Contents
Friday March 10
Past 24 hours
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=5.48 hr(till 12 am), ~2 bn production triggers till 5 am, smooth running over the night
Shift Reports
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)
