FGT Commissioning Tasks / Cu-Au running

Updated on Fri, 2012-05-11 07:21. Originally created by surrow on 2012-05-11 07:14.

Trigger / Configuration:

  • Low-multiplicity trigger 
  • A special configuration a al 'fgt_setup' will be prepared
  • Data taking will be handed over to FGT crew (Bernd & Gerrit) taking runs under different parameter settings
  • Need data available for fast offline processing

Tasks:  

  • HV: 
    • Data set 1: 
      • 90/10 : Perform scan for fixed HV of all 14 quarter sections (2700V - 3700V) with current latency
      • Adjust HV to equalize response based on total cluster charge
      • Choose mean HV such that efficiency is 'high' based on previous studies (Compare HV voltage values to set 14)
    • Data set 2: 
      • Take high statistics run with new HV setting 
    • Data set 3:
      • Take high statistics run with adjusted HV setting using track reconstruction
  • Timing:
    • Data set 4: 
      • Perform timing scan with adjusted HV setting 
  • Efficiency scan:
    • Data set 5:
      • Perform fine HV scan (50V steps) for disk 3 while keep HV for disks 1, 2, 4, 5 and 6 at adjusted values
      • Prepate efficiency vs. HV
  • Gas: 
    • Change gas to 70/30 and 80/20 and repeat above steps (2 X three data sets plus efficiency scan)
