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.
