ST has not yet been officially qualified to produce sensors!

We find serious quality and/or robustness issues

As a result production schedule is slipping!

Fortunately we have increased our capacity.

Current situationCurrent situation

• US production readiness• Both production lines can produce 15 modules per day.

• UCSB recently completed 75 modules in one week.• FNAL about to perform a similar exercise

• This is almost double our initial expectations and could be exceeded for short periods.

• Components• All components are procured by European groups

• Hybrids now look ok. Deliveries at high rates• Frames, rod frames etc. all coming in ok

• ST sensors are a serious concern• Possible evidence of deterioration over time• Attempting to move production to Hamamatsu Photonics Corp.

• Situation is ‘delicate’ vis-à-vis the ST contract

• Delays…

Project end & Transition to M&OProject end & Transition to M&O

• We assume we will be needed to cover at least half of the effort of installation and commissioning (I&C) of the TOB.

• Installation/testing of rods in wheels (April 04 – ?).• 2-4 FTE Sr. Physicists, 7 Post-docs, students.

• Testing modules on rods before installation.• Limited system tests.

• 1 FTE Engineer (base).• Rod & Module repairs, cooling system, mechanics.

• Laboratory space and equipment for testing and repairs.• For maintenance and operation (M&O) of the TOB we want a

team that could provide continuous support in all 6 areas of operation.

• In late 2005, large M&O support team must be in place.• We estimate 12 physicists at CERN together with

continued engineering and technical support & associated M&S and operating costs for maintaining a small laboratory space for testing and repairs.

M&O for Tracker Outer Barrel*M&O for Tracker Outer Barrel*1. Operation 3-4 phys., 1 tech.

• 24/7 on-call to avoid dead time.• Includes Leadership: to organize

overall effort, make executive decisions for effort allocation and interpretation of diagnostics results.

• Interface with experiment and rest of CMS admin. (1 FTE of overhead).

2. DAQ – 2-3 phys., 0.5-1.0 Eng., 2 tech.• Front end and upper level modules.

• FEDs and EB managers.• Diagnostics, testing,

repairs, re-testing, swapping of critical DAQ modules.

3. Radiation protection and cooling 2-3 phys. 0.5-1.0 engineer, 1-2 tech.• Monitoring, repair.• System issues: cooling tech present

at all times dealing with problems as they arise.

4. Power supplies. 1-2 phys, 1-2 tech.• Startup crucial. Techs needed for

testing all supplies prior to installation, then retest after installation.

• Safety interlock issue. A serious ongoing maintenance issue.

5. Monitoring and calibration databases 1-2 physicists at CERN.

• Need some resident presence for calibrations.

• CDF does this remotely and sees remote calibration control to be a serious problem.

• We expect a much larger population (possibly students) will work remotely.

• Need to catch problems in data and in calibration techniques.

• Significant effort to maintain good channel list.

6. Alignment 1-2 phys., ½ tech.• Laser alignment runs, hardware

maintenance.• Offline alignment and monitoring of

alignment constants.

*Based upon Run 2 Tevatron silicon experience

Response to April ‘03 ReviewResponse to April ‘03 Review

“The manpower and M&O cost estimate for the TOB are internally consistent, but should be reviewed by the collaboration management to see if adequate resources are available within U.S. CMS or the CMS collaboration at large, given the CDF Run II experience.”

Response:

Our main goal is to have at least the minimum required to have a continuous presence in all 6 areas of operation of the microstrip tracker. We do not need to have more than this because all other tracker subsystems will provide manpower and the operation of the tracker as a whole will be shared by everyone, due to the commonality of the electronics from front-end to DAQ.

Note however, we do not want to have less than this since we could not have significant involvement in all of the main areas of operation.

Finally, several new groups have joined and we will encourage them to add some support to our presence at CERN.

Upgrade R&D IssuesUpgrade R&D Issues

• CMS silicon has limited lifetime.• 10 years of operation (we hope).

• Further, possibly higher luminosity running will require more rad-hard silicon than currently exists.

• R&D for current silicon took many years.

• Expect to participate in future efforts at least at the level of prototyping and testing silicon or silicon-alternative designs.

• 60k$ per year M&S (not included in current budgets)

• Now preparing a proposal at this level for FY04

MEG Review at Brookhaven, Feb 5, 2004 : CMS Si Tracker Project: J. Incandela 17

Summary & ConclusionsSummary & Conclusions

• US Groups now responsible for building and testing more than half of the silicon strip tracker

• We are ready for high throughput.

• Most components ok and in high rate production.• ST sensor issue is serious: no clear solution in sight

• We are still planning to complete the project in FY05

• Based on CDF/D0 experience, significant resources will be needed for I&C and M&O.

• We estimate ~12 post-docs plus engineering and technical support to allow US to have significant involvement in all aspects of operations
