Tuesday, September 16

  1. Last 24 hours:
  2. Report/issue
  3. Run plan
    • Wait for beam delivery. Begin experiment commissioning. Run plan

Friday, September 17

  1. Last 24 hours:
  2. HARP Scan results: https://logbooks.jlab.org/entry/3906296
  3. Report/issue
    • AC cable wired backward? : https://logbooks.jlab.org/entry/3906359
      • Radcon is escorting Nick into the collimator cave for checking
    • Counting house microphone issue:
      • Improved significantly by the new microphone by Matt
      • A longer USB to micro USB cable will further improve the remote shift experience
  4. Run plan
    • Run plan
    • Complete beam configuration (Hovanes) after fixing Active collimator
    • Detector checkout
      • Contact persons: Rachard (): richard.t.jones@uconn.edu, Drew: andrew.p.smith@duke.edu , Sasha: andrew.p.smith@duke.edu, Igal: ijaegle@jlab.org , Tyler: .
    • Low Current 2nA run this afternoon (during Mike's shift)
    • Empty target run again overnight?

Saturday, September 18

  1. Last 24 hours:
    • AC Fixed at 9:30 am
      • Voltage cable was attached but not locked.
    • Hovanes completed the last step of beam check at 2pm
    • 2nA beam + bleedthrough to the Hall since then.
      • slit close, laser off.
      • Hall C at 70uA and constantly changing current between 50-70 uA
  2. Overnight: snake scan.
  3. Present: snake scan ongoing.
  4. Shift Summary:
  5. Issues:
  6. Run plan
    • TAGM checkout to be completed (Richard)
    • Beryllium target installation
      • 6:30am, Beam.
      • 7:00am- 7:30am, radcon survey of beamline target area.
      • 7:30am- 8:00am, Survey & alignment setup
      • 8:00am-8:30am, removing components (Target & start counter)
      • 8:30am, Berylium target installaion by target group (with Imani's presents)
      • Total work duration: 14 hours
      • Currently planned for Monday.
    • A Possibility of maintenance day on Tuesday.
      • Should we shift target installation by 1 day?
      • Injector tune-up to help bleed through.

  1. Weekend operation:
    • Weekend operation:
      • Hall C on: Close slit, turning off laser. Hall C bleedthrough only
      • Hall C off: Open slit, 2nA beam.

    • 1.5 hour stable TAC run (CCAL Only): Run 80693
  2. Issues:
  3. Near future plan:
    • Hall C tune beam for three hours starting at 10 am, TAC run?
    • Beryllium target installation on Tuesday
    • Full target installation schedule
      • 6:30am, Beam off.
      • 7:00am- 7:30am, radcon survey of beamline target area.
      • 7:30am- 8:00am, Survey & alignment setup
      • 8:00am-8:30am, removing components (Target & start counter)
