HV trip recovery

TPC

  • For the TPC, the following variables should be checked:
    • Low voltages
    • Wire biases
  • If the low voltage has tripped, the ASICs on that FT will need to be reconfigured
  • If the wire bias has tripped, it needs to be ramped back up and current draws monitored

PMT

  • For the PMT system, the following must be checked:
    • Rate (in each PMT), correcting for the fact that the HV is off
    • Single PE response
    • Pulse spectrum
