**February 2005**

############################### 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 3+ 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 

All production hybrids have been burned in at KU and shipped to FNAL.
All production digital jumper cables have been received from
Compunetics. The 1% test stand has been moved to Lab C and work has
started to read out up to 48 channels (the full L0). Mechanical, thermal
and flow measurements were made on the L0 support structures and
analysis of the data is underway. Design of fixturing for module
installation progressed and designs for the fixturing for installing the
Layer 0 in the DZero detector were developed and will be pursued both at
FNAL and U. Washington.

The Production Readiness Review for the ADF was held on February 11^th^.
No changes to the preproduction version of the board were suggested, and
the board went into production Feb 18^th^. The first assembled
production boards are expected back during the first week of March.

Meanwhile, the EM algorithm in the TAB firmware is being debugged. A
TAB/GAB crate + TAB board + GAB board + all the ADF to TAB cables were
sent from Columbia to Fermilab for the integration tests on the
sidewalk.

The Cal Track-Match testing found some problems with two of the UFB
boards and they were returned to the assembler. There are also problems
with the JTAG testing of the MTCxx and this has generated some schedule
slip. The crate manager testing was successfully completed and this
board is now ready to be tested at DZero. The DFEA2 boards of the L1CTT
upgrade passed their Production Readiness Review on Feb. 14^th^ and the
boards are going into production. Two DFEA2 boards have been tested on
the platform. The old and new DFEA boards (RunIIa and RunIIb versions)
give identical results with identical inputs using the RunIIa (doublet)
algorithm. The next step will be to put singlet equations in the new
board. Testing of the L2 Beta boards with fake inputs at 1 kHz was done
during two weeks of continuous operation. New firmware for tracking
events as they arrive at the Betas was verified during this testing.

Much of the trigger simulation software needed to simulate the Run2b
trigger is now in preliminary version. Data from a special run at higher
luminosity was taen for the trigger rate tool verification.
Extrapolations from lower luminosity data are in reasonable agreement
with higher luminosity data, giving some confidence in the validity of
the results. Testing continued on the AFEIIt prototype board. Testing of
the TripT prototype chips are complete and the chip will be ready for
production submission soon.

In the online group, plans for upgrading the L3 nodes were finalized and
a purchase for 96 new nodes was submitted. Infrastructre upgrades needed
to install the nodes were begun. Orders for the additional CPU needed
for the server and host systems have been placed. Disk storage options
are being studied. Approximately half of the control system upgraded
PowerPC's were in hand in the beginning of February and and order was
placed for the remaining SBC's.

############################### Project Milestone Summary (as of 28 February 2005)

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.

Table 1 shows the difference in the current forecast and last month's
forecast for achieving the DOE milestones. This table lists approved 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 -- V. O'Dell

A Director's review of the DZero RunIIb upgrade project was held
February 4-5. We are working on incorporating the comments from the
review. In particular, including the L0 installation fixturing into the
project is being done and canvassing the project to see where money can
buy schedule is ongoing.

The ADF passed its PRR on Feb 18^th^ and has gone into production. The
L1CTT DFEA2 boards passed their PRR on Feb 11^th^ and is also going into
production. The AFEII project has now gone through the internal DZero
reviews and we are working on scheduling a Director's review.

# Procurement Highlights -- V. O'Dell

The L3 node procurement started in February (\$200k). The PowerPC
procurement was also started in February (\$100k). We are planning to
updated the University of Washington's MOU/SOW to reflect adding the
installation tooling. This will likely cost about \$80k

############################### Trigger Highlights (WBS 1.2) -- B. P. Padley, D. Wood

There was significant progress on all subtasks during February. The last
board for the calorimeter trigger upgrade was released for production
after a successful review. Likewise, the main component of the CTT
upgrade, the DFEA2 board, was approved for production.

