- NSF RSVP Review
2Outline
- For each Level 2 WBS
- Remaining RD tasks
- Additional resources needed, if any, including
what is and what is not included in the pending
RD proposal - Schedule to complete all tasks and baseline the
subsystem - Revised Construction Cost Estimate
- The impact of delaying a start until FY05 or FY06
3Notes
- We have deferred many tasks for lack of funds,
however we need to define the interfaces to the
solenoids now. The following schedule assumes
that additional money is available - Proposed 3.1M RD grant begins on 4/7/03
- 20 supplemental funds on the existing grants are
available on 2/28/03 - Delays in either push the schedule out, i.e.
funded tasks are on the critical path - The pending RD proposal was limited to 3M, not
because we cannot gainfully spend more, but
because we thought it unlikely that we could get
more. We will note for each task what is in the
request and what goes beyond it. - Comments about the MS project file you have on
the CD-ROM - Allows you to investigate directly the impact of
delayed funding - Tasks in it are for the most part NOT
effort-driven, e.g. resources indicate
responsible people, but anticipated fraction of
effort is only included for Engineering and Design
4WBS 1.1 AGS Mods RD Schedule
- We need to study, bunch intensity limits, 8 GeV
bunched beam extraction, and the extent to which
we can tune to reach 10-9 level of extinction. - Estimated 627k cost precluded this effort from
the RD proposal - In addition to the substantial funds, we need for
Mike Brennan to have some time to work on MECO

21Tracker RD Plan
- In the pending proposal - 840k
- Complete assembly of the full-length vane
prototype - Mechanical and electrical tests with prototype
- Revise the BaBar Elefant chip for MECO use a
joint venture between Houston and LBNL - Prototype boards to use the Elefant chip
- Full-time mechanical engineering support
- Design and prototype a low mass manifold
- Osaka development of 3 m seamless straws (more
details next) - Additional resources required for these tasks
None - Additional tasks to baseline
- Pending the decision on the geometry we will
either need to pursue a second full-length vane
prototype or pursue 15 mm thick straws - Additional resources required for these tasks
- 54k
22Seamless Straw RD Plan
- Production
- Length is limited by the size of oven in which
the Polyamide is polymerized - Single straw cost is high due to the number of
production processes - High-Rate Tolerance requires distributing
charge to the cathode faster than the resistive
straw can supply it. - Strategy
- Manufacture the a 3 m oven and study the
mass-production techniques - Find another material such as PEEK Carbon that
can be extruded - Much better for mass-production with lower unit
cost - Straightness might be an issue
- Build and beam test a 2nd generation prototype in
a high-rate environment - PEEKCarbon or much longer PolyamideCarbon
- Tube grounding
- Improved readout electronics

25Calorimeter RD Program For This Year
- Single Channel Tests
- Use chiller (0.01 deg C, 150 watts _at_ -20 deg
C) to continue tests with better temperature
control - Add and study new low noise fast charge
sensitive preamp - Vacuum (10-4 10-6 torr) to investigate
associated special problems - APD voltage (2 kV) control and stability
against breakdown - Heat transfer in vacuum for electronics
cooling and crystal temperature stability - Nine Channel Tests

- Vacuum chamber and chiller will accommodate
8 x 8 crystal array - Add fast trigger sum to shaper circuitry
- Beam tests
- Study again all of above
- Study nuclear counter effect
- Study rate effects to settle on preamp/shaper
parameters - Sixty-four channel system assembly and tests

crystal array including photodetectors, cooling,
calibration, and readout electronics - Note if we go with PbWO4 instead of BGO, the
costs decrease somewhat - An electrical engineer for readout electronics
development and a technician to assist in crystal

38Changes Affecting Construction Costs
- Increased BNL labor rates and overhead adds 1.3M
- Increased material costs by 4 for inflation from
FY02 estimate. - The MIT construction cost estimate is
significantly higher than NHMFLs - Design costs are similar
- Refrigerator cost is simply scaled from 1.5kW to
1.0kW we will have new data on this shortly - Fabrication and installation costs are higher.
These costs are being scrubbed by MIT, a cost
driver is being studied by General Atomics, and
we are getting an independent cost estimate. - Oversight is higher since three FTE for MECO
oversight of the construction vendor are assumed
rather than the two originally budgeted. - Added a full-time QA person to Project Office per
earlier review recommendations

40Implications of Delayed Construction Start
- The short answer is that I have not calculated a
number for this, although it will have to include
at least six months of the following standing
army costs - Project Manager
- Solenoid Subsystem Manager
- Any other hires (UCI, NYU engineers)
- Interim Base Support (?)
- Of course this begs the question, will there be a
collaboration left at that point?
