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 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
