Minutes of the Tracker Meeting
March 6, 2003
Action Items:
1. Luca will start making evaluation boards.
2. Luca will send information to Robert on
Italian support of the peer review
3. Tom: check on status of the K13d
procurement
4. Tom: start the procurement of the closeout
pieces for the bottom tray at COI
Luca Latronico reported that they had solved
the mini-tower tray noise problems by grounding the honeycomb with long screws
on the service box handles and on the MCM (where they scraped away the
conformal coat to make contact). They
plan to ship the trays to SLAC at the end of the next week. At least one or two Pisa representatives
will travel to SLAC with the panels.
Luca suggested making a kapton foil with the
capacitive load of detector strips to use to test MCMs. He called it an "evaluation
board." It was agreed that they
will make some now at CERN to use with prototype MCMs. The end of it will have a fanout such that
it can be used even on MCMs without pitch adapters.
Luca reported on some of the test
results. One tray was particularly
noisy: Tray 2 with G on back and F2 on front.
Both sides are noisy, although the noise is not randomly distributed. On the front there are 80 noisy strips
spread across >1 ladder. On the back
there are 200 noisy strips, mostly on ladders 2-3.
Luca agreed to supply Robert with info on how
Italy will support the peer review preparations.
Tom reported that Hytec is working on
completing the reduced model. For that
reason they are delaying the final run of the structural model until next
week. He needs to get money to COI, so
that COI will release the test results to us.
Renderings will arrive from Hytec by noon tomorrow for the peer
review. The requition for K13d is in
procurements' hands. Tom will check on
it today. Closeout pieces for the EM
bottom tray will be fabbed at COI. Tom needs to get that procurement started.
