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
