Detector checkout and calibrations

Additional instructions:

  • We run both the COIN and separate DAQs during this phase!
  • Inelastic measurement:
    • Take 5min of MODE 10 data before starting the the inelastic measurement, then switch back to MODE 9.
  • Coinc elastic:
    • Take 5min of MODE 10 data before starting the the inelastic measurement, then switch back to MODE 9.
    • Take pre-scaled 3/4 singles in both arms, set pre-scalers so the singles rate is <100Hz
    • This run needs a special temporary trigger that will be connected to PS5
    • Make sure sure PS5 = 0

Unscheduled single-arm Run Plan

COMPLETED

Replaces original radiator and production trigger checkout. Click here for the single-arm SHMS run plan

Coincidence elastics

  • * Trigger:
    • run with ps6=0
    • Remember to click "save" when changing the pre-scalers!
  • J/psi-007 Instructions for Shift Takers
    • Do a 50k replay for every run. Carefully check the monitoring plots and discuss anything that looks strange with the analysis shift crew.
    • Fill out the Shift check list once every shift

  • MODE 10 runs:
    • Set DAQ to MODE 10 and click "save" in the pre-scaler GUI
    • Remember to go back to MODE 9 when done (and click "save" again!)
  • J/psi-007 Instructions for Shift Takers
    • Do a 50k replay for every run. Carefully check the monitoring plots and discuss anything that looks strange with the analysis shift crew.
