Schedule Plans Prof J Incandela US CMS Tracker

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

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 2

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 W 6 • Startup W 6 production UCSB CMS Group January 20, 2003, J. Incandela 3

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 FY 04 • Rod production will likely keep pace • Completion by end of FY 05 • Still looks good but the pressure is rising.

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.
