2. CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 2 The Plan Scope has increased: Build ~6000 modules (all of the TOB modules) Place them in ~700 Rods Fly them to CERN and install & test them Build the TIB cylinders and ship them to Pisa Help install and commission the tracker Beyond construction project: Help maintain and operate the tracker Analyze data R&D for future tracker upgrades/replacements

11. CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 11 Schedule Issues Schedule slips Hybrids & Frames are delayed FEDs for testing of large quantities of FE hybrids and modules are expected to be ready in Summer of 2002 Optical hybrids for assembly of modules into Rods will be available starting Summer 2002 Other critical items are performing better Gantries PC based test stands Probe stations Sensors

12. CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 12 US Gantry Preparations 1 st Gantry at FNAL Delivery was delayed 2 months. Expect to have it operational this month or next.

13. CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 13 Other US Activities Probe station at KSU is ready to go Waiting for first silicon which will arrive here soon Mock-up frames for training gantries Last minute request to our group to make these We completed 80 frames in early March

14. CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 14 Tracker I&C Tracker Outer Barrel (TOB) ~3.5 Million channels  Run 2 CDF and D0 combined CERN and USA only USA has to contribute heavily Final testing and repair of Rods at CERN Installation of Rods in the TOB support frame Testing of Rods in place System Ops: Software development, determination operational settings, calibration methods, database management, data quality assurance… CDF and D0 Experience A direct scaling implies many tens of physicists required for I&C and M&O. E.g. Continuous monitoring and analysis of data to catch and correct operational problems will require a lot of manpower Mitigating considerations TOB has relatively few module types and only 2 hybrid types. We expect there to be a remote control room and ready access to data in the USA.

15. CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 15 Planning Components Schedules & Updated Milestones Now know the sensor deliveries from tender Other tenders will occur this year for hybrids and frames Update milestones when all vendor schedules are known Plan is to have updated milestones in October 2001

16. CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 16 US Plans Preparations First gantry Complete installation this spring Some Module assembly this summer Study wirebonding with mechanical prototypes Resolve fixturing and module handling issues Prototype working modules by this Fall Install second gantry this Autumn Test stands Obtain a pc-based test station this Summer for testing modules made here. Prepare a preliminary burn-in station Full production Will not start until we see steady parts flow Need to prepare final burn-in and test facility Probable start of ramp-up is Spring/Summer 2002

17. CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 17 Capacity fall-back plan Capacity Issues Run2b Large overlap at SiDet appears unavoidable Contingency production line at UCSB Planning a 3 rd gantry to do assembly, also wirebonding and testing of ~2000 modules at UCSB Additional needs: 1 gantry, 1 high-speed wirebonder Purchase via startup funds and exchanges with CMS Probably no use of contingency required Gain additional experienced manpower 2-3 Faculty 2-3 silicon and 1 electronics engineers Senior researcher

18. CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 18 Summary & Conclusions Scope has increased Some components are delayed New schedule and milestones this October Currently estimate 6-8 month delay for start-up of full production Expect significant overlap with Run 2b 3 rd US gantry production line at UCSB ~30% of modules, relieve strain at SiDet, help make up lost time if necessary No production until component deliveries reach a steady, sustainable rate.

21. CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 21 Schedule at Review Main Production Period: ~ 8 months of explicit float

22. CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 22 Scheduled & Performed Work, Actual Work Costs Track Record Not really meaningful yet Short lever arm and recently revised schedule Increased manpower allocated to I&C CR: +225,038 FY01$

23. CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 23 I&C Manpower Estimates TOB Assembly period: 1/03 – 7/04 Two shifts per day and several parallel efforts Final test/repair of rods Installation/test of rods System software development/test US Contribution at CERN 5 FTE Physicists 1 Technician (Rod repair - disassembly and reassembly) ** In all cases, resources scheduled for scientists correspond to the incremental cost of residence at CERN (dislocation and travel). TOB commissioning: 7/04 – 9/30/05 3 shifts per day and several parallel efforts Debugging/Optimization Online ops, calibration Software development for monitoring data quality and catching problems. Offline analysis of data US contribution at CERN 7 FTE physicists 1 FTE technician
