  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?
