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

This month the project learned that the Tevatron shutdown date,
originally tentatively scheduled for October 31, was moved to March 1.
This has a major impact in the project and the project schedule, and the
subprojects are now grappling with how to handle this four month
installation delay.

As reported in the August monthly report, readout testing of the full
Layer 0 detector confirmed that coherent noise was coming from the RTD
cables and in September connector cards were designed to tie the RTD
cable shield to ground. These cards are now ready for assembly.

With the delay of the shutdown, plans are being made to use the cosmic
ray stand at SiDet to do more testing of the L0 and the ORC is in
progress. Mock-up tests of installation of a layer 0 model were
successfully performed in Lab 3 and mock-ups of the downstream gap
installation were performed in DAB. Preparation to measure the radial
profile of the L0 was begun. Tooling to facilitate installation
continues and software to support the silicon test modules already
installed in the collision hall is being started.

Work continued on the testing and integration of the RunIIb L1 Cal
system at Fermilab. The transition system patch panels were completed
and the preproduction transition cards were received, successfully
tested and the rest of the cards were released for production. System
shakedowns continued along with comparison of simulated and real trigger
outputs. Much thought was put into the most productive use of the extra
time the shutdown delay generated. It was decided to push to make the
system operational and then include it in normal D0 running to get
operational experience with it.

Issues with measuring the L1 Cal-Track Match latency was traced to a bad
cable, and measurements with the L1Cal + L1 CalTrack Match were made.
Next month the latency measurement for the full chain
L1Cal-L1CalTrack-Trigger Framework should be made on the L1Cal sidewalk
test stand.

All the L1CTT hardware is complete and tested. Software to calculate
efficiency of the singlet equations is still being worked on. The plan
during the extended time before the shutdown is to continue running
platform tests to gain more experience with h/w and s/w. In addition the
new boards should be retested a few weeks before installation.

The L2Beta project is complete and ready for installation.

The L2STT hardware is also complete and additional work is needed on the
firmware and software for the system. Additional manpower is anticipated
in October to work on this.

The L1CTT simulator is maturing rapidly. Already it has resulted in
estimating trigger rates for single track terms and work to finishing up
and debug the code continues. The L1CalTrack simulation is also nearing
completion.

Packaged TripT chips arrived at the end of September and to verify the
design and packaging processes, one chip was tested in detail and worked
as expected. This eliminates the design risk issue, but the yield
measurement is waiting for completing the robot setup. A low yield could
require another cycle of TripT production. Stuffed AFEIIt boards arrived
at Fermilab in September and testing began. The boards work well with
only some minor layout changes needed.

############################### Project Milestone Summary (as of 30 September 2005)

The DOE baseline milestones, defined in the modified DOE Project
Execution Plan, are shown in Figure 1 as solid diamonds. Open are the
Project's forecast dates for achieving the milestones. Actual dates of
achieving milestones are shown as solid stars. The Trigger, Online,
Layer 0 Silicon, and AFE milestones are shown separately and sorted by
current forecast date.

Table 1 lists approved DOE milestone dates along with the project's

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

The Layer 0 Technical Readiness Review was held on September 27^th^ and
a copy of the review report is attached. The review was very favorable
and the reviewers felt that the detector would be ready to install at
the end of October, however given the installation delays, the reviewers
also felt the extra time would be useful to perform additional tests in
order to further minimize risks of installation and commissioning. One
of the issues being faced by the project is handling the delay of the
shutdown date. The delay in project installation is encouraging all
subprojects to put additional effort in testing and verifying their
upgrade piece, which will increase the labor cost of the project. This
is being examined in detail to determine what should legitimately be on
project and what should not, and formal change requests will be
generated in October/November.

# Procurement Highlights -- V. O'Dell

All of the large procurements are now over for the IIb project except
for the AFEII-t part of the project. The next large purchase will be for
the production order of parts for the AFEIIt scheduled for
November/December '05 (\~\$300k).

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

As of September the project was well on the path to being completed in
time for an October 31 shutdown of the Tevatron. This is well in advance
of the original baseline schedule and in line with the schedule updates
that were given to the lab last winter. Meeting this accelerated
schedule is an important achievement and allowed us to reaffirm our
readiness for installation.

Early in September, however, we received notice that the start of the
shutdown would be delayed until some time between January and March,
2006. This delay initiated a review of strategy in each of the
subsystems.

Generally, the strategy between now and the installation is to complete
any remaining pre-installation tasks on a time scale of a few weeks, and
then to gain operational experience in the next few months with the
parallel readout systems that are in place. In addition, some re-testing
of modules will take place just before the shutdown.

