Information for Expert Shift Workers

Below is a checklist of responsibilities for g2p student shift workers.

Here is the expert shift schedule

Run Information

  • Monitor deadtime, check that prescale values are appropriate


  • Beam charge asymmetry
    • Check charge asymmetry strip chart
  • Check for false asymmetry using scalers/lumis


  • Monitor target polarization
    • Check NMR at beginning and end of run


  • Do full replay for every run (front room will only replay 20,000 events)
  • Check that all ROCs are getting gates
