############################### 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 

Strip testing at Stony Brook continued. The four Layer 0 readout chains,
installed into DZero during the shutdown, were successfully read out.
More hybrids were produced and some full chain testing done using
production twisted pair cables, production HV/LV cables and prototype
digital jumper cables, with the aim to verify the performance of all the
components and to sign off on the new jumper cables. Electrical tests
with several prototype modules being read out simultaneously are
underway. The Layer 0 carbon fiber support structure, shipped from
University of Washington last month, has been visually inspected and
measured. Mechanically it is within specifications. The only flaw found
on the structure is a local loss of gold plating at one hybrid mesh
grounding circuit. The final LV Power Supply system for the Layer 0 was
completed and partial operational readiness clearance was obtained. Some
H-disk cable reorganization was done during the shutdown in order to
make installation of the new Layer 0 adapter cards easier.

For the trigger upgrade, fabrication and assembly of ten ADF v2 boards
started in November, and the boards are expected back in mid-December.
The production TAB/GAB boards are also being assembled and are expected
back at the end of December. Final measurements of the prototype
BLS-to-ADF transition system were made and production of the final
BLS-to-ADF system is expected to begin in January. The production Cal
Track-Match Universal Flavor Boards were submitted for fabrication and
the rack infrastructure was reconfigured during the shutdown. For the L1
CTT, more testing of the DFEM/DFEA board continued in November. Some
bugs were found and fixed in the firmware. One board was installed in
the DZero detector and read out through the normal readout chain. The
board is working well and tests are continuing. A new SBC for the Level
2 Beta upgrade has been bought and, so far, tests show that it is easier
to use than the Concurrent SBC's. In addition to hardware work,
algorithm development is moving along -- we will need new algorithms
with good rejection at L2 once the new L1 cal trigger goes in. The
decision about the STT upgrade was postponed until December. The trigger
simulation group has been very active. The optimal electron algorithm
for the L1 Cal was agreed on by the simulation, physics and hardware
people. The simulation software itself is progressing, with the idea of
getting all the RunIIb trigger simulation software integrated in the
DZero trigger simulation package trigsim. The AFE prototyping is going
along -- the new TriPt prototypes are fully functional, and it looks
like no design changes are needed. The critical path for the project is
now the AFE IIt prototype board.

The online system server system backbones were all successfully
installed during the shutdown. The migration of Online operations to the
Linux servers from the current Alpha servers was successfully completed.
The DAQ rates were measured and are as expected. The control systems
(Motorola PowerPC 8500 processors) have been successfully tested, and
the full complement will be ordered for the summer shutdown.

############################### Project Milestone Summary (as of 30 November 2004)

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 VIII of this report.

############################### Management Highlights -- V. O'Dell

After careful consideration, it was decided not to go forward with
additional Track Fit Cards for the Silicon Track Trigger. The decision
came out of the STT review held on September 10^th^, and with follow up
information asked for by the review committee received in October.
Additional boards are still needed to receive the L0 signals and these
will be built. The Track Fit Cards basically add more processing power
to the system, and it was decided that this would not be needed. A
change request has been generated.

The Silicon L0 module PRR was held on November 24. The PRR, committee
report, and response from the project can be found at:

**http://d0server1.fnal.gov/projects/run2b/Silicon/www/smt2b/Documentation/Reviews/L0_module_PRR.htm**

The committee was fundamentally satisfied with the preparations and
planning but had some comments and suggestions that were agreed to by
the project.

# Procurement Highlights -- V. O'Dell

All major University MOU/SOWs are now in place until the end of the
project. The University of Notre Dame (\~\$40k) is still in the works.
Some major procurements for the L3 nodes for the online systems are
expected in March.

> location of sensor mounting surfaces averages 0.041 mm below design
> for A-layer sensors and 0.093 mm below design for B-layer sensors.
> Those deviations would provide slightly increased clearance during
> installation of Layer 0 at D-Zero. Standard deviations from a plane
> are 0.028 mm for A-layer sensor locations and 0.044 mm for B-layer

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

The accelerator shutdown work concluded in November. The installation
was completed of a complete parallel chain of upgrade electronics for
the Level 1 CTT, and in situ testing was begun. The infrastructure
installation for the Level 1 cal-track system was also completed. This
work during the shutdown will allow in-situ testing of these systems in
the coming months which should be a significant advantage in speeding up
the commissioning of the final systems.