We are also working on ensuring that we have appropriate personnel in
place for installation and commissioning in Winter/Spring \'06. Some of
the people who were available for a Fall \'05 shutdown will not be
available in Winter/Spring \'06, so some shift of responsibilities will
be necessary.

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

> Good progress was made on the Transition System in September. The
> Patch Panels and their front panels were produced. However, the front
> panels proved to be slightly too wide and had to be machined down in
> the Fermilab machine shop. After this operation, the boards fit nicely
> in the crates.
>
> Eighteen ATC cards were received at Fermilab in mid-September.
> Fourteen of these were tested and were found to perform as expected.
> So the rest of the boards were released for production. Scheduling
> difficulties at the fabrication and assembly houses have caused a
> delay of a few weeks in the delivery of these boards.
>
> Work also continued on system integration at the Test Stand. Presumed
> timing problems in a TAB (the \"8\'s problem\" discussed at the
> Technical Readiness Review in August) were traced to a broken pin on
> the backplane corresponding to one of the ADF input lines. Progress
> was also made in comparing simulation with hardware results.
>
> Finally, we spent a significant amount of time planning how to deal
> with the delayed shutdown announced by the director early in the
> month. After considering several possible options, we have decided to
> push hard to have the system operational on essentially the original
> timescale (late-October - mid-November). The Run IIb L1Cal will then
> be included in global D0 running, using unused and/or terms at the TFW
> to allow us to examine up to 16 triggers. As data we will use the 4
> split TTs currently available as well as test patterns loaded into the
> ADF memories. The goal is to have the Run IIb L1Cal treated as just
> another D0 subdetector, with its operation controlled and monitored by
> the CalMuon shifter.

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

> Latency measurements including the new L1Cal trigger were performed.
> The delay in completing this measurement was traced to an
> intermittently bad cable. The full measurements of latency of the full
> L1cal-L1caltrack-Trigger Framework chain should take place next month
> using the L1cal sidewalk test stand.
>
> We developed a more sensitive test for cable integrity using eye

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

> The software to evaluate the efficiency for the singlet equations from
> the data taken with the split signals on the platform is evolving
> rapidly and continues to be shaken down. We expect to have efficiency
> measurements by the end of next reporting cycle. The software to
> generate equations for all sectors and multiple operating points was
> finished.
>
> The plan between now and the shutdown is to continue to run the
> sectors on the platform and to gain more experience with the new
> hardware and software. All DFEA2 cards should be individually tested
> again a few weeks before the actual shutdown begins.

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

> This project is complete, and ready for installation.

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

> No additional work was done on the STT in September. The remaining
> firmware and software work depends on simulation updates, for which we
> anticipate new manpower in October.

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

> Progress on the L1CTT simulator this month resulted in first estimates
> of trigger rates for the single track terms, with the new simulator in
> its 2b flavor. Work continues on debugging the new simulator, adding
> the isolated track terms, and completing the delivery of messages to
> L2, L3, and the trigger framework.
>
> Progress was made on the algorithms definition for L1CalTrack (for tau
> and electron objects). The L1CalTrack simulator (as well as a
> preliminary version of the L1CTT simulator) is ready for integration
> into a first version of the global 2b Trigger Simulator. L1CalTrack
> electron and tau objects are also available for use in the newest
> version of the Trigger Rate Tool.

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

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

> All Level 3 hardware system upgrades were completed in August. The
> only remaining work involves some continuing configuration activity to
> bring the new nodes into active DAQ use.

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

> **Online/DAQ Network: 1.3.2.1**
>
> All hardware purchases for this task were completed in August. This
> upgrade expands the gigabit networking capacity for the core servers.
> As the installation of these new components will disrupt the entire
> Online network for several hours, we are delaying installation until
> either an extended accelerator down time or the start of the shutdown
> period.
>
> **Control and Monitoring systems: 1.3.2.2, 1.3.2.3**
>
> The upgrade of the interactive control room and the event monitoring
> systems (replacing older out-of-warranty systems) is funded as part of
> the Operations budget. Sixteen new nodes were delivered in September,
> and will be installed, configured, and integrated into the Online
> system as needed. This completes the hardware purchases for these
> tasks.
>
> **Storage, DAQ Host, ORACLE, & File Server Systems: 1.3.2.4, 1.3.2.6,
> 1.3.2.7, 1.3.2.8**
>
> All hardware purchases for these tasks are complete. We continue to
> configure and integrate recently acquired systems into the existing
> Host clusters. This process is mostly proceeding on an as-necessary
> basis and when accelerator downtimes permit cluster reconfigurations,
> avoiding unnecessary interruption of data acquisition.

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

> The MVME5500 processor purchase for the control system upgrade is
> complete. We continue the process of installing the new processors.
> There are no outstanding issues.

