1. PACS IHDR MPE, 12/13 Nov 2003 Overall Schedule1 Otto H. Bauer MPE Garching

2. PACS IHDR MPE, 12/13 Nov 2003 Overall Schedule2 AVM/CQM Schedule Areas of Concern  Test Cryostat: 4K level temperature and hold time problem, still not at MPE  Filters available, but no documentation: critical for PhFPU  Mirrors: gold layer loose in 3 out of 13 lots, Astrium found no real reason  2.5 weeks delay of FPU integration  PhFPU and Ge:Ga detector arrays on critical path  PhFPU STM cryovibration at CSL failed: 2 broken Kevlar wires  separate qualification program for PhFPU STM and modified Cooler STM (Titanium body)  Grating STM cryoqualified, but CQM failed: loose spring washer  several weeks delay  Distribution Boards: several weeks delay due to misunderstanding between Project PA/QA and KT: poor manufact. quality  possibly another 4 to 6 weeks delay Delivery to ESA: mid June 04, AVM WE two weeks earlier
