Back to Run Coordination Meetings:Summer2022
Meeting are via ZoomGov: connect (Meeting ID: 160 199 0060 / Passcode 8394)
Hall D counting room white board
Contents
Wednesday July 27
Past 24 hours
- The accelerator went offline at 5:30 PM Tuesday due to a power glitch to CEBAF. The Tagger and PS magnets tripped off. Waiting for issues with a RF zone and a bulk power supply to be resolved
- Data taking on Pb target, approx 1.0 B triggers in the past 24 hours
Shift Reports
Reports
- CDC HV trip Hovannes
Plans
- When beam returns take harp scans, then resume data taking on Pb full target
- Thursday day shift is scheduled for beam studies, beam in the accelerator but not to the halls. This would be a good time to work on the CTOF PMT#3
Tuesday July 26
Past 24 hours
- Switched to Pb target around 10:30 AM Monday
- Data taking on Pb target, approx 2.8 B triggers in the past 24 hours
Shift Reports
Reports
Plans
- Continue taking data on full target
- Next opportunity to repair CTOF PMT #3 is probably Thursday, tentative RF recovery day
Monday July 25
Past 24 hours
- Data taking on empty target, approx 2.7 B triggers in the past 24 hours
Shift Reports
Reports
- Some TagH scalars are high with no beam A. Hurley
- Nice clean omega Beni
Plans
- Switch to full target running after the RC meeting
Sunday July 24
Past 24 hours
- Data taking on empty target, approx 2.8 B triggers in the past 24 hours
Shift Reports
Reports
- 3 bases and 1 PMT swapped in FCAL Mark
- Discriminator problem in rocTAGH2 slot 18 Hovannes
- Tagger hodoscope scalar channels frozen Thomas
Plans
- Continue taking data on empty target until Monday morning.
Saturday July 23
Past 24 hours
- Data taking on empty target, approx 2.7 B triggers in the past 24 hours
Shift Reports
Reports
Plans
- In discussions Friday after the RC meeting it was decided to continue data taking on empty target until Monday morning. Then switch to full target.
Friday July 22
Past 24 hours
- Data taking on empty target, approx 2.1 B triggers in the past 24 hours
- Priority for beam delivery shifts to Hall D today
Shift Reports
Reports
- Followup on backgrounds seen in coherent pi0 photo-production on lead] Beni
- Updated firmware for fadc250 rocfcal2, slot13 Sasha
- FCAL Hit Local Time after the fix
- Trigger rates with amorphous radiator and empty target Y. Wolf
- TOF and CTOF trigger rates recorded to EPICS Sasha
- CTOF paddle 3 PMT tripped David L.
Plans
- Continue data taking on empty target until ~ 17:00 today, then switch to full target for running over the weekend
Thursday July 21
Past 24 hours
- ROCFDC11 Slot 19 FADC125 (possibly?) repaired
- Solenoid final ramp to 1350 A ~ 5:00 AM
- Beam returns ~ 5:00 AM
- Harp scans
- Start data taking on empty target ~ 6:00 AM
Shift Reports
Reports
- see etas Beni
- 7 FCAL bases changed Mark
- Changed CPP chamber gas flow Tim
- HD solenoid update Tim
- Strange solenoid MPS GUI state Hovannes
- Solenoid final ramp to 1350 A Tim