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

> Layer 0 mechanical construction was completed at the beginning of
> August and full system readout tests began on August 14th.  These
> tests successfully concluded around September 15th.  Tests confirmed
> full operability of all detector modules.  During the testing we
> confirmed that toroid filters on the power supplies are needed to
> suppress noise when the detector grounds are isolated from the system
> ground.  With the delay of the shutdown, plans are being made to use
> the cosmic ray stand at SiDet to do more testing of the L0. Mock-up
> tests of installation of a layer 0 model were successfully performed
> in Lab 3 and mock-ups of the downstream gap installation were
> performed in DAB. 

############################### Readout (WBS 1.6.2) -- R. Sidwell, K. Hanagaki

> As a part of the full system testing, the HV scans, the bandwidth
> scans and the thermocycling tests were performed. All the results were
> consistent with what we expected. Readout testing with various
> configurations, such as sparsification, real time pedestal subtraction
> and so on, indicated no problems.\
> \
> We found that the shielding and grounding of the RTD cable suppressed
> the RTD noise image. Based on this finding, we started to design a
> small connector board for the RTD cable, where the shield can be tied
> to the ground.\
> \
> In readout testing at the DAB, the pedestal shift in a particular tick
> was observed. The correlation with preamp reset timing of SVX4 was
> checked, but there was no correlation. The source of this pedestal
> shift needs to be identified.\
> \
> In order to operate the four test modules installed in the collision
> hall continuously, a download GUI which controls both SVX2 and SVX4 is
> needed. The development has been started.

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

> Tests to verify space and fixturing to bring L0 to the outer end of
> the north end calorimeter and to insert it into the calorimeter beam
> tube were successfully completed. The procedures for that work
> incorporate a L0 transport container provided by the University of
> Washington. Multiple demonstrations of the procedures were conducted
> with observers from Fermilab and the University of Washington present.
>
> Measurements to verify the radial profile of L0 were begun at the end
> of September. Early during those measurements, the lens of the
> coordinate measuring machine (CMM) video probe collided with one L0
> sensor. Subsequent electrical tests showed that three strips of the
> sensor were shorted to one another, but that sensor leakage currents
> and performance were otherwise not compromised. All L0 CMM
> measurements were suspended pending the development of CMM operating
> procedures and measurement procedures and equipment which would ensure
> that L0 CMM measurements could be conducted safely. CMM operating
> procedures will be reviewed and approved by D0 and SiDet and approved
> by SiDet / PPD line management. New measurement procedures will be
> reviewed by and approved by both D0 and SiDet.
>
> The new beryllium beam pipe was wrapped with kapton insulation at five
> longitudinal locations to prevent direct electrical contact between
> the beam tube and the inner surface of the L0 carbon fiber support
> structure. Trial installations of the beam pipe into the spare L0
> carbon fiber support structure (CS1) were successful. Capacitive
> coupling between the beam tube and the support structure was
> consistent with expectations.
>
> The design of tooling to install L0 mounts on the ends of the Run IIa
> support structures was completed. The design of tooling to install
> junction card mounts neared completion. Both sets of tooling will be
> tested at Lab 3.

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

> Arrangements are being made to assemble the RTD filter cards. ORC
> documentation is in progress to acquire an ORC for the cosmic ray test
> stand at SiDet. Integration of the isolated low voltage power supply
> CAN bus monitoring system is currently underway. EPICS data base
> records are being generated. A python monitoring program is under
> development.

