Schedule & Plans Prof. J. Incandela US CMS Tracker Project Leader DOE Visit January 20, 2004

UCSB CMS Group January 20, 2003, J. Incandela 2 Current Status Components Rely on vendors and colleagues Problems (many found by UCSB) led to delays of varying lengths Module breakage in transport → 2 months Hybrid Cable problem → 3 months ST Sensor issues → ? ongoing ST sensors are only remaining serious concern Various processing problems → inconsistent quality Inability to meet delivery schedule Resolving ST sensor issues: Build many modules to undergo substantial testing Work with ST to remedy processing problems Startup production at Hamamatsu

UCSB CMS Group January 20, 2003, J. Incandela 3 US/UCSB planning UCSB’s role Will build 150 modules with ST sensors Two week period starting Jan. 26 Test of sustained peak rates All production steps and all tests This experience will provide some higher statistics test results for helping us understand ST related problems Initiate order at Hamamatsu (HPK) JI will leave for Japan on Jan. 21 st to meet with HPK management and CMS colleagues Determine HPK capability and schedule Initiate manufacture of all CMS sensor masks except W6 Startup W6 production

UCSB CMS Group January 20, 2003, J. Incandela 4 Outlook Components for modules & Rods Sensor problem will be resolved in the next 2 months May be necessary to use substantial ST fraction Likely that at least a third will be HPK Hybrids are flowing at large rates All other module components ok Rod components mostly ok, some have slipped a bit, but less so than module components. Rods not on critical path Production Expect to produce a substantial fraction of modules in FY04 Rod production will likely keep pace Completion by end of FY05 Still looks good but the pressure is rising.

Incandela 7 Conclusion CMS adds depth and continuity to an exciting program UCSB is major contributor We will be well positioned for the most important Physics Babar & CDF record and experience - a good indication of our potential to play a leadership role in the CMS physics program Good opportunity for students Lead role in challenging, but exciting and critically important hardware effort (Construction, I&C, M&O) Many years of hadron collider data analysis experience on CDF Some of the best people around, in both of these areas, are here.
