progresses. The Run IIb D-Zero
Detector Project provides for the additional D-Zero Layer 0 silicon
detector and the upgrade of the D-Zero trigger, DAQ, and online systems
in order to enable the continued efficient running of the experiment,
and the acquisition of forefront physics data, for the foreseeable
lifetime of the Tevatron collider program.

############################### Overview of Project Status 

The project continues to show good progress. The newly baselined silicon
Layer 0 project met its milestone of freezing mechanical parameters 3
weeks ahead of schedule and continues to make impressive progress. Work
is happening to pull together the production readiness reviews needed to
start producing the parts for the L0 detector (see procurement
highlights).

The L1 Cal trigger has successfully integrated most of its components
and work is going on to finalize the ADF design before moving the next
prototype and production to MSU.

UIC has started its design of the SCLD card for sending out the Serial
Command Link signals to the ADF. Meanwhile the GAB board has gone out to
the fabricator. The firmware and software for the Cal Trk-Match has been
aggressively pursued, with the firmware completed, though not yet
tested, and the software far along. With the rebaselining, work has
restarted on the STT trigger. A new round of simulations of the full
trigger system is underway. The CTT (DFEA) boards are back from vendor
and tests are beginning.

Correcting an error in schedule updating for November results in an
apparent gain of 41 days in the L1 Calorimeter trigger effort. This gain
is due to a schedule update error. This milestone was erroneously
reported to have slipped by 41 days during November when in fact its
forecast date has not slipped.

############################### Project Milestone Summary (as of 31 December 2003)

The DOE baseline milestones are shown in Figure 1 as solid diamonds.
These fixed milestones are defined in the modified DOE Project Execution
Plan approved in December 2003. Shown as open diamonds on the same line
are the project's projected dates for achieving the milestones. Actual
dates of achieving milestones are shown as solid stars. The silicon,
trigger and online milestones are shown separately with milestones
sorted by current forecast date. Note that the projected L1 Cal-Track
milestone date for production and testing is beyond the DOE baseline
milestone. This is due to a change in how the calorimeter track-match
trigger will be tested -- the early prototype is identical to the
current muon L1 trigger board, and the L1 cal and CTT prototypes are
being tested with the muon trigger board to assure compatibility. The
Cal-Track match is not a critical path item. We plan to review the dates
for this plan and make a change request for next month to move the
official milestone date in sync with this plan.

Table 1 shows the difference in the current forecast and last month's
forecast for achieving the DOE milestones. This table lists all the
approved Level 0-1-2 DOE milestone dates along with the project's
current (and previous month's) forecast for achieving them. The list is
sorted by DOE Milestone date. Milestones with forecast dates that have
changed significantly in the last month are discussed in Section IX of
this report.

############################### Management Highlights -- J. Kotcher

The project was successfully rebaselined in December. The descoped
silicon project (L0) was projectized and successfully put through COBRA.
Work is ongoing to understand the COBRA output and validate it.

A new management structure was put into place for the L0 project. Some
changes to the trigger structure and management was made to reflect new
responsibilities, most notable a new subtask 1.2.8 was added for
managing the possible AFE replacement. At the moment this effort is
purely R&D and not supported by project funding. While we are closely
following the R&D work, it is beyond the scope of this report. Once a
decision has been made on this effort, it will be baselined and included
in the monthly reports.

# Procurement Highlights 

No procurements of substance were planned or made in December. The
silicon L0 project is planning procurements for March for the sensors,
hybrids and analog cables. This represents about \$161k for the sensors,
\$35k for the hybrids and \$103k in analog cables or nearly \$300k in
total. Work is starting to organize the Production Readiness Reviews for
this round of procurements.

############  {#section .unnumbered}

I.  **Silicon L0 (WBS 1.6) Schedule and Budget Information -- A.
    Bean, R. Lipton**

There was substantial progress in December. The project was formally
included in the rebaselined D0 upgrade. A grounding and isolation
workshop was held on December 3^rd^ and a decision was made to isolate
the detector at the adapter card ring. The Dec 16 milestone for the
freezing of mechanical parameters was met. With these parameters frozen
final design and drawing work is proceeding on the long lead-time items
(sensors, analog cables, and hybrids). The Run2b layer 0 closeout
structure was delivered to Fermilab, detector modules mounted, and noise
was measured to be well within acceptable limits.

