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

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

C3.6Wavelength-calibration using TUFIR replaced by vapour absorption cell C3.7Instrumental profile (grating) measured with TUFIR replaced (however, some initial profile information from absorption line measurements are planned. C3.8Ghosts (search for spectral ghosts) TUFIR only, maybe Ge laser? (C3.9)Stray light (ghosts) with Ge laser? C3.10Detector time response, stability (C3.11) Definition of PACS pass bands with TUFIR (not possible with Ge laser) (C3.12) AOT try out
