  Status of ZDO Testbeamtime:

  This morning the last measurement was made with a 10 mu scintillating foil and a reduced ZDO. For the description of the total testexperiment see the ZDO light page.

  Next tasks for the experiments:

  1. Mounting for hodoscopes (will be finished by middle of November)
  2. Missing detectors from Catantia (Giovanni will come to GSI by the end of November)
  3. Test with Neutronsource (last week of November)
  4. Tet of changed photodiodes at Crystals
  5. Test of GSI hodoscope

  Time schedule for some tasks:

  Mounting of the target chamber in Cave B (End of November)
  Check of all hodoscopes (Begin of December)
  TOF Functionality test (until begin of December)
  Vacuum cooling of TOF (Brass bar comes at 11.11.94)
  Telescopes/Mounting (???)

  Miscalleneous:

  Targets for the experiment (25 mg, 50 mg, 100 mg, 500 mg)
  Silicon Strips - 1. Where should the Detectors mounted? 2. Which preamplifiers should be used?
  Start detector - A new chamber is under construction, the FOPI PMs get special flanges with plexiglas windows. One should look for veto detectors outside the Start chamber to shield the hodoscopes against scattered particles from the start detector.

  Next meeting:
