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.
  • 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
