Current Status
- Good beam overnight. Finished with ~2 hrs on Dummy target for Phase-1 kinematics.
- "RF Recovery" started at 8. Went to controlled access and Steve did some work in the hall.
- Rotated and set magnets for Phase-2 kinematic
- Beam came back around 1:30pm and pretty bad since.
- Will continue running J/Psi on kinematic Phase-2.
Current Run Plan
- J/Psi Experiment:
- Run Production Phase-2. Shooting for a total of 6.5 C for phase-2 kinematic before returning to Phase-3.
Notices in Effect for Shift Crew
- Shift Leader is responsible for 50k replays. Even if the TO is actually doing them.
- Target Operators: When the alarm handler goes white, it is disconnected from the IOC. Log it and include carlin@jlab.org every time. Acknowledge the warning. If it is still white and not coming back, restart the alarm handler. Do not permanently silence the alarm handler.
- Missing Reference Times during the replay: check in the 50k. Check in full replay, if able. If it happens, call RC. Guidance to solve it is here: https://logbooks.jlab.org/entry/3654584
Current Issues
- SHMS Q1 and Dipole communications fixed.
- HMS Dipole power cycled to fix odd behavior.
- HMS Q1 and Q3 PSU M-panel (local front panels) are showing signs of failure. No action taken at this time.
- Ethan installed a current limitation board on the HMS Q2 spare PSU. Currently it is set to ~700A.
- Some de-icing of SHMS leads.
- Rotation Controllers turned back on and left on this morning.
- Concerning target alarms (loss of cooling power/over head) continued when running with hall A.
Planned Accesses to the Hall
Planned Accelerator Configuration Changes
Special Requests
- Latif's GEM testing completed this morning during beam studies.
