Summary
- Yesterday, while attempting to bring us back to production, there was a vacuum issue in the NE spreading.
- have been down since ~11 am yesterday. Prior to the vacuum issue, the calorimeter was moved from 3 to 4 meters. Unfortunately, no data has been taken at this 4 meter setting.
- This morning, will move the calorimeter back to 3 meters in anticipation of the resumption of beam.
- While beam has down, a short access was made into the hall during the SWING shift. Module C3-R3 was replaced.
- A full summary of the activities can be found in Josh's logbook entry: https://logbooks.jlab.org/entry/4270285
- LED runs were taken during OWL shift.
- Presently, work continues to address the vacuum issue. They expect to have a clearer idea about the timeline for resuming beam delivery around noon today,
- PMT bases surveyed and removed from the hall
Planned Access to the Hall
- 03/22/2024 - Move NPS to 3 meters: KinC_x50_0 / NPS = 14.40 deg (Completed)
Possible plans while we wait for resumption of beam
- LED (Magnet on & Magnet off) / Cosmics?
- Alternate HV settings?
- Other suggestions?
Future Plans
- Current Kinematic: KinC_x50_0
- HMS angle = 25.940 deg, HMS Momentum = -2.638, SHMS angle = 30.700 deg (NPS Angle 14.400 deg)
- Proposed plan: Change kinematic setting on Saturday
- Tuesday (03/26): Moller measurement
Miscellaneous
- Site Office walkthrough ~ 15 - 30 minutes on Wednesday (will need to be out of the hall).
- Doug will try and coordinate to let us know the time so we can prepare
Shift schedule
- Is beginning to fill up
- TO Sunday OWL: Trade request
- TO Sunday DAY: SL needs to have walkthrough (SAF112)
- TO shift for OWL and SWING (Monday - Wednesday)
