Commissioning Plan

Before Beam

  • Set Initial Spectrometer Angles
    • LHRS: ??.?? degrees
    • RHRS: ??.?? degrees
  • Set Initial Magnet Settings
    • Decide on scaling function for Q1s (not linear!)
    • LHRS Momentum: ??.?? GeV/c
    • RHRS Momentum: ??.?? GeV/c
  • Software
    • Demonstrate/write-up new Strip Chart procedure
    • Demonstrate working Podd1.6, ROOT6, replay and online plots with cosmics
    • Demonstrate updated spotL/spotR code (take special run with clock trigger and raster on)
    • Demonstrate updated online liveTime calculations with cosmics/clock