############################### Sensors (WBS 1.6.1) -- M. Demarteau, R. McCarthy

> The Technical Design Report for the Layer 0 detector calls for four
> sensor types: sensors with strip pitch of 71 mm and 81 mm, with a
> length of 70 and 120 mm. We have decided to buy for the Layer 0
> Detector 25 sensors of each type (25 sensors, 70 mm long with a pitch
> of 0.071 mm, 25 sensors, 70 mm long with a pitch of 0.081 mm, 25
> sensors, 120 mm long with a pitch of 0.071 mm, 25 sensors, 120 mm long
> with a pitch of 0.081 mm). We have received a quote from Hamamatsu of
> \$88,000 for these sensors. The quote would not be significantly
> reduced if we purchased only one type of sensor, so we are able to
> maximize the efficiency of the detector. Discussion of the sensor
> specifications has been is progressing within the group.

############################### Readout (WBS 1.6.2) -- A. Nomerotski, R. Sidwell

> Several L0 hybrids of the latest revision from Amitron have been
> assembled and successfully tested, minor layout modifications have
> been identified (mostly in the solder mask layer to increase the
> solder pad dimensions). The new, lower profile MOLEX connectors for
> the hybrids and digital jumper cables have been tested. Two L0 modules
> with earlier revision L0 hybrids have been installed at the new L0
> support structure and successfully tested. The noise level has been
> measured at the acceptable level without any additional shielding of
> the structure with the modules. A preliminary approach to the
> electrical isolation of the L0 detector has been chosen at the
> mini-workshop in the beginning of December after comparison of
> performance for several schemes. The isolation will be implemented at
> the Adapter Card by appropriately using transition from the
> single-ended to differential modes and back (for single-ended
> signals). The new revision of the Adapter Card will be required. Two
> long lead time items, twisted pair cable and MOLEX connectors, have
> been ordered. A mixed SVX2/SVX4 system was successfully read out at
> the 10% test stand.

############################### Mechanical Design and Assembly (WBS 1.6.3) -- W. Cooper

> The radial and azimuthal arrangements of sensors for L0 were developed
> and design parameters were frozen. Preliminary sensor drawings showing
> sensor features compatible with the design were made and distributed
> for comment. Designs were developed for pitch adapters to connect
> between analogue cables and sensors. Procedures for installation at D0
> were re-examined and incorporated as input to the design.
>
> The University of Washington completed and delivered a L0 support
> structure for use in electrical prototyping; the structure geometry
> was based upon earlier Run 2b parameters. Methods to provide
> north-south electrical isolation in the support structures were
> considered, but based upon electrical testing we conceded that
> isolation should not be needed. An initial finite element analysis of
> deflection of the new L0 support structure under its own weight was
> completed.

############################### Detector Modules and Integration (WBS 1.6.4, 1.6.5) -- L. Bagby, J. Fast

> As part of the closeout we assembled two L0 modules on the prototype
> L0 structure from the University of Washington. These modules are
> being studied to confirm that the grounding strategy developed for the
> full Run IIb upgrade is sound and can thus be applied to the
> re-baselined project L0 device. Additional L0 modules are being
> produced using the latest hybrid prototypes, which feature a revised
> ground plane layout and ground points for direct connections to the
> structure. These will be installed on the prototype structure in
> January to complete the grounding and noise studies for the closeout
> and to resolve any outstanding issues for the new L0 detector.

############################### Trigger (WBS 1.2) Schedule and Budget Information -- B. P. Padley, D. Wood

December had a significantly fewer working days compared to other
months, due to the holidays. Nonetheless, significant progress was made
in particular areas as detailed below.

In the project office, work was done in December to update the project
schedule to reflect the changes in tasks and dates that result from the
shift of responsiblities from the Saclay group. Thus, some tasks have
been closed out and others added.

