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

New Tasks and Rods
•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
 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.
• Module production: FNAL & UCSB
 Fast test with ARC/LED
• Simple repairs
 Overnight temp cycling with readout in
“Vienna box”
 Full characterization with ARC/LED

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$

Status of equipment
Quick test hybrids on ARC
Final pinhole test on ARC
Assemble rods from modules
Thermal cycle hybrids
Thermal cycled module
Rod burn-in
Gantry makes modules.
Modules test on ARC
Rods shipped to CERN

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.

• 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.

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

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
