2. PACS SVR-II 18 January 2007 FM ILT overview2 The PACS FM ILT started with warm short functional tests (SFT Warm) on October 12-18 Cold tests were executed between October 31 and December 22, based on the test plan (B) that was introduced by U. Klaas in the previous presentation Phase I of the PACS FM ILT ended on January 4 with another SFT Warm

3. PACS SVR-II 18 January 2007 FM ILT overview3 Progress was very good! All planned tests were executed (sometimes ahead of schedule), except one test block (photometer set- ups III), which was replaced by further tests of the spectrometer (including red!) (Preliminary) analysis reports exist for most of the tests (see below and the following presentations, see also the SVR-II web page), but naturally some test data carry further information that still needs to be extracted.

4. PACS SVR-II 18 January 2007 FM ILT overview4 most of the mechanisms (grating, filter wheels, calibration sources, hetaers, flashers, OGSE mechanisms, xy-stage, etc.) are functional and perform as requested the bolometer and spectrometer detectors seem to be in spec (NEP) PSFs and spectral resolution seem to be in spec autonomous operations (long tests over night) were possible the Lens laser setup worked extremely well stable DECMEC (but QM) data analysis, mostly within PCSS, much more routine-like (and faster) than at CQM ILT

5. PACS SVR-II 18 January 2007 FM ILT overview5 the chopper is non-conformant the spectrometer slicer unit is non-conformant no DECMEC FM yet

6. PACS SVR-II 18 January 2007 FM ILT overview6 Original Plan was to warm up at the end of Phase I in order to replace the DECMEC QM with the DECMEC FM (see previous talk by U. Klaas) However, the chopper non-conformance required a full warm up and opening of the cryostat to inspect and possibly exchange the chopper The chopper performance was good enough to continue the planned tests of phase I without information loss In order to characterize the spectrometer as much as possible to detect potential major problems before opening the cryostat we decided to expand the spetrometer test program in phase I For tests of the red spectrometer we needed to connect the red Ge:Ga array to the blue DECMEC (switching cable connections at 40K).
