PREX Main<< Information for Shift Takers << Shift Leader


Overview of Shift Tasks

  • Ask the expert (back room) if something is unclear.
  • Start / stop runs using the Parity DAQ (apar@adaq1). Keep runs <430 K events, about 1 hour.
  • Verify that Charge Asymmetry feedback is running. The data are practically useless if not.
  • Verify that Beam Modulation is running
  • Look at the Panguin ("online analyzer") plots
  • Analyze ("fast prompt") each run and review the prompt plots.
