Minutes of the forward endcap EMC eZuce SRN meeting, 14th of August 2017, 14:00-14:30

  • Werner mentioned the tolerance of the gain determining capcitors in all three gain versions (0.5, 0.6, and 0.7 pF nominal capcitance) to be +/- 0.05 pF.
  • However, from Maltes measurements obviously the medium gain range with the 0.6 pF capcitors shows clearly larger variation than +/- 10% and larger ones than the other gain versions
  • We therefore need the individual preamp gains for matching, either from the Basel measurements (availability, precision?) or from new measurements to be done by ourselves

Annealing LEDs in APD subunits:

  • Tests with different cabling arrangements done and quite promising
  • Detailed results will be given in two weeks


  • Test setup for incoming SADC boards almost finished
  • Problems with the power supply solved
  • It seems that data transmission may be movable from SADC board to backplane (interesting for barrel and backward endcap):
    • One transceiver for more than one SADC board
    • Several SADC boards to be connected in series
    • Saving of number of data concentrators
  • Further work on backplane design ongoing
