Tracker Status

June 11, 2004

Tracker-Grid Interface

- Flight cones, studs, shims, and hex bushings are on order from AMT.

- Nitronic-60 nuts are on order from Diamond Tool and Die.

- Work is in progress on the remaining GSE tools for installation.

Bottom/Top Tray Panels

- The assembly drawings are completed and released.

- The new EM bottom tray was assembled this week and is being

dimensionally checked by CMM today.

- The static test will be executed on the EM bottom tray this weekend.

- Top tray closeouts are ready to be machined.

- The Tower-A bottom tray will be assembled next week.

Mid Tray Panels

- 17 trays have been completed through ESPI testing, and

7 trays are completed up through vibration testing.

MCMs

- 85 MCMs were completed at Teledyne as of a week ago.

- We expect that 99 will have been completed by COB today.

- Steps are being taken to get the rate back up to 5/day next week.

- An MRB is being held on Monday to decide whether to rework the

MCMs with 75-ohm termination resistors on the clock busses.

Tray Assembly (MCM and ladder integration)

- Assembly drawings are ready to go out for sign-off.

- The procedure document is out for review.

- The outcome of work at G&A this week is that the MCM mounting tooling

needs another tweak. Tray assembly should start next week, and we

will investigate with G&A how to make up the schedule slip.

Sidewalls

- Prepreg is at Plyform.

- There have been some problems with procuring the desired aluminum foil,

so we are looking at a possible change in spec to use a foil quickly

available in Italy.

- The release of the assembly specification document is still in iterations.

Flex-Circuit Cables

- The flight cables are on order, with 2 sets due July 8.

Tower Assembly and Alignment

- Work is moving forward to develop and test the alignment procedure using

at SLAC the I&T mockup tower.

- After the EM vibration test, that tower (with its flight-like bottom

tray) will be used to test the procedures in Pisa.

Vibration Test

- The vibration fixture should be done in the SLAC shop today.

- The studs were coated and Monday/Tuesday will be fitted with

locking devices.

- Plans are in work to hand carry these items to Pisa mid next week.

- TRR end of next week.

- We are shooting to start the vibe test June 21.
