  1. Notes from the previous 24 hours:
  2. CEBAF:
    • No beam due to hallc setup until about 6:30pm. Beam unstable. Lots of trips over night.
    • Access to fix FDC ROC was successful.
    • Accelerator plans to get beam to all 4 halls today.
  1. Action Items:
  2. Issues: Comment box on run start not showing up?
  3. Reports:
  4. Run Plan: Finish FCAL LED runs. Get stable beam. Continue with program. Any changes to installation plans?

  1. Notes from the previous 24 hours:
  2. CEBAF:
    • Access went well, beam pipe was 16.5mm beam right. PSS re-terminations. Solenoid PS fixed *knocking on wood* and was sucessfully ramped to the nominal current of 1350 A
    • Cryo fire?...no, just a bad smoke detector
    • Calibrations ongoing, timings are off. Sean is working on it.
    • MCC focusing today on getting high current to Hall C. Aiming for 10 uA. This could take all day...
  1. Action Items:
  2. Issues: Make e-log button on rootspy not working?
  3. Reports:
  4. Run Plan: DAQ work. Diamond alignment? Continue detector checkouts. What to do overnight?

  1. Notes from the previous 48 hours:
  2. CEBAF:
    • More PSS drops over the weekend. General rhythm: Day shift fixes it by swing. Swing tries to establish beam to halld. Machine has issues over night, which are fixed during day shift
    • Issues with extracting beams to halls A/B/C meant it was all halld over the weekend.
    • Sunday evening saw more CW beam but issues with positioning. Ultimately tagger magnet was increased by 1A and finished fixing the position issues.
    • Overnight saw some straight track running with Hovanes doing the flux optimization today.
    • SL access today, providing time to attempt repairs to the solenoid (may be a comm issue)


  1. Action Items:
  2. Issues: Solenoid PS
  3. Reports:
  4. Run Plan: Hovanes flux optimization/AC calibration. Sergey DAQ work. CDC HV scan? Detector calibrations?

  1. Notes from the previous 24 hours:
  2. CEBAF:
    • 2 PSS drops yesterday. Believed to have been communications related
    • "Knocking on Hall-D tagger's door"
    • Collimator in indeterminate state. Richard reports it isn't moving. Hovannes is in working on it. (fixed by reset)
    • priorities from Accelorator: 1) get in to the tagger. 2) establish CW beam -- they expect all of this today (one shift)
  1. Action Items:
  2. Issues
  3. Reports:

    • 5th pass separator (horizontal) issue. Should be fixed today
    • Currently at 9R. Briefly able to get to Hall-C dumplet
    • Today’s plan: "mini Maintenance day" with NL access
    • Hall-D closed @3pm today
