    • Spent all day and into swing on Friday to fix BLM trips. This worked, and the beam was quite stable. RF and BLM trips down
  3. Action Items
  4. Issues
    • DAQ issues: rocCDC2, dropping to 0 rate during running with 450nA beam.
  5. Reports
  6. Run Plan
    • Beam Studies today. We are getting parasitic beam at the moment. Who needs an access? Who wants an access? How long do you need?
    • Likely RF Recovery tomorrow

  1. Notes from the past 24 hours:
    • Beam back at 11:30 am, Sasha finished L1 trigger studies by 2:00 pm
    • MCC suggests they recalibrate iIon chamber to reduce trip rates. Previously, it was only calibrated up to 80 nA.
    • Sergey performed high rate DAQ tests with current up to 900 nA
    • David has new online monitoring site up
  2. CEBAF
    • Almost 20 BLM trips/hour through yesterday and into the early morning. Hall C went down around 4 am and BLM trips were significantly reduced. They think there is something wrong with the beam that is being injected into the accelerator.
    • Will do a retune of the accelerator around 10am today. Should take 1-2 hours.
  3. Action Items
  4. Issues
  5. Reports
  6. Run Plan

  1. Notes from the past 24 hours:
    • Beam issues most of swing (7hrs to complete amorphous run) and owl shift (~1hr of beam in total).
  2. CEBAF
    • 5th pass separator failed during swing shift and remained problematic into the beginning of owl. Beam back at 3:20am.
    • PSS drop in the machine at 3:30 am. No beam until 6am.
  3. Action Items
  4. Issues
  5. Reports
  6. Run Plan
    • Need to schedule a TAC run
      • Can we do this opportunistically?
      • Use bleedthrough current?
      • Hall C plans to switch experiments on approximately the 22nd. This is around the time of accelerator maintenance, so they may plan to switch experiments then.
    • Hurricane Michael arriving this evening. Do we need to take any precautions?
    • Week 4 Week 5
      • Beam Studies Monday
      • RF Recovery Tuesday
