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
Tuesday July 19
Past 24 hours
- Production on Full Pb target 30 nA (~2.8 B events)
- MCC whiteboard - Maintenance Day on Wednesday
Shift Reports
Reports
Issues and Features
- Add the TOF and CTOF trigger rates to EPICs/archiver
- Translation table for rocfdc11 (Justin)
- ROCFDC11 FADC125 slot19 problems (Sergey)
- FCAL FADC250 board died
Plans
- Production data on Full Pb target
- Accelerator will do a 1 hr test plan at 10 am.
- Change to Empty Target
- Tomorrow:
- Safety Walkthrough?
Monday July 18
Past 24 hours
- Production on Full Pb target 30 nA (~3.4 B events)
- Hall C now running at 65 uA. Total beam trips 16/hr, RF trips 10/hr, which is fairly good.
- MCC whiteboard - Maintenance Day on Wednesday
- Doug: Request for schedule update is in progress. Official approval underway; no issues expected.
Shift Reports
(Proposed) Guidelines
- Half-wave plate changes: End the current run. Make a separate log entry indicating new position of HWP (in/out). Start a new run
- Day shift: Check FMWPC gas pressure. Make a separate log entry with current pressure.
Reports
- Current Statistics for CPP-NPP Run (Albert)
- Beam position stability on AC (Beni)
- pi0 update (Beni)
- Rate monitoring (Alexandre)
- Last 3 fa125 itrig errors occurred at event 199961. Go figure. (Naomi)
Issues and Features
- Stability of beam position at Active Collimator
- Add the TOF and CTOF trigger rates to EPICs/archiver
- DAQ windows not updating until window is selected
- FCAL Base lockup
- Translation table for rocfdc11 (Justin)
Plans
- Production data on Full Pb target
- Decide when to go to Empty Target
Sunday July 17
Past 24 hours
- Production on Full Pb target 30 nA (~2.1 B events)
- Hall C is now running at 65 uA.
- Accelerator problems in the evening
- Evening temperatures impacted cooling in building #38 (South Linac - east end). Supplementary cooling was added and stabilized the situation, but facilities may need to help with additional cooling. The are indicators of challenges of running through the summer.
- Thunderstorms affect operation; root causes are not known. Possible causes (Jay): 1. u-phonics induced by the thunderstorms, C-100 cryomodules not adequately damped for 10-80 Hz vibrations, coupled to waveguides to upstairs. 2. Imperfect grounding. 3. micros electrical discharges affecting low level RF. 4. Long helix master RF cable running to south linac in water-filled trough.
Shift Reports
Reports
Issues and Features
- Stability of beam position at Active Collimator
- Add the TOF and CTOF trigger rates to EPICs/archiver
- (Minor) DAQ problems Early Riser Sat, Owl Sunday
Plans
- Production data on Full Pb target
Saturday July 16
Past 24 hours
- Production on Empty target 60 nA (~1.1 B events)
- Hall Access
- Inserted Pb target (Ilya)
- Changed one FCAL base (Malte/Mark)
- Switched SD boards between FDC crates 11 and 12 (Cody/Ben)
- Harp Scans
- Production on Full Pb target 30 nA (~2.1 B events)
Shift Reports
Reports
Issues and Features
- FA125 itrig errors R101072, SD cards swapped FA125 itrig errors R101076
- Stability of beam position at Active Collimator
- Add the TOF and CTOF trigger rates to EPICs/archiver
Plans
- Production data on Full Pb target
Friday July 15
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.
- RF trips at about 13 trips/hr.
- 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
- Need about 6 hours to complete present cycle on empty target.
- Insert Full Target Pb (mid afternoon)
- Change SD card in FDC crate if Cody is available.
- 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
