Presentation Transcript

  1. Instrument models and test campaigns Overview of tests and test campaigns:CQM-ILT, CQM-IMT , FM 1, and FM 2 SVR 20 – 21 April 2006, Groningen W. Luinge

  2. Introduction • DM-ILT program finished (band 1, 5, partial warm units) • Validation of test equipment & EGSE “finished” • Testing as much as possible via CUS scripts, configuration files, MIB • Analysis of results partly via database/IA

  3. CQM (EQM)-ILT • Early October 2004 – 12 December 2004 • Configuration: • FP Band 3 (H/V) • WBS one polarization • HRS one polarization • ICU no redundancy (AVM) • OBS … - 2.22 • LO (band 3A/B, few frequencies); LSU simulator • Goal: Preparation for IMT (no external stimulator) • Tests: Functional test (no tuning); stability (; standing waves) • Conclusions on ripples, diplexer behavior (together with 2 side bands and standing waves), calibration source, noise temperature, LO reproducibility, chopper & OBS (non-)behavior • Start of understanding HIFI

  4. CQM-IMT • At ‘satellite’ level • In old ISO cryostat, with PACS and SPIRE • Control via CCS, Herschel PDU simulator • With LSU simulator • ICU CFM 2 for EMC test • October (IMT), November/December 2005(EMC, thermal behavior) • Results: see presentation of Nick Whyborn • Also results regarding integration procedures, use of IEGSE, etc

  5. FM 1 • FM1 refers to FPU tests with MSA’s 1, 2, 3, 5 • November/December 2005 • To test FPU performance (presentation of P. Dieleman) • To measure the beams (presentation of M. Jochemsen) • Feedback (new grids in band 1, polarization correction in band 5, chopper magnets): implemented • In this period also the start of the WBS integration with ICU/EGSE/HCSS • inrush current reduction, OBSW debugging, new HCSS release, new OBSW version, temperature stability of environment, … : not yet finished completely --------------------- • After FM1: completion of the FPU and modifications

  6. FM 2 • Now going on • FPU performance of all bands and beam measurements • Check improvements • Continuation of WBS integration • ICU (AVM2, OBS 3.5), GSE and tested with scripts: KOSMA performance not fully reproduced • Start of ICU - HRS integration • HRS integrated with ICU, WBS (AVM2, OBS 3.5), GSE and tested with scripts: CESR performance reproduced (TBC) • Test equipment is being upgraded (// set up, re-imager controlled by scripts, etc.) • Next: Integration with ICU ..; preparation for cold vibration
