Status of experiments

see hardcopies --- annex 13

  1. GOLF (A.Gabriel)
    no change in performance specifications; all subsystems have been shown to be functional; QM foot failure (needs more strengthening); power supply unit problems (filtering connectors not reliable) delivery delay of 6 weeks (15.8.30.9.); schedule delay under evaluation.
  2. VIRGO (C.Fröhlich)
    same power supply unit problems as GOLF (CRISA); delivery date of FM 29 Nov. -- 3 Dec. 93; FS ready 1 March 94.
  3. SOI/MDI (A.Title)
    field tests presented; no schedule problems at the moment; delivery date 11 Nov. 93.
  4. SUMER (K.Wilhelm)
    SM+EM delivered; new project manager: E.Keppler (MPAe); the problem are the MAMA detectors; solved problems: vibration, alignment, EMC; other problem: mirror performance (2'' instead of 1'' resolution only), although the mirror was shaped to 0.6'' (this means that the mirror definitely has changed); A.Title commented that it is well known that SiC mirrors are not stable.
  5. CDS (E.Sawyer)
    new CDS blue book issued (vers.5); FM hardware manufacture 90% complete; telescope manufacture complete, assembly started; spectra presented; areas of concern: schedule (adequate time for test and calibration?) + availability of instrument for re-calibration after AIV.
  6. EIT (J.-P.Delaboudiniere)
    still problems with the mirror mounting; only 75% of the filters survive tests; never seen a completely assembled instrument(!); include shield to bring CCD temperature close to -80C; add extra filter to reach a stray light level ; problems with the schedule (no time for calibration!) 1 month delay.
  7. UVCS (K.Kohl)
    The problem are the MAMA detectors; no detectors available yet(!); very severe schedule problems.
  8. LASCO (D.Michels)
    no major concerns, only some minor motor anomalies; straylight level of C1 two orders of magnitude better then specified; no descoping of science objectives; well in schedule, but no contingency; delivery date: end of November 93.
  9. SWAN (J.-L.Bertaux)
    High voltage power supply broke again during vibration tests; mirror head mechanism stuck again in cold vacuum ( redesign necessary for HVPS, ball-bearings and head); it is planned to order new 2-point ball-bearings; severe schedule problems.
  10. CELIAS (A.Bürgi)
    new CAMEX production necessary for STOF ( delay of 3 months); sink temperature of SSD radiator still too high; delivery dates: mid of November for CTOF, MTOF and DPU; Januar 94 for STOF; FM2 October 94; swap of detectors FM1FM2 8 months before launch.
  11. COSTEP (H.Kunow)
    problems with the Si(Li) detectors from LBL; delivery date: 15 December 1993.
  12. ERNE (J.Torsti)
    well in schedule, no major concerns; ESU integration starts 30 July; most serious problem at the moment is a software problem at high particle fluxes; delivery date: 11 Nov. 93; FS: May 94.
