Past 24 hours

Issues

Plan

Monday, August 29

Past 72 hours

Issues

  • RootSpy not working
  • AC not working at high gain (Nick) [3]
  • CDC, problem HVBs I-1 and 26 (Naomi & Nick)
  • 3 FCAL bases need to be replaced on Wednesday or sooner if opportunistic access is possible (Mark)
  • Target OVC Pressure (Chris) [4][5][6][7]
  • Lost solenoid B-field on Sunday (Tim) [8] (it took most of the day to ramp up) [9]
  • Tagger dump water flow, settings needed to be adjusted to new conditions?

Plan

  • TAGM calibration (Richard)
  • Debug AC (Nick)
  • PS harp scan (Hovanes or shift crew)
  • Empty target run (shift crew)
  • Wednesday might be devoted to RF recovery/beam study, so halls access might be possible this day
