  • Design of all assembly devices are ready and

all parts were ordered except:

  • Lugs fitting for transportation device
  • Intermediate plates for turning device
  • They were discussed last week,

drawings will be created soon.

  • Delivery of the crane delayed to cw 50 due to

delivery difficulties. Slice Assembly Workspace & Tools

PSL APD radiation Setup @ Giessen -status last cm-

16

  • Bochum HV control Software EPICS was installed last week by Tobias

Triffterer.

  • Previous Software causes several problems, for example:
  • USB-CAN converter produced a lot of error messages.
  • Channels stopped randomly voltage ramp up
  • Several Software crashes
  • With the new Software and Andrea it was figured out:
  • Some channels had (have) a short circuit
  • Some channels had (have) a loose contact
  • Some channels were (are) wrong wired.
  • The Problems will be fixed together with Andrea in the next few

days.

PSL APD radiation Setup @ Giessen –present procedure-

17

  • Exact 20°C
  • Before irradiation:
  • electric contact checked

individual

  • Dark current measurement
  • Irradiate with 30 Gy and

individual bias for gain 100.

  • After irradiation:
  • Dark current measurement
  • Shipping to PSL

Conclusion / Summary

  • Module assembly:
  • 2/3 of all modules already assembled
  • APD throughput delayed the module assembly

schedule.

  • Still 500 APDs needed.
  • Slice assembly:
  • Workspace and Tools will be ready for slice

assembly before Christmas

  • Fiber coupling will be tested soon
  • Delivery date of needed ASICs and flex PCBs

so far unknown

  • Cooling concept has to be developed
