Wednesday Run Plan

  • Tune up beam
  • During this time, as much as possible tune up daq timing
  • Kicker magnet calibration with viewscreen
  • Pair spectrometer checkout/debugging
    This should include setting thresholds, studying rates with air converter, looking at rates with photon hole open
     versus blocked, ...
  • Check detector rates with D2O. See if we can get a good time of flight spectrum.
