Friday March 10

Past 24 hours

DAQ issue with live time drop to 0%, Surgey reset gluon01 crate to resolve the issue.

Shift Reports

• [Early Riser]
• Day Shift Summary
• [Swing]
• [Owl}

Issues

• TPOL alarms
• 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(1/2))

Plans

• Opportunistic Access by Zisis/Karthik for mini BCAL prototype
• TAC run (next week?): 1) energy measurement at HallC 2) Bleedthrough measurement at HallD and if HallC run low current or down 2 hours at least, Ssasha will do TAC run, Hall C run co-ordinator will look and communicate if that is the case.

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 12 am), ~2 bn production triggers till 5 am, 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)
