2. US CMS Silicon Tracker Project – Breakout session Overview - DOE/NSF Review Brookhaven - May 20, 2003 - Incandela 2 Executive summary Many significant achievements this past year  Technical concerns have been alleviated and parts are flowing Regina Demina follows this closely for the US and will present a detailed summary next. We have taken a number of steps to help this effort: Hybrids work at UCSB & Sensor QA at Rochester  Both US production lines are complete & well-exercised ! Results are excellent: More details below.  US Module testing is the template for the tracker project Tony Affolder has been a great new addition to the testing effort and has brought much CDF experience. He will present the status of this work. Remaining problems/concerns: None are severe.  Hybrids are ok now. Production this summer will be a test of capacity.  Test equipment and software We are ok for ramp up now but need to complete our full suite in order to do complete testing and large volume testing  Manpower FNAL: was a big concern – recent efforts have begun to pay off UCSB: Fine for now and has a good pool of students to draw on  Technical issues Recently have seen some damage in transport – under investigation now

4. US CMS Silicon Tracker Project – Breakout session Overview - DOE/NSF Review Brookhaven - May 20, 2003 - Incandela 4 Overview FNAL and UCSB will have equal capabilities and capacities  FNAL production line Gantry operational – made ~20 operational TOB modules. 2 of 4 DAQ and 2 of 4 ARCS  UCSB Production line Gantry operational –made ~10 operational TOB modules 1 of 3 DAQ and 3 of 5 ARCS  UCR module diagnostics and repair 0 of 1 DAQ and 0 of 1 ARC TOB Module Summary Table

5. US CMS Silicon Tracker Project – Breakout session Overview - DOE/NSF Review Brookhaven - May 20, 2003 - Incandela 5 New Tasks and Rods Hybrids  Final assembly at CERN a bottleneck. US Helping in two ways: G. Pasztor (UCR) at CERN We’ll now do the final wirebonding and thermal cycle tests at UCSB  Wirebonded and Tested: UCSB Quick Test then Wirebond pa’s Thermal cycle with continuous ARC test and pitch adapter pulsing Adds 3.3 M bond wires !  Ship half to FNAL Module production: FNAL & UCSB  Fast test with ARC/LED Simple repairs  Overnight temp cycling with readout in “Vienna box”  Full characterization with ARC/LED Rods  Have infrastructure being prepared and space available.  Have identified personnel UCSB: Dean White with Sean Stromberg and others FNAL: Rochester physicists and FNAL techs.  CERN tooling is en route Will likely need modification after we gain some experience.

12. US CMS Silicon Tracker Project – Breakout session Overview - DOE/NSF Review Brookhaven - May 20, 2003 - Incandela 12 Wirebonding FNAL ok now with new bonder…  Saved ~120k$ UCSB has 2x as many bonds  Wise to find a used K&S 8060 Smaller work table than 8090: Adequate for hybrids but not ideal for modules Much more common than 8090 and frequently seen on used market for < 100k$

13. US CMS Silicon Tracker Project – Breakout session Overview - DOE/NSF Review Brookhaven - May 20, 2003 - Incandela 13 Status of equipment Quick test hybrids on ARCGantry makes modules. Modules test on ARC Assemble rods from modules Rod burn-in Rods shipped to CERN Thermal cycled module Wire bond Final pinhole test on ARC Wire bond Thermal cycle hybrids

14. US CMS Silicon Tracker Project – Breakout session Overview - DOE/NSF Review Brookhaven - May 20, 2003 - Incandela 14 Fragile components Transportation a serious business Careful visual inspection of components necessary Recent experience has been awful  6 US modules made at both locations in 4 shipments by 3 transportation methods were received by CERN with similar severe damage!  Change to more flexible glue ? – under investigation – not expected to be a long-term problem but likely to be a long-term worry.

15. US CMS Silicon Tracker Project – Breakout session Overview - DOE/NSF Review Brookhaven - May 20, 2003 - Incandela 15 Tracker: Transition to M&O Abrupt shift to M&O in FY06 reflects the fact that we anticipated and included adequate resources for pre-ops in original project file. See my talk later for basis of resource estimates.

16. US CMS Silicon Tracker Project – Breakout session Overview - DOE/NSF Review Brookhaven - May 20, 2003 - Incandela 16 Tracker Milestones (v33) V33: TOB complete in April ‘05. We currently schedule our completion by April 2005  This is about 3 months looser than CERN schedule  High probability of completion by Sep. 30, 2005 – additional 6 mo.contingency

17. US CMS Silicon Tracker Project – Breakout session Overview - DOE/NSF Review Brookhaven - May 20, 2003 - Incandela 17 Tracker Project Resources Roughly on track but peak will likely shift a bit UCSB currently pat FNAL in the process of gaining a few people as needed

18. US CMS Silicon Tracker Project – Breakout session Overview - DOE/NSF Review Brookhaven - May 20, 2003 - Incandela 18 Tracker FY03 Planning 2 Rochester technicians involved in FNAL production lines Mostly production labor No contingency used (yet)

19. US CMS Silicon Tracker Project – Breakout session Overview - DOE/NSF Review Brookhaven - May 20, 2003 - Incandela 19 Summary We feel that actual mechanical fabrication infrastructure – both equipment and manpower- is in very good shape in the US  Database still needs to be finalized but is not critical  Some new problems with glues expected to be resolved quickly The main issues now for the US groups are:  Testing: test equipment and software This is probably the area of greatest activity this past year US playing very big role in establishing protocols Currently limits are overall throughput  Components schedules Vast improvement and resolution of many issues over past year We have nearly continuous information flow All the right steps have been taken in Europe and US Remains now to see how the big orders work out. Agenda for remaining talks  Have therefore scheduled talks in this breakout session that only cover these two main points regarding production  Also include a talk on M&O
