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
- Monitor edtm scalers
- Check that correct CODA configuration is being used
- LHRS: LHRS
- RHRS: RHRS
Beamline
- Beam charge asymmetry
- Check charge asymmetry strip chart
- Check for false asymmetry using scalers/lumis
- check happex beam current asym: type "asym" or "asym L" or "asym R" in adaq account
- check BPM: type "spot++" or "spot_L" or "spot_R" in adaq account
- Monitor bleedthrough current
Target
- Monitor target polarization
- Check that TO is actively adjusting nmr to maximize polarization.
- Check that target is moved to 2nd cup/annealed when polarization drops too low
Replay
- Do full replay for every run (front room will only replay 20,000 events)
- Check that all ROCs are getting gates