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

> The Production Readiness Review of the ADF v2 boards was held on
> February 11. The review committee was satisfied with the board design
> and the tests on the pre-production versions. They had no
> modifications to suggest and the boards were therefore released for
> production on February 18^th^. We expect the first few assembled
> production boards to arrive at MSU during the first week of March with
> the rest of the boards showing up one to two weeks later.
>
> Nevis continued work on implementing the new EM algorithm in the TAB
> firmware. A first attempt at this implementation was tried, but was
> found to have unexpected behavior. Solutions to these are being
> pursued.
>
> In anticipation of the upcoming integration tests at Fermilab, a
> substantial fraction of the TAB/GAB system hardware was shipped to the
> Lab. This shipment included: the TAB/GAB crate, a TAB, a GAB, and all
> the ADF-to-TAB cables.
>
> Work on the Run IIb L1Cal infrastructure also continued at Fermilab
> during February. Power distribution to the area was completed and work
> started on equipping the five Run IIb L1Cal racks with crates and rack
> monitor interfaces.

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

> Bench (loop) testing of the first production MTCM crate manager was
> completed. We will next test this card in the L1CalTrack crate at D0
> during spring break. The UFB flavor boards were assembled. JTAG
> testing found two bad cards that were returned to the assembler. JTAG
> testing of the production MTCxx cards ran into additional problems.
> This testing is complicated because of the numerous JTAG chains on the
> board with many devices.

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

> **DFEA2 -** DFEA2 passed the production review readiness on Feb 14th.
> As a result, we obtained quotes for the production parts and started
> to place orders. As expected, the item with the largest lead time -- 8
> weeks- are the power converters. The minor modifications to the
> production version of the board layout were completed. Quotes for
> production of PCB were obtained and the order placement process was
> initiated with the BU purchasing office**.**
>
> **In-situ testing Status --** Two DFEA2 boards have been tested on the
> platform. With fibers and cables mapping resolved, the old (DFEA) and
> new (DFEA2) boards give identical results to identical inputs (for
> doublet equations). This is an important step in confirming the
> satisfactory operation of the new board. The next step is to put on
> singlet equations onto the new boards.
>
> **Test Stand --** Work has started to understand the software and test
> procedures needed for testing of the production boards at FNAL. With
> the addition of Norik Khalatyan (BU), commissioning prospects have
> picked up, although the L1CTT group still seeking additional postdoc
> support, presumably from Fermilab.

############################### Level 2 Beta (WBS 1.2.4) -- R. Hirosky

> Tests continued of the new Beta with fake data (two weeks of
> continuous operation at an event input rate of \~1KHz). Data were
> continuously processed through the L2 calorimeter jet and electron
> algorithms with no errors. The fake events generate a factor of 10 or
> more objects than real data, and no slow downs or processing glitches
> were observed.
>
> New firmware from Orsay was verified during the above tests. This
> firmware provides a new tool to track events received by the Betas as
> they arrive in pieces from multiple broadcast sources.

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

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

> There was significant progress on the L1CTT and L1Cal simulators
> during this month focused on improving the underlying IIa trigger
> simulator framework software. A preliminary version of the new L1CTT
> simulator (in its IIa incarnation) was released and is foreseen to be
> available for further testing in March. The design of the interface to
> the IIb equations was also briefly discussed. The L1Cal simulator was
> interfaced with the L1CalTrack simulator. Testing is underway from the
> L1CalTrack side. The next step in the work on the L1Cal simulator is
> the interface to L2. A proposal and a commitment was made to write a
> first version of the new L2 software which interfaces to L1Cal by
> April, when we hope to have a first version of all simulators
> (excluding L2STT) as an integrated chain.
>
> Work has also progressed on the trigger terms studies using the
> trigger rate tool. A new run, taken at a higher luminosity, is now
> available for the calculation of the predicted rates at 20E30. We
> compared the rates estimated with the old run to the rates estimated
> with the new one and found reasonable agreement, indicative of no
> deviation from linearity in the extrapolation of rates to higher
> luminosity. We documented the electron algorithms studies in a D0
> internal note, and concentrated on the study of trigger terms
> containing jets: either multijet, or jets plus a muon. We used the
> trigger rate tool on Monte Carlo simulation in order to estimate the
> efficiency of the different terms on different signal samples.

