Commissioning studies (at 250 V/cm unless specified)

  • General debugging and problem solving
  • Measure noise levels with HV off
  • Test pedestal determination algorithm with HV off and HV on
  • Adjust wire plane bias voltages to achieve transparency - must be done at each drift field setting
  • Scan FE-amplifier settings (gain and shaping time) and measure pulse height and width - event display sufficient
  • Adjust timing offsets to align counter data with PD data with TPC data (APA crossing tracks)
  • Zero suppression tuning
  • Determine PD operating parameters (scan voltage and readout window length)
  • Preliminary gap deflector studies
Revisit for every drift field setting
  • transparency
  • Zero suppression tuning
  • PD operating parameters?
