Hall D counting room white board
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, Early riser and mid-day shift. Started TAC run study by Sasha at about 2 pm. Expected completion: Late swing shift.Before the Vacuum pump alarm(11:30am-1:15 pm), beam was good with less trips.
- ABU=14.73 hr (Upto Sunday 8 am), far better

Reports
- Harp Scan
- 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)
- Vacuum pump alarmplotGoni Vacuum pump alarms (Keith)Vacuum pump alarm areas
Plans
- bleed through measurement sunday, as of 2 pm it is going forward and Sasha and shift crew is working on it. TAC run started. Expected completion: late swing shift, then resume production
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
- 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
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)

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