Modules in final production now include the TABs and GABs for L1cal, the
MTCxx & UFB for L1caltrack, and the crate controllers for L1CTT.

Productive simulation workshops yielded a finalized algorithm for
Electromagnetic triggers in the L1cal.

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

> Fabrication and assembly of ten ADF v2 boards at Adco started in
> November with the boards expected back in mid December. Assembly of
> the production TAB's (10) and GAB's (3) also started at the end of
> November. These boards are expected back at the end of December as
> well.
>
> Firmware work on the TAB's and GAB continued this month. In
> particular, a new, simpler synchronization scheme has been implemented
> for data from the ADF. This scheme does not rely on initialize signals
> from the trigger framework and will thus make testing the system
> significantly easier than the old scheme. Work was also started on
> implementing the new EM algorithm that was chosen last month.
>
> At Fermilab, final measurements were made on the prototype BLS-to-ADF
> transition system. Values for termination resistors on the ADF
> receivers were determined and the entire transition system was
> certified by MSU and Fermilab engineers. Final documentation for the
> system will be made available in December and production of the full
> system will start shortly thereafter.

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

> The production MTCxx cards were assembled. JTAG testing of the
> prototype board was previously unsuccessful and we are continuing to
> investigate the problem using production boards. (This does not affect
> the operation of the boards in any way.)
>
> The production UFB boards were submitted for fabrication.
>
> Some work was done reconfiguring the rack services in MCH1.

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

> **DFEM/DFEA Integrated Motherboard/Daughterboard (aka DFEB):**
>
> In November, some bugs were fixed in DFEB firmware. Three more DFEB
> boards were tested: one board passed all tests, another has one signal
> not properly soldered and needs rework, and one board has its PCB
> delaminated and has too many connection problems to be fixed. In all,
> we think that the current merged MB/DB scheme should be a viable
> solution. The separate daughterboard + motherboard scheme may have
> more problems in the long run. A second DFEB was mailed to FNAL from
> BU.
>
> **In-situ testing Status:**
>
> A DFEB board has been installed on the west platform underneath the
> DZero detector. We are able to initialize this board with no problems.
> A 9th CTOC board has also been installed and connected to the DFEB
> outputs. The Level-3 output of this CTOC feeds into our readout crate
> 0X13. The DFEB has been \'dialed in\' to the SCL timing and now shows
> perfect agreement between the embedded control bits coming from the
> AFE/MIXER and the SCL. The installed DFEB appears to have no problems
> with its inputs and it is generating what appears to be a properly
> formatted output record. We are beginning to exercise the input/output
> capture buffers now. These capture buffers have already helped to
> uncover a two crossed cables, which explains why the DFEA and DFEB
> output records to not match exactly.
>
> **Download Software:**
>
> Geoff Savage has developed a driver that interfaces EPICS to a NIC
> card in a PC running Linux. The Linux box is an EPICS input/output
> controller (IOC) and functions just as the embedded processors do.
> Currently developing a template that maps the hardware registers to
> EPICS records for monitoring. Once this is finished, Geoff will make
> the firmware download application a channel access client. Channel
> access is the protocol one uses to talk to an IOC.

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

> In algorithm development, students at MSU and NIKHEF are continuing
> their studies of L2 missing ET and B-tagging. Both expect updates to
> be ready for December.
>
> Regarding the firmware impact of the new SBC's, we set a meeting to
> discuss firmware and firmware/software interfaces this month. Minor
> firmware updates were identified to facilitate the support of multiple
> worker nodes in a single L2 crate. This is independent of the SBC
> used. No changes are required to support one SBC over another.
>
> Processor operability in Beta motherboards is still being evaluated. A
> new SBC was acquired this month from Adlink Technologies. This SBC is
> preferable to the Concurrent Tech SBC we have been evaluating for
> several reasons (1) Simpler interface, no mezzanine connection for
> power/etc (2) lower power consumption. This SBC will require us to
> build a small passive adapter card for the hard drive. Parts have been
> purchased and the card will be designed at UVa next month.
>
> We have made much greater progress with this board and uncovered a few
> unexpected problems with our previous tests:

-   an extender card used to mount the new SBC's to the motherboard was
    found to have broken traces.

-   a pin used to enable cPCI system controller boards needed to be hand
    soldered to ground on the Beta motherboard

-   poly switch current limiters on the motherboards were found to be
    slightly underrated for the power requirements of the new SBC's,
    leading to voltage drops on the power lines. Replacements have been
    purchased for use w/ new SBC's.

