Tracker Status

September 10, 2004

Tray Assembly

- A Tracker response to the ART report was drafted and submitted to the project office as a plan forward to resumption of tray fabrication.

- GSFC completed etching and priming of at least 100 tiles.

- INFN met with Plyform to start implementation of the recovery plans. Plyform’s response has been very positive thus far.

- Wire and compression pad materials were found for testing of the ART recommendations.

MCMs

- Production and testing is continuing at Teledyne, with 52 in the production line, including 14 in source inspection.

- Burn-in and final testing is progressing at SLAC, with 36 MCMs presently in the thermal chamber.

- Work in progress on several fronts at SLAC to keep materials flowing into the production line.

- Work progressed on how to address the conformal coating workmanship issues, and investigations into the short circuits continued.

Flex Circuit Cables

- More meetings were held on the coupon testing issues.

- Some trial cable installations were carried out in Pisa on a mockup, and some issues with strain relief and tooling were noted and are being addressed.

Misc. SLAC Deliveries to INFN

- The PO for the shipping container is out and work has started at the vendor.

- Epoxy, tape, and 68 bias circuits were shipped to Pisa.

- The first corner brackets that go at the top of the tower for mounting cables were badly manufactured and are non-flight but will be used for a trial assembly. The manufacturing errors are being corrected.

Tower Assembly

- The trial assembly of a tower will start next week, and all tests and measurements should be completed after 2 weeks. Several non-flight trays were reworked, with MCMs installed, so that the resulting tower will be functional and will provide a platform for verification of the functional tests as well as alignment and mechanical tolerance measurements.
