Revision as of 18:38, 7 September 2011
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.