############################### Analog Front End II (WBS 1.2.8) -- A. Bross

> Testing continues on the AFE II prototypes. All the boards (21) have
> now been loaded and will be available for test and evaluation. Testing
> and evaluation of the TriPt prototype chips is complete. Only one
> change (output buffer amp) has been identified for the engineering
> run. We will be ready for submission in March. Actual March submission
> will depend on approval from the Fermilab Directorate.

I.  **DAQ/Online Highlights (WBS 1.3) -- S. Fuess**

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

> During February 2005 we finalized plans for the purchase of nodes for
> the Level 3 processing farm. A requisition for 96 nodes, at a cost of
> \~\$200K, was submitted. The requisition package, modeled on Computing
> Division offline farms purchases, included the complete specification
> and bid package. \[The requisition was approved at all levels on
> 21-Mar-2005, and is now in the hands of Fermilab Purchasing.\] We also
> initiated the infrastructure improvements required to support the new
> nodes, with an electrical upgrade \[scheduled on 28-Mar-2005\] and air
> conditioning upgrade \[completed 10-Mar-2005\].
>
> We also continue to follow the performance metrics for the Level 3
> filter code, in consideration of a possible need for Level 3 computing
> capacity beyond the 96-node purchase now in progress. New versions,
> each with incrementally greater functionality yet better performance,
> are being introduced approximately monthly.

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

> **Control and Monitoring systems: 1.3.2.2, 1.3.2.3**
>
> There were no scheduled tasks in this area during February.
> Considerable operational experience with the new systems is being
> obtained with the current system.
>
> **Storage, DAQ Host, ORACLE, & File Server Systems: 1.3.2.4, 1.3.2.6,
> 1.3.2.7, 1.3.2.8**
>
> We continue to improve the operational performance of the Linux
> Cluster systems that are the backbone of the central computing
> functions. Problems with the RedHat Cluster software that we utilize
> have been addressed in recent updates. We are migrating to the latest
> version as opportunity allows. In general, these central systems are
> now operating extremely well, supplying adequate computing capacity
> with a high degree of reliability.
>
> The complete RunIIb plan calls for an augmentation of the minimal
> central system configuration now in operation. Six servers are being
> added to the four operational clusters (DAQ, Database, File Server,
> and Online functions). The new servers will provide the computing
> capacity needed for the duration of RunIIb, plus give a much-needed
> configuration flexibility. The requisitions for the purchase of these
> systems and peripherals were submitted in February. \[The systems have
> been ordered, with delivery expected 18-Apr-2005.\]
>
> We are also investigating the options for completing the disk storage
> requirements. We have quotes for a variety of system configurations
> and vendors, and are studying the characteristics of each system. We
> expect to make storage purchases in April, 2005.

############################### Control Systems (WBS 1.3.3) -- F. Bartlett, G. Savage, V. Sirotenko

############################### We are in the process of purchasing Motorola PowerPC mv5500 processors for the Control System upgrade. Approximately 50% of the new nodes were in hand at the beginning of February. A requisition for the remaining nodes was submitted in February \[and has been in the hands of Fermilab Purchasing since 17-Mar-2005\]. {#we-are-in-the-process-of-purchasing-motorola-powerpc-mv5500-processors-for-the-control-system-upgrade.-approximately-50-of-the-new-nodes-were-in-hand-at-the-beginning-of-february.-a-requisition-for-the-remaining-nodes-was-submitted-in-february-and-has-been-in-the-hands-of-fermilab-purchasing-since-17-mar-2005. .unnumbered}

############################### DAQ/Online Management (WBS 1.3.4) -- S. Fuess

> the DAQ/Online subsystem.

II. **Silicon Detector Layer 0 Highlights (WBS 1.6) -- A. Bean, R.
    Lipton**

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

> All production hybrids have been burned in at KU and shipped to
> Fermilab. In total, about 100 hybrids are ready to be used for the
> module production. All production digital jumper cables have been
> received from Compunetics. Evaluation of the cables is in progress.\
> \
> Three racks with 1% test stand have been moved into the Lab C clean
> room and work started to set up all necessary infrastructure to read
> out up to 48 (whole L0) channels. The stand is located in the vicinity
> of both the L0 assembly table and the prototype support structure with
> 10 mounted L0 modules so can be used to readout both.

