Past 72 hours

Friday(Saturday) March 10(11)

  • Production whenever beam available on Friday mid-day shift, then at 2:51 pm beam down due to multiple reasons on accelerator. ETA 7-8 pm swing.
  • Harp Scan[Friday swing]
  • Opportunistic Access(Friday): Karthik, Zisis, Stejphan: (EIC) mini BCAL prototype test
  • Hovanes:TPOL crate powercycled: looks resolved after increase of delay by 60s
  • ABU's from scheduled 72 hours

Shift Reports

  • Day shift March 10[ Day shift March 11][Day shift March 12]
  • [Swing Shift March 10][Day Shift March 11][Day Shift March 12]
  • [Owl Shift March 10] [Owl Shift March 11][Owl Shift March 12]
  • [Early Riser Shift March 10] [Early Riser Shift March 11][Early Riser Shift March 12]

Reports

Issues

TPOL alarms after Powercycle of crate

Plans

  • bleed through measurement sunday? or TAC run when the opportunity comes.

Regular Production Cycle

  • Production (300 nA, 2h runs) with cycle:
    • 2 runs PARA (0/90)
    • 2 runs PERP (0/90)
    • 2 runs PARA (45/135)
    • 2 runs PERP (45/135)
    • 1 run AMO (use it to rejuvenate AMO reference in CBREM EPICS GUI)



Friday March 10

Past 24 hours

  • Production continued
  • Four hall operation until ~11 pm, then HallC down until the morning. A,B and D operational overnight.
  • Beam was trippy during the day but got better over the swing shift through owl shift.
  • ABU=10.37 hr(midnight), ~4bn triggers

Shift Reports

Reports

Issues

  • TPOL alarms continued
  • DAQ live time 0%, restart did not solve, Surgey had to reset gluon01 crate: solved
  • DAQ issue early riser this morning: ROCFCAL error,DAQ reset (solved)
  • Active collimator bias voltage:[1] alarms to EPICS (Lubomir and Hovanes to communicate for TPOL card, one is in use. We should have one more somewhere)

Plans

  • Opportunistic Access by Zisis/Karthik for mini BCAL prototype
  • TAC run (next week? or 3/10: HallC down for the night and probably for entire morning)
  • Energy measurement at HallC
  • Bleedthrough measurement at HallD
  • if HallC run low current or down for 2 hours at least, Sasha will do some work on TAC run.
  • 3/10 HallC will have some down time at least some part of morning confirmed from HallC RC(Joerg), can we do some tests during HallC downtime?
  • Sasha Positive for the morning(3/10) based on HallC condition till that time.

Regular Production Cycle

  • Production (300 nA, 2h runs) with cycle:
    • 2 runs PARA (0/90)
    • 2 runs PERP (0/90)
    • 2 runs PARA (45/135)
    • 2 runs PERP (45/135)
    • 1 run AMO (use it to rejuvenate AMO reference in CBREM EPICS GUI)

Thursday March 9

Past 24 hours

  • Work on Injector(early day shift): completed, beam restored.
  • HI test(900nA) Pb and Mo foils, HI study completed at the end of day shift and nominal production conditions restored including AC gain 10^-8
  • Production resumed at swing shift with AMO radiator configuration
  • Rate Scan study by Sasha: Swing shift, raw and production mode at different currents:300nA, 350nA and 400nA
  • Production resumed with 0/90 PARA after Sasha's rate scan completion
  • Beam off due to 1L09 tripping high voltage(~1.5hr)
  • Beam (trippy) early owl shift, then better beam, then beam current was fluctuating and was under 300 nA
  • ABU=11.28 hr(till 8 am 3/9), ~2 bn production triggers till 5 am 3/9, smooth running over the night

Shift Reports

Reports

Issues

  • TPOL alarms
  • DAQ issue this morning: live time dropped to 0%, restarting solved the issue

Plans

  • TAC run whenever opportunity comes( HallC run at small current or down)

Regular Production Cycle

  • Production (300 nA, 2h runs) with cycle:
    • 2 runs PARA (0/90)
    • 2 runs PERP (0/90)
    • 2 runs PARA (45/135)
    • 2 runs PERP (45/135)
    • 1 run AMO (use it to rejuvenate AMO reference in CBREM EPICS GUI)