1.  **Level 1 Calorimeter Upgrade (WBS 1.2.1) -- M. Abolins, H. Evans**

> During the month of December testing of the ADF prototype continued at
> Saclay. Serial communication between the ADF and SCLD was completely
> verified and digital filter/peak detector outputs were compared
> between hardware and test software with various pre-loaded input
> signals. The Channel Link outputs of the ADF were also tested and
> debugged using a custom made Channel Link receiver mezzanine card. The
> tester can generate a pseudo-random pattern identical to that
> generated by the ADF, so that all data bits can be checked. All 3
> output links were tested with raw and filtered ADC data, with
> pseudo-random pattern and constant data patterns. No data error or
> parity error were detected on any link in any mode over the \~20 min
> of each test.
>
> The big news, however, was that problems with clock multiplication in
> the ADF Xilinx chips were resolved. The turned out to be due to
> incorrectly driving clock signals on the ADF backplane and will not
> require any hardware modifications to resolve as had been feared in
> previous months.
>
> The ADF prototype board, SCLD mezzanine board and Virtex II evaluation
> kit were shipped to MSU at the end of December. Work on the analog
> section of the ADF will be continue using the single channel ADF
> mezzanine card at Saclay while integration of the ADF prototype and
> reduced SCLD occur at Fermilab.
>
> Work also continued on the Serial Command Link Distributor (SCLD) at
> UIC. The group there has reviewed the Saclay documentation on the
> board and a first meeting with Saclay was held to discuss the design.
>
> The GAB prototype was sent to the fabricator at the end of November.
> During December we waited while paperwork for this order cleared the
> Columbia purchasing department. A purchase order should be available
> in early January, after which fabrication will take approximately one
> week.
>
> While waiting for the GAB to arrive, work continued on the TAB and GAB
> test systems. TAB firmware was updated to allow for more flexibility
> in the next round of integration tests. The main functionality of the
> GAB test software was also completed during December. Everything is
> therefore in place to test the GAB prototype as soon as it arrives
> from assembly.
>
> The process of porting online software from Windows to Linux
> environments continued during December at MSU. The next step will be
> to integrate the existing ADF and TAB/GAB test software into this
> online environment. Discussion of this has already started and the
> work should begin in January.
>
> On the simulation front, new plans have been drawn up for the next
> round of simulation using the new trigger system. The preliminary goal
> is to have new simulation results in a variety of physics channels
> using code that combines all of the upgraded trigger simulations by
> early summer. Milestones on the way to this goal and beyond are under
> discussion.

2.  **Level 1 Calorimeter/Track Matching (WBS 1.2.2) -- K. Johns**

> Final review of the MTCxx card design was worked on lightly. Design
> changes to the MTCM were completed and awaiting a final review. FPGA
> code for testing the serial link transmitters and receivers on the UFB
> was completed but tests were not yet run. Work also continued on the
> L1 message section of tsim_l1caltrack.

############################### Level 1 Track Trigger (WBS 1.2.3) -- M. Narain

> Work on integrating the firmware for the backend with the equations in
> the high pT bin continued.
>
> The DFEA prototype boards were received back from the assembly house.
> A first look at the boards seems to be okay. Power supply,
> Boundary-Scan chain and mechanical matching all work fine. The tests
> will continue in January.

############################### Silicon Track Trigger (WBS 1.2.5) -- U. Heintz

> With the Layer 0 silicon addition now part of the new baseline, the
> STT upgrade was reactivated. Orders were placed for some of the
> additional parts needed for instrumenting Layer 0 in the STT.

############################### Trigger Simulation (WBS 1.2.6) -- E. Berberis, M. Hildreth

> New plans have been drawn up for the next round of simulation using
> the new trigger system. The preliminary goal is to have new simulation
> results in a variety of physics channels using code that combines all
> of the upgraded trigger simulations by early summer. Milestones on the
> way to this goal and beyond are under discussion.
>
> Work continued on enhancing the simulation to optimize the performance
> of the CTT algorithm. In December, detector equations were established
> with correct CFT light yields and thresholds, and work was begun on
> background rate studies with these equations, working towards
> specifying FPGA requirements.

II. **DAQ/Online (WBS 1.3) Schedule and Budget information-- S. Fuess**

Activity in December 2003 was centered on the commissioning and testing
of multiple components of the storage and server systems for the Run IIb
DAQ system. A combination of items purchased for development studies and
the first Run IIb equipment purchase was configured. Initial
compatibility and performance tests are encouraging. Near term efforts
will focus on more network and storage I/O testing and on installation
of an ORACLE database in this environment.

############################### Level 3 Systems (WBS 1.3.1) D. Chapin, G. Watts

> There was no scheduled activity in 1.3.1 for the month of December
> 2003. The next scheduled tasks are 1.3.1.1.2.x, starting 4/1/04, for
> the evaluation of Linux farm nodes for a summer 2004 purchase. This
> purchase will use Run IIa operating funds, but is seen as a model for
> the 2005 purchase of Run IIb nodes.

############################### Network and Host Systems (WBS 1.3.2) -- J. Fitzmaurice, S. Krzywdzinski

.