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

> Dimensional and load measurements continued on the second layer 0
> support structure. Programs developed for analysis of the first
> support structure were transferred to Kansas State University, where
> analyses of coordinate measurement machine data of the second
> structure will be done. Thermal and flow measurements were completed
> on both Layer 0 support structures. Analysis of the measurements
> should be completed shortly.
>
> The design of fixturing to hold the support structure during module
> installation progressed well. Except for details of end rings for the
> support structure rotating fixture, designs were completed and
> prepared for fabrication. Fixtures to install sensor -- hybrid modules
> on the L0 support structure were received. CMM measurements of
> connector alignment on hybrids and other hybrid mechanical parameters
> were made. Techniques to align cables on hybrids were reviewed in
> order to accommodate the precision with which the connectors are
> aligned.
>
> Dimensions for final spacers to position hybrids were proposed and
> distributed for comment. Spacers will be ordered as soon as comments
> are evaluated.
>
> Procedures and tooling to install L0 at D0 had been discussed in a
> joint Fermilab and University of Washington meeting. Two approaches
> for fabricating the main Layer 0 installation tool were developed.
> Both approaches will be pursued, one at Washington and the other at
> Fermilab, in order to ensure that a sufficiently accurate tool will be
> available at the earliest possible time.
>
> As a side-effect of BTeV cancellation, a significantly increased level
> of engineering support became available for Layer 0. A tentative
> matching of task assignments and technical personnel was developed in
> order to ensure the new personnel will be used effectively. The
> increased level of technical support should be significant in ensuring
> that Layer 0 will be completed on schedule.

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

> The HV power supply problems reported last month were due to loose
> connections on the crate backplane. One HV crate, with a complete
> compliment of pods, has been installed in the test stand at SiDet. The
> other HV crate is ready for installation in MCH2.
>
> The LV isolated power supply system at SiDet is operational. The
> supply is configured to provide power to the Interface Board and the
> Adapter Card. Readout tests can now be performed through the entire
> system rather than with only with a 'purple card'.

# Schedule Variance Analysis (as of 28 February 2005)

Schedule variances are reported against director's milestones in section
III. Nine milestones have already been successfully achieved. All
remaining milestones are projected ahead of the DOE baseline dates.

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

> The Cal Track-Match upgrade lost 16 days in the last month due to
> problems found during testing of the boards. However, this upgrade is
> currently scheduled to end on June 1, 2005, well ahead of the shutdown
> schedule, so there is some slack in the schedule. We will continue to
> closely monitor it's progress. The L2 Beta lost 37 days in the last
> month. However considerable progress has been made and the board that
> is now under test appears to work well. The L2 Trigger upgrade
> milestone slip of 33 days in the last month is just a reflection of
> the L2 Beta upgrade slip.

2.  **D-Zero Run IIb Online (WBS 1.3)**

There is no unfavorable schedule variance for this subproject.

############################### D-Zero Run IIb Layer 0 Upgrade (WBS 1.6)

There is no unfavorable schedule variance for this subproject.

############################### Cost Performance Report (as of 28 February 2005)

This report is generated from COBRA and provides a summary of the WBS
1.2-1.4 costs of the Project down to Level 3 of the Work Breakdown
Structure. Silicon detector subproject closeout costs are not tracked
here. Input data originates with the status (% Complete) of the Project
schedules as reported by the Level 2 managers and actual costs extracted
from the Fermilab accounting system. Where possible, costs are accrued
for items that have been delivered, but not yet invoiced. Financial
summaries are shown for this reporting period (columns 2-6) as well as
the project to date (columns 7-11). Column 12 contains our baseline BAC,
and will only be changed after the formal implementation of the Change
Control process. Column 13 is the projected BAC, based on the current
month's schedule.
