- Check channel efficiencies
- Verify pi0 statistics, estimate amount required
- Parameters
- DAQ thresholds (Nominal: 105, or 5 above pedestal)
- Bias voltage setting (Nominal: 1.2V above breakdown)
- Temperature setting (Chiller = 64 deg F, 18 deg C)
- N_sa and N_sb (N_sa=55 , N_sb=5)
- Effective velocity
- Time offsets
- Time-walk corrections
- LED pulser runs
- Verify fixes to hardware channels
- Check humidity readback/settings
- Create configuration that takes data through the TS for concurrent north and south running
- Automate and enhance scripts to analyze the pulser runs.
- Cosmic-Ray runs
- Settings for cosmic runs: shall we match settings for April running?
