List of changes

These lists are giving the run ranges where the FCAL hardware was not changed.

Periods

The periods in BOLD are calibrated i.e. have a pedestal and gain tables. Each period corresponds to constant FCAL and/or experimental conditions.

  • period 0: (empty Be target)
  • period 1: (empty Be target)
  • period 2: 110498-110549 (Be target - B-field ON)
  • Period 3: 110553-110583 (Be target - B-field ON, FCAL HV change)
  • period 4: 110585-110599 (Be target - B-field ramping down)
  • period 5: 110600-110621 (Be target - B-field OFF)
  • period 6: 110637-110640 (He target cooling - B-field ramping up, FCAL HV change)
  • period 7: 110641-110672 (He target w/ B-field)
  • period 8: 110675-110725 (He target w/ B-field/new trigger)
  • period 9: 110738-110755 (Empty He target w/ B-field)
  • period 10: 110771-110795 (He target w/ B-field - start after maintenance day)
  • period 11: 110796-110805 (He target w/ B-field - beam unstable)
  • period 12: 110808-110811 (He target w/ B-field - beam unstable)
  • period 13: 110812-110??? (He target w/ B-field - start after maintenance day)

Bad block map

This map is done for each run number by combining the info collected by analysing the LED and pi0 skims.
