Phase 0: Diagnostics

  1. One Run with Singles & Pairs Triggers
    • trigger file: HPS/Run2016/v0.trg
    • 30 minutes at any fixed current of 25 nA or greater
    • This trigger configuration should give non-zero rates for all triggers:
      • singles-0, singles-1, pairs-0, pairs-1

Phase 1: Preliminary Tuning

  1. Three Singles+Pairs Trigger Runs
    • trigger file: HPS/Run2016/v0.trg
      • Pair-1 is Kyle's tight A' trigger
    • This trigger configuration should give non-zero rates for all triggers:
      • singles-0, singles-1, pairs-0, pairs-1
      • and 1 kHz pulser
    • 10 minutes at each beam current:
      • 25 nA (or lower)
      • 100 nA
      • 200 nA (If dead time is greater than 25%, lower the beam current)
    • Take a snapshot of the trigger scalers at each current

  1. ECal Pedestal Runs
    • About 10 minutes at each beam current:
      • 25 nA (or lower)
      • 100 nA
      • 200 nA
  2. Three 20 kHz Pulser Runs
    • trigger file: HPS/Run2016/pulser20kHz.trg
    • At least 100 Million events (~1 hour) at each beam current:
      • 25 nA (or lower)
      • 100 nA
      • 200 nA

Ideally the pedestal runs above ~50 nA should be done first so that they can be used
to update the pedestals used for the 20 kHz Pulser runs (for 25 nA, the current pedestals
are fine). This requires an ECal expert available, and to then update the trigger files for the subsequent Pulser runs.

If this is not the case, all the Pulser runs can be done first with the preconfigured pedestals.

Phase 2: Final Tuning
