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 or ~0.5 hour at 240 Hz.
  • 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.
  • (new, Aug 19) Run the Compton DAQ
  • (new, Feb 28) Run the Compton Counting Mode DAQ
