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.