III. **Analog Front End Highlights (WBS 1.7) -- A. Bross, P. Rubinov**

```
1.  **TripT (WBS 1.7.4) -- L. Bellantoni**

> During Sept, we continued to prepare for the arrival of the packaged
> production TriP-t chips. They were sent to ASAT for packaging in the
> second half of August. Packaged parts finally arrived on Sept 25^th^.
> A couple of chips were immediately mounted on the same tester boards
> as the prototype TriP-t chips (not the robot test) and the chip(s)
> were tested to validate the design. The biggest risk would have been a
> systematic flaw on the production chips that would have required a
> redesign of the chip, remaking of the mask and, of course new wafers.
> The second highest risk was that there was a systematic error in the
> design of the packaging that would require a new set of wafers to be
> manufactured so they could be packaged again. The third highest risk
> was that the yield of the run was low and additional wafers would have
> to be purchased. Testing only one chip in detail eliminated the first
> and second highest risk factors. The yield testing will require the
> robot to test the chips in large quantity.

2.  **AFEII-t board (WBS 1.7.5) -- P. Rubinov**

> First boards arrived from the assembly house on Sept 6^th^. The boards
> were of very good quality, both the PCB and the parts assembly and
> initial work such as inspection and power up proceeded smoothly.
> During testing a number of design errors were discovered and fixed but
> in all cases so far the errors were easily fixed and will not affect
> the performance of the board. Our experience up to this point has
> validated the design methodology: critical areas of the board were
> checked carefully, and no errors were found- less critical areas and
> support functions were for the last and not checked as thoroughly in
> the interest of time and as a result some errors occurred, but these
> errors do not involve high speed signals or other critical circuitry
> and do not affect the performance of the boards. To fix the errors so
> far discovered on the production boards will require only minimal
> layout changes (and in many cases none).
>
> The board subsystems and functions tested during September include the
> following:

1)  All power applied (AFEI power supply values)

2)  1553 communications functional

3)  JTAG programming chain working

4)  RT1553 FPGA operating properly

5)  PIC microcontroller operating properly using new C code

6)  HELPER FPGA operating properly

7)  CLOCKGEN FPGA operating properly, clocks being generated, phase
    control from the PC, through 1553 is working properly. Operations
    checked in both local and remote mode and terminations were tuned
    for good signal quality.

8)  Program and read the FLASH memory

9)  The on board FLASH successfully used to program the 4 DFPGAs.

10) The on board FLASH successfully used to program the 8 AFPGAs.

11) ADC for measuring bias voltage and current and temp is working and
    being properly read out by the HELPER/microcontroller.

12) The muxes used to route signals to the ADC are working and properly
    set via 1553 and/or the microcontroller.

13) Bias DACs, heater DACs are working and all associated circuits
    (reference, op amps, filters) appear to work.

# Schedule Variance Analysis (as of 30 September 2005)

Schedule variances are reported against director's milestones in section
III. Fourteen milestones have been successfully achieved.

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

> In September, the decision to move the October 31 shutdown to March 1
> was made. As a result many of the final completion dates for the
> RunIIb subsystems slipped due to a desire to exercise the systems more
> thoroughly with the additional time. The forecast completion dates are
> well in advance of the shutdown date and in most instances well ahead
> of the L2 milestones.
>
> The L2STT lost 47 days in the last month due to lack of manpower for
> simulation work. While the simulation work is not part of the project,
> it is needed as input for the firmware and online software work needed
> for the L2STT to work. The simulation manpower is anticipated to begin
> in October. The STT milestone slippage also caused the L2 milestone to
> slip 35 days. Once we get a handle on when the STT simulation work
> will complete, we will make a change request.
>
> The L1 Cal-Track Match completion date slipped 65 days in the last
> month. Part of this delay came from delays in making the latency
> measurements (now done) and part comes from anticipating making for
> thorough tests and measurements, especially in better measurements of
> the cable integrity as that is what slowed down the latency
> measurements.
>
> The L1 Central Track Trigger completion date slipped 70 days in the
> last month. This time will be used to gain more experience in L1CTT
> running at DZero and to calculate efficiencies. All the boards will be
> retested closer to installation time.
>
> Due to the slips in the component L1 subsystems, the final L1 Trigger
> completion date slipped 68 days in the last month. The completion date
> is now December 2005, well in advance of the shutdown/installation
> date.

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

This subproject has completed its milestone.

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

> The L0 project had a schedule setback when the CMM machine collided
> with a sensor module during measuring. This effectively grounded 3
> sensor strips together and caused us to suspend all measurements and
> review measurement procedures. This cost about 10 days delay. In
> addition, due to the change in shutdown schedule, the L0 detector will
> be more thoroughly tested than originally foreseen. The final
> completion milestone has slipped 106 days in the last month in order
> to accommodate cosmic ray testing of the L0 detector, more testing of
> the grounding scheme, and additional tests using the SVX4 readout
> installed in DZero.

############################### D-Zero Run IIb AFEII Upgrade (WBS 1.7)

> The AFEII lost 3 days in the last month.

############################### Department of Energy Milestones (as of 30 September 2005)

############################### Cost Performance Report (as of 30 September 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.

Some salient features can be seen in the CPR. Of the cost overruns in
the L1 Calorimeter Trigger (\~\$240k), \$190k comes from double counting
University accruals and PO's due to some errors in the PO's. We will be
working on reconciling that this month. Overruns in the Silicon Layer 0
(about \$400k) are legitimate and come from overruns in labor. We are
working on estimating the actual amount of labor we need until the end
of the project in order to generate a change request.

Finally the AFEII subproject shows a cost overrun of \$125k for the full
AFEII-t board Production and Testing. This is likely due to advance
ordering of the AFEII-t parts to stuff the boards with, without taking
credit for ordering them and we will also work on getting this
straightened out.
