The PlanThe 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

Schedule IssuesSchedule 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
CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 12
US Gantry PreparationsUS Gantry Preparations
1st Gantry at FNAL• Delivery was
delayed 2 months.
• Expect to have it operational this month or next.
CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 13
Other US ActivitiesOther 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

Tracker I&CTracker 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.

PlanningPlanning
•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
CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 16
US PlansUS 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

Capacity fall-back planCapacity fall-back plan
Capacity Issues• Run2b
• Large overlap at SiDet appears unavoidable
• Contingency production line at UCSB• Planning a 3rd 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
CMS Si Tracker Project - US CMS Meeting at Riverside – May 19, 2001 18
Summary & ConclusionsSummary & 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
• 3rd 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.
