Friday, February 2
- Notes from the previous 24 hours:
- Harp scans around 2 pm found the beam was significantly over-focused in y. Around the same time MCC decided to retune the beam.
- After beam tuning in the afternoon, harp scans around 8 pm showed convergence at the collimator is better
- 12.6 hours of CW beam. ABU: 10.9 hrs (3.2+1.7+6.0), BANU: 1.7 hrs (0.3+0.7+0.7), BNA: 11.3 hrs (4.5+5.6+1.2)
- Spreadsheet: number of triggers.
- Low level monitoring
- Issues:
- CDC-FDC Pressure dip and Beni's followup -> opportunistic access?
- 5C11B Y position wandering
- Coherent edge fitting: New amorphous reference to be taken this morning. ROOTSpy should use 41180 from last night.
- ROOTSpy Modification
- New "5 DC" DAQ default configuration
- Today's run plan Google Calendar:
- Production running
- 10 am: Min-bias trigger setup (Sasha)
- 11:30 am: High intensity test (Sergey)
- Reports:
- Standing issues:
- Rate evolution: Work ongoing to compare rho yields to PS flux before and after "step" in PS rate.
- Polarization status?
Thursday, February 1
- Notes from the previous 24 hours:
- After empty target run, beam intermittent. Trouble setting up V-wire TAC run, due to lock on Active Collimator not providing consistent TAC rate.
- 8 PM start production TAC run with lock on Beam Profiler. TAC rate initially at ~200 kHz, but dropped to 100 kHz overnight.
- 5:30 AM stopped the TAC run and switch to production: target filled, beamline back in production configuration and production run started.
- 16.1 hours of CW beam. ABU: 14.4 hrs (4.9+3.5+6.0), BANU: 1.7 hrs (0.1+0.8+0.8)
- Spreadsheet: number of triggers.
- Low level monitoring
- Issues:
- Run plan for this week:
- Low intensity runs planned for tonight: what is the status of min-bias triggers?
- Today's run plan:
- At 9 AM (or after run production run 41172):
- Harp scans by MCC and Hall D (Hovanes on shift)
- Production running the rest of the day
- At 9 AM (or after run production run 41172):
- Reports:
- Standing issues:
- Rate evolution: Work ongoing to compare rho yields to PS flux before and after "step" in PS rate.
- Polarization status? Came up at MCC meeting, Eugene suggested to report next week.
