  2. Issues:
  3. Today's run plan Google Calendar:
    • Production running
    • 10 am: Min-bias trigger setup (Sasha)
    • 11:30 am: High intensity test (Sergey)
  4. Reports:
  5. Standing issues:
    • Rate evolution: Work ongoing to compare rho yields to PS flux before and after "step" in PS rate.
    • Polarization status?

Thursday, February 1

  1. Notes from the previous 24 hours:
    • After empty target run, beam intermittent. Trouble setting up V-wire TAC run, due to lock on Active Collimator not providing consistent TAC rate.
    • 8 PM start production TAC run with lock on Beam Profiler. TAC rate initially at ~200 kHz, but dropped to 100 kHz overnight.
    • 5:30 AM stopped the TAC run and switch to production: target filled, beamline back in production configuration and production run started.
    • 16.1 hours of CW beam. ABU: 14.4 hrs (4.9+3.5+6.0), BANU: 1.7 hrs (0.1+0.8+0.8)
    • Spreadsheet: number of triggers.
    • Low level monitoring
  2. Issues:
  3. Run plan for this week:
    • Low intensity runs planned for tonight: what is the status of min-bias triggers?
  4. Today's run plan:
    • At 9 AM (or after run production run 41172):
      • Harp scans by MCC and Hall D (Hovanes on shift)
    • Production running the rest of the day
  5. Reports:
  6. Standing issues:
    • Rate evolution: Work ongoing to compare rho yields to PS flux before and after "step" in PS rate.
    • Polarization status? Came up at MCC meeting, Eugene suggested to report next week.