> The new Adlink SBC has been observed to configure the PCI-based
> devices on the Beta mother card and has successfully entered the boot
> sequence from the BIOS. We will design a small hard drive adapter to
> proceed to booting the OS. In the mean time, we will try to fully boot
> the new SBC in a mothercard using an active extender card and
> PMC-based hard drive adapter to complete the tests.

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

> A decision not to produce any more Track Fit Cards, but to continue
> with the STT upgrades needed to incorporate the Silicon Layer 0
> signals into the STT trigger was made. A change request has been
> generated.

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

> Progress has been made in integrating the L1Cal and L1Caltrack into a
> trigsim executable. A skeleton of the L1Caltrack simulator has been
> integrated within trigsim, with correct messaging to L1 and L3. The
> University of Arizona is now working on the implementation of the
> algorithms, on analysis tools, and on the implementation of L1Caltrack
> trigger information in the data.
>
> York University has made progress towards integration of the L1Cal
> simulator into a trigsim (although an executable is not available).
> Preliminary L1Cal to L2Cal data structures for trigsim have been
> prepared, based on the current description of the L1Cal hardware. Work
> is progressing towards the IIa rewrite of the L1CTT simulator which
> will be used for IIb as well. We have identified the need for manpower
> to work on the development of L2Cal algorithms.
>
> We have converged on the optimal electron algorithm for L1Cal and have
> a working version of the trigger rate tool with IIb Cal terms
> implemented. We plan to use such tool to estimate preliminary trigger
> terms for a straw-man trigger list. We are working with the
> collaboration to identify additional people to study the straw-man
> trigger list by the beginning of next year.

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

> Testing continues on the AFE II prototypes. The following
> functionality has been tested and verified: FPGA/TriP/ADC power
> turn-on, regulators and monitor, Bias setting circuits and code, ADC
> circuits and code, 1553 controller communication, PIC to FPGA
> communications, FPGA to TriP serial download, and the TriP clocks.
> Work continues on FPGA code debug. The TriPt prototypes have now been
> tested and are fully functional. Although testing on these parts will
> continue, we do not believe that any design changes are needed for the
> production submission. The critical path for the project is the AFE
> IIt prototype board. We still are having problems getting all the
> manpower for the project on-board.

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

The Fall 2004 accelerator shutdown officially ended this reporting
period. During the shutdown we have successfully transferred the Online
host system activities to a set of new Linux clusters. Data taking has
resumed.

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

> There were no scheduled tasks in this subproject during November 2004.
> Operation of the most recent Level 3 farm node acquisition continues
> without problem. The next activity in this WBS is another farm node
> acquisition, with the process to begin in Spring 2005.

############################### 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 November. The most
> recent activity was the installation and commissioning of new systems
> purchased over the summer. These systems are now active and part of
> the standard operations of the Online 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 now have four operational clusters for DAQ, database, file serving,
> and general "service" (web, alarms, electronic log) functions. We made
> the transition of the development and production Oracle systems to the
> new cluster in late October. The host level "event handling" functions
> -- data logging, cataloging, and storage -- were successfully migrated
> to a Linux cluster in November. DAQ rates have been measured and are
> as expected -- approximately 30 Mbytes/sec to a single stream and from
> 50-60 Mbytes/sec to multiple streams. The new NFS cluster is in full
> use; we have surmounted several problems noted with the current
> version of the Linux kernel. We have successfully completed the
> migration of Online operations to the Linux servers from the current
> Alpha servers within the Fall shutdown period.

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

# Schedule Variance Analysis (as of 30 November 2004)

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

1.  **D-Zero Run IIb L0 Upgrade (WBS 1.6)**

> The L0 module complete milestone slipped 47 days in November,
> basically due to delays in scheduling the module production readiness
> review and conflicts with the holiday schedule. This did impact the
> final milestone for the L0 ready to move to DAB, delaying the
> readiness date by 10 days. We might be able to make this up with a
> more aggressive module production schedule.

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

> The L1 Calorimeter Trigger Production and Testing Complete milestone
> slipped 20 days in the last month due to the ongoing slips in the
> ADFv2 board. However, the board is now in fabrication. We are also
> combing through the MPP schedule and relating it to our experience
> over the last year to get a new estimate for completion of the ADF. We
> should have more information in January in order to understand how
> reliable the schedule really is.

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

############################### Cost Performance Report (as of 30 November 2004)

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
