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 accelerator issue. ETA was 7-8 pm swing. Beam restored around 9 pm.
- 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=10.37 hr (Upto Friday 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.
- ABU=8.63 hr(Saturday 8 am)
(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. Finished TAC run. Beam restored. But accelerator had problems 1L05,07 NL system at the begining of owl shift. Beam restored at 12:13 pm and production also resumed.
- ABU=14.73 hr (Upto Sunday 8 am), far better
(Monday: upto 8 am)
- Production running from midnight,
- ABU=8.03 hr (Monday upto 4 am)

- 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)
- [8] [9] Pb and Molybdenum foil inserted](Lubomir)
- Doubled the thickness of the Molybdenum (Lubomir)
- [10] [11] 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
- Missing data on channel 23 TPOL(Roman)
- FCAL Base Lockup
- Beam Current over the night (Jesse)
- [12][13]TPOL occupancies not flat before reset of rootspy](Yannik)
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)
