Summary
RC update 21st March: Yesterday, beam studies was cancelled so we continued with production running through this morning (Kin_x50_0). A few notable events over the past 24 hours.
- SWING shift:Target alarm, Loop 1 & Loop 2 heaters drop (Yellow Alarm). Both recovered quickly without action from the TO: https://logbooks.jlab.org/entry/4269820
- OWL shift: The SHMS angle on the gui is drifting. Will need to have it fixed before any changes to the SHMS angle: https://logbooks.jlab.org/entry/4270036
- Rotation issues. Yesterday and today the HMI needed to be reset (by Ellen)
- BPM position. On March 12th, the 3H07C.XPOS was restored to 0.6 mm (instead of 0.7 mm). Dave Gaskell confirmed this is ok but we should ask return to 0.7 mm at the next kinematic setting.
There was discussion during the RC meeting yesterday about moving the calorimeter to 4 meters (from 3 meters, where we currently are). We have settled on a plan for the next few days. 1.) Today (03/21/2024): At ~9:15 am, with the assistance of RADCON and the Hall C techs, the calorimeter will be moved to 4 meters. 2.) Tomorrow (03/21/2024): In the morning, the calorimeter will be moved back to 3 meters. It will remain at 3 meters through the weekend
- Maintenance Day: Wednesday March 27th
- Site Office Tour
- North Linac will be in restricted
- Plan to lock up at noon
Planned Access to the Hall
- 03/20/2024 - 03/21/2024 (Morning): KinC_x50_0 / NPS = 14.40 deg
- 03/21/2024 - Move NPS to 4 meters: KinC_x50_0b / NPS = 17.61 deg
- 03/22/2024 - Move NPS to 3 meters: KinC_x50_0 / NPS = 14.40 deg
Miscellaneous
- New Run Group in Hall B. Don't worry about the beam polarization. How often should we change the IHWP?
Shift schedule
Sunday March 24th DAY (TO) & Monday March 25th OWL (SL)- Needs to finish Radworker Training (Monday March 25th)
