    • This is likely to continue through the end of day shift

Feb 05 Swing

  • We start with kin 15 for the left HRS, and keep taking data at kin 16 for the right HRS. Please follow the run plan from the white board when we get beam back.
    • If beam gets unavailable for more than one hours, run carbon hole when beam is back to make sure it is centered. Then go back to continue with "rounds" of (3He, 3H, 2H).
  • Double check our Shiftworker Jobs and Responsibilities to make sure all activities needed from you are on track.
  • Any question? Call the RC if needed.

Feb 05 Day
