Monday March 13(Past 72 hours)

Friday Through Monday March (10-13)

(Friday)

• 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: alarm exists but self disappears quickly after increase of delay by 60s
• ABU=8.63 hr (Upto Saturday 8 am)

(Saturday)

• Production continues, Issue on 1LO4 HV drop(NL) : cost ~2 hours of downtime, trippy beam
• Beam back: day shift crew continued production followed by swing(trip rate is still high), towards the mid-swing shift: trip rate low, better beam delivery.

(Sunday)

• Production continues throughout the owl shift, and beam was relatively more smooth than yesterday.
• ABU=14.73 hr (Upto Sunday 8 am), far better

Shift Reports

• Day Shift March 10Day Shift March 11[Day Shift March 12]
• Swing Shift March 10Swing Shift March 11[Swing Shift March 12]
• Owl Shift March 10/11 Owl Shift March 11/12[Owl Shift March 13]
• Early Riser Shift March 11 Early Riser Shift March 12[Early Riser Shift March 13]

Reports

• Harp Scan Sasha
• PS FADC Scalar Readouts(Left/Right arm) dead channels(Lydia)[1](Left arm) [2](Right Arm) [3]dead and non dead channels
• Switch COBREM Template to new TAGM configuration(Hovanes)

Issues

• TPOL alarms after Powercycle of crate, alarm still exists but less frequent
• FDC HV Channel 2 C1 trips every couple of minutes (Amy)
• Lowered the FDC HV channel 2 C1 2150V to 2125V (Lubomir)
• FCAL base lock up (41:48) (11,49), (28,50) (41,39)(18,32) manual reset(Amy)

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

• Day Shift Summary
• Swing Shift Summary
• Owl Shift Summary
• Early Riser Shift Summary

Reports

• Main Trigger Scalar frozen restarted (Alexandre D.)
• FCAL Base (22,55) lock up and reset Alan G.
• FCAL Base Lock up alarms:SashaFCAL Base lock up (42,7) and (45,13)(25,27), (-5,-3): Rebecca B.
• Off node in addition to base lock: required to reset [Jesse H.]
• Strip charts for DAQ status, current, PS/PSC rates etc..

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:[4] 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

• Early Riser Shift Summary
• Day Shift Summary
• Swing Shift Summary
• Owl Shift Summary

Reports

• High intensity test with Pb and Mo foils(Justin)
• [5] [6] Pb and Molybdenum foil inserted](Lubomir)
• Doubled the thickness of the Molybdenum (Lubomir)
• [7] [8] CDC currents with W and W+Pb foils (Naomi)
• CDC currents with W and Mo foils (Naomi)
• CDC AI on 16:25 3/8 swing (Naomi)
• Beam halo alarms
