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 mid-owl shift.
• ABU=10.37 hr

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 Day shift
• FCAL Base Lock up alarms:swing shiftFCAL Base lock up (42,7) and (45,13)(25,27):owl shift

Issues

• TPOL alarms continued
• DAQ live time 0%, restart did not solve, Surgey had to reset gluon01 crate: solved(shift crew will be watchful if it reappears)
• Active collimator: 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.
• 03/10 HallC will have some down time at least some part of morning confirmed from HallC RC(Joerg), can we do some tests on this down time?
• Sasha Positive for the morning 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)
• [1] [2] Pb and Molybdenum foil inserted](Lubomir)
• Doubled the thickness of the Molybdenum (Lubomir)
• [3] [4] 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)
• [5][6]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)
