1. Past 24 hours:
   • Short access after meeting
   1. • Beni/Tim: adjust rotometer flow to 1 L/hr
      • Sergey and Hovanes: DAQ
      • logbook entry Chris, Colin, Nick, Sasha: FCAL VME crate 11 power supply/ fan issue
   • gluon01 is back with a new kernel and graphics driver
   • Production running
2. Issues
   • Problematic FCAL channels near beamline
   1. • One base lost connection and was recovered by power cycling the power supply. This happens 1-2 times per week. Right now I (Colin) am the only one capable of doing this. Need to train more people how to spot and fix these errors. It is a relatively simple process, but one that should not be left to the shift crew.
      • One base lost HV near beam line. Access needed? Need to discuss offline how to best HV failures near beamline.
3. Reports
   • FCAL scalers since LHe target switchover (follow up from disconnected crates)
4. Today:
   • Production: 200nA, Al 10^-4
5. Run Plan
   • Production running
   • TAC run