> Storage Systems:
>
> 1.3.2.4.2.1 - The components of a Fibre Channel SAN - an FC switch, an
> FC JBOD disk chassis, and associated host bus adapters -- were
> purchased and installed as part of Run IIa Operations R&D. The final
> components arrived on 11/3/03. This task, 1.3.2.4.2.1, scheduled to
> begin 9/16/03 but actually starting 11/3/03, is for the operational
> evaluation of this SAN equipment, leading to a purchase in Spring
> 2004. In December 2003 all of the above components were connected to
> the DAQ Host secondary system (see 1.3.2.6) and configured. Testing is
> in progress, with performance as expected. With the success of testing
> to date, the successor tasks are expected to be completed as per the
> schedule.
>
> 1.3.2.4.3.1 - This task is for an evaluation of RAID components in
> advance of a larger purchase in Spring 2004. As with task 1.3.2.4.2.1,
> the final components of a Run IIa Operations R&D effort were assembled
> with the last remaining components arriving 10/31/03. Scheduled to
> begin 9/16/03, this task actually began 11/1/03 with the installation
> of a complete RAID array. Progress in configuring and testing the
> array has been excellent. During December 2003 the array was connected
> to the SAN infrastructure of 1.3.2.4.2.1 and the DAQ Host of 1.3.2.6.
> Initial tests have demonstrated the expected performance. The
> completion of this evaluation task remains on schedule for 4/12/04.
>
> DAQ Host Systems:
>
> 1.3.2.6.5 - This Operating task represents the effort required to
> operate a DAQ Host secondary system commissioned in November 2003.
> This system is being used to test the SAN and RAID systems of
> 1.3.2.4.x. A low level of system management effort is required to
> perform configuration changes and software updates.
>
> ORACLE Systems:
>
> 1.3.2.7.1 - One function of the Host Linux server system is as a
> platform for an ORACLE database. This task, in progress since 7/1/03,
> has evaluated the operation of ORACLE on a Linux server. The task was
> scheduled to complete on 12/19/03. Effort on this task has been
> manpower limited, and before the successor task, 1.3.2.7.2, of
> ordering a dedicated ORACLE server proceeds we would like further
> study. We have installed ORACLE on a RedHat 7.3 system, but have not
> yet done so on the Fermi LTS 3.0 (equivalent of RedHat ES 3.0)
> operating system version currently on our DAQ Host system. We expect
> the completion of this task to be delayed until 2/27/04, by which time
> we expect to have installed Oracle 9i on a Linux LTS 3.0 server.
> Successor tasks, 1.3.2.7.2 and 1.3.2.7.3 will be shortened in duration
> to maintain the milestone 1.3.2.7.5 date.
>
> File Servers:
>
> 1.3.2.8.1, 1.3.2.8.2, 1.3.2.8.3 - These tasks are for the evaluation,
> purchase, and delivery of a Linux File Server node. The original
> schedule has the delivery of this node scheduled for 12/5/03. As the
> File Server node is expected to be nearly identical to the DAQ Host
> node, and will make extensive use of the SAN, we would prefer to
> continue tests on the DAQ Host node before making the purchasing
> decision. No problems have been noted, but the complete sequence of
> tests is not yet complete. As a result, the evaluation task
> (1.3.2.8.1) is to be extended by 22 weeks to 1/26/04. We expect the
> eventual milestone in this chain of tasks, active use of the File
> Server (1.3.2.8.5) to be delayed accordingly. The only successor to
> this milestone is a 48-week evaluation period, which can be reduced to
> keep subsequent activities on schedule.

# Schedule Variance Analysis (as of 31 December 2003)

Schedule variances are reported against director's milestones in section
2. One milestone has already been successfully achieved. All remaining
milestones are projected ahead of the DOE baseline dates except for the
Cal Trk-Match milestone that was discussed earlier. No Level 2
milestones had slippages in the last month.

1.  **D-Zero Run IIb Trigger Upgrade (WBS 1.2)**

```{=html}
<!-- -->
```
1.  L1 Trigger TAB/GAB Prototyping Complete. Gained18 days in one month.

> This was due to correcting last month's schedule update which
> erroneously showed a 19 day slippage in one month.

2.  L1 Central Track Trigger Production and Testing Complete. Gained 41
    days in one month. Again this was caused by an erroneous update in
    last month's report.

############################### 3. D-Zero Run IIb Online (WBS 1.3) {#d-zero-run-iib-online-wbs-1.3 .unnumbered}

There is no unfavorable schedule variance for WBS 1.3

############################### Department of Energy Milestones (as of 31 December 2003)

The milestone for freezing mechanical parameters for the new silicon
Layer 0 project was completed on December 16, 8 days ahead of schedule.
