Friday July 16
Past 24 hours
- RF Recovery Day
- Productive Recovery
- Slow orbit drifts investigated. Source: changing up of a screen. Longterm solution will be implemented with long shutdown, requires vacuum work. Short-term: increase apertures, possibly this weekend.
- Restoring to more stable configuration. Delivered 70 uA to Hall C for short period and ran 48 uA overnight.
- Maintenance
- Access to investigate DIRC environment parameters (Nick)
- Access to install crystals for testing in the PS Test Setup (Vlad and Sasha)
- DIRC Environment (Tim)
- Recycled power on BCAL LED crate (Elton/Mark)
- FCAL Base Replaced (Malte/Mark]
- Program when beam comes back
- Solenoid ramped up to 1350 A (Tim)
- Beam back about 9 pm.
- Production on Empty target 30 nA (~0.08 B events)
- Production on Empty target 60 nA (~1 B events)
Shift Reports
Reports
- Single pi0 production (Beni)
- omega signal in FCAL (Simon)
Issues and Features
- Stability of beam position at Active Collimator
- itrigger errors in monitoring plots
- Hydra not running (Naomi)
- Add the TOF and CTOF trigger rates to EPICs/archiver
Plans
- Insert Full Target Pb
- Harp scans
- Production
Thursday July 14
Past 24 hours
- Request for a Schedule Adjustment from Jul 27 to Aug 17 has been submitted.
- Production on Full Pb target (~0.5 B events)
- Install Empty Target (12 pm)
- Production on Empty Target (~0.9 B events). Need about twice that. After checking statistics today, I suggest we stay on Empty Target, but run at 60 nA after maintenance.
- Storm Takes Down Accelerator
- Smooth, but trippy, beam after recovery. Trips are at about 15-20 trips/hr
Shift Reports
Reports
- We would like to add the TOF and CTOF trigger rates to EPICs/archiver
Plans
- RF Recovery today (beam down 8.15 till ~5pm)
- HD Refrigerator Maintenance
- Access for Sasha and Vlad to install modules in PS Test Stand
- Nick to work on DIRC environment
- Following Maintenance: Plan to continue with Empty Target data to complete the data taking cycle and then continue at 60 nA
