RC Meeting Information

RC Daily Meetings are at 11:00 (am) via Zoom and in person in the counting house meeting room (2nd floor)

Useful Links

Hall status

  • DIS singles data for LH2, LD2, Dummy. Carbon data need to be taken before switching to the Positron data taking
  • BCM calibrations:
  • Took 2x30min LH2 data at 16uA
    • Could we increase the LH2 production to 16uA?
  • Completed second production data cycle (first one with 8uA on LD2)


Accelerator status

  • West arc box supplies dropped off at 7am, downtime for ~2.5h
  • Maintenance + Beam study on Wednesday
    • Beam off at 7am
    • Maintenance till around noon
    • Beam study till 21:00pm
    • Beam to the halls, ~22:30pm
    • Scheduled can be shifted a bit if the maintenance work finished earlier

Planned Access to the Hall

Controlled access. RadCon full survey starts around 9am.

  • NPS: Julie, Josh, Aaron to look at the temperature read back issue (3 keys almost whole access?)
  • Walk-thru at 1pm: Joe + 5 FIU students (6 keys)
  • Heidi: checking Dipole, needs one hour
  • Bill: SHMS hut temperature sensor replacement

Current Run Plan

Notices in Effect for Shift Crew

Current Issues

  • NPS crate #2 drops occasionally
    • Not much reported recently, taking 30min runs (restarting a new run more often) seems helping
  • NPS crate temperatures

Special Requests

  • Guard house work till Friday. Pay attention to the sign and follow the directions around there when coming to the accelerator site.
