• Topics:

  TOF:

  HV test is possible as soon as Esone server is running in normal mode. The laser system is adjusted. The motor for the second wedge is unplugged so that only the first wedge will be used.

  GSI:

  Cabling is finished. During the testing problems with two silicons arose. In one the noise in one quadrant increased when the bias was swithced on. In the second silicon a signal in one quadrant was missing, but the resistance was ok. Some Temperature devices have to be installed.

  Catania:

  All cables exept the power supply in the chamber are connected. Only two preamplifier boxes are mounted in the chamber. There will be 16 spare channels in the box for the silicon strips.

  ZDO:

  Cables inside the chamber are mounted. The temperature measurement has to be brought in.

  MSU:

  16 detectors are mounted. We are not sure about the vacuum tightness of the flanges.

  Start:

  The Start detector box should be mounted before the vacuum test.

  Telescopes / Si-strips:

  The mounting is inside the chamber. For the system the 4-channel power supplies will be used.

  Electronics:

  The electronics (logic, stretchers ...) will be installed by the Italians, who are at GSI this week.
