Non-Production Runs and Bad Runs

Pedestal/Calibrations Updates

Issues

  • There were many pedestal and event cut problems. From now on, when an event cut isn't absolutely necessary it should be removed - see japan source code for reference of cuts here
  • The BCM appears to be falling apart. We are fixing it and running slug 12 on BCM DG DS in the meantime.
  • BPM 4ec had intermittant problems (iocse10 has issues) and so we are regressing with 4e again. BPM 11X is ok and stays in regression.


  • Increase in Detector widths and Collimator temperature HALOG COLLIMATOR HALOG
  • Increase in collimator temperature and raising neutron dose HALOG
  • The increase in detector widths started from late Swing Shift HALOG
  • Cavity BPM lock change HALOG

Other Status Updates
