Commissioning Plan

Before Beam

• Trigger Timing Checkout (placeholder slides)

• HRS Detector Checkout
  • VDC Wire Hits (placeholder slides)
  • TDC distributions of scintillators, VDCs, and GC (placeholder slides)
  • FastBus ADC distributions of scintillators, GC, and calorimeters (placeholder slides)
