Monday, Mar. 18 at 08:45
- Past 48 hours:
- Issues
- Reports
- Daily FCAL update
- Daily compcal RF timing discussion
- Today
- Halls B and D only halls at 5 pass. We're both at low current and MCC can not see the beam in the machine, only when it enters our halls. Beam trips may take a little longer to recover, so they asked for us to be patient.
- MCC looking into noisy BPMs (calibration issue?). They're looking into this now.
- Run Plan
- Empty target running with standard production setup.
- What else can be done about the beam position to ensure a successful TAC run?
Friday, Mar. 15 at 08:45
- Past 24 hours:
- Short access after meeting
- gluon01 is back with a new kernel and graphics driver
- Production running
- Issues
- Problematic FCAL channels near beamline
- One base lost connection and was recovered by power cycling the power supply. This happens 1-2 times per week. Right now I (Colin) am the only one capable of doing this. Need to train more people how to spot and fix these errors. It is a relatively simple process, but one that should not be left to the shift crew.
- One base lost HV near beam line.Follow up. Access to replace after morning meeting. Friendly reminder: please do not call Colin at night about base problems. Emails and texts are fine.
- Monitoring problem with file/DB management. Usually does not happen
- David and Thomas looking into CCAL pedestal Rootspy issue. Appears to be a Rootspy display issue and Dave will investigate more next week.
- Reports
- Today:
- Production: 200nA, Al 10-4
- Run Plan
- Production running
- TAC run
- Hall A performing beam modulation studies Tuesday owl shift. Will cause 1 MeV fluctuations in beam energy. They will do a test Monday morning from 8-9am.
Thursday, Mar. 14 at 08:45
- Past 24 hours:
- Production running
- Issues
- RootSpy Problem with CCAL Pedestal Histograms
- Hall D y position variation from Jay. Beam position variation not related to dispersion.12
- Console 1 frozen. Who knows how to reboot?
- Reports
- Rate monitoring (Alexandre)
- FCAL shift in simulation (Liping)
- Beni really wanted to conitune our discussion yesterday on histogram binning (Beni)
- Today:
- Production: 200nA, Al 10-4
- Run Plan
- Production running
- Hall C goes down Sunday at 4pm. Postpone TAC run until Monday unless there are objections.
- There are parity quality beam testes (PQB) scheduled for Hall A Monday and Tuesday, but this should not affect the beam delivered to us.
- RF Recovery scheduled for Wednesday
