- Notes from the past 24 hours:
- Beam off from 8am-3:24pm due to high beam current push for Hall C and then RF recovery. After than some bean during swing shift and good beam during owl.
- We did an access while beam was off:
- Acess for DIRC
- Beni Adjusted CDC gas flow.
- We did an access while beam was off:
- PS thr. scan finalized.
- DIRC production data taking over night
- Beam off from 8am-3:24pm due to high beam current push for Hall C and then RF recovery. After than some bean during swing shift and good beam during owl.
- Issues
- Current limited at 150 nA(diamond)/50nA(amo) due to DAQ problem.
- [1], [2] ,[3] DAQ lifetime dropped to zero many times (I counted 8).
- TOF RF status?
- Beam current can drift by 10+ MeV. Do we care?
- Today's plan (changed this morning at the 8:00am MCC meeting)
- Beam scheduled for all day: DIRC commissioning+Thr. scan+LED&dark runs+data taking overnight.
- MCC white board
- This week time chart
- Hall D white board

- Notes from the past 72 hours:
- Beam restoration, system checkout and start of DIRC commissioning going well.
- Issues
- Harp at 5C11, Harp at 5C11b, Hall D harp+ fit, Coherent peak as of this morning Beam convergences probably bad. Do we want to address this?
- [4], [5] DAQ lifetime sometimes drops]
- TOF RF status?
- DIRC Commissioning with beam over weekend:
- Today's plan (changed this morning at the 8:00am MCC meeting)
- 8am-9:30am: High beam current push for Hall C. At best, low quality beam, very trippy. We maintain the planned access for Hall D
- 9:30am-??12:30pm-2:30pm?? RF recovery: No beam
- After RF recovery: spin dance for Hall B.
- Minimally invasive: 2 or 3 instances of 20 min beam off for spin angle rotation at the source. Beam available in between.
- Restart DIRC commissioning.
- MCC white board
- This week time chart
- Hall D white board
