PREX Main << Information for Shift Takers

Assist shift crew in data taking as needed
- help diagnose and solve CODA issues
- answer questions about plots in Panguin
- remind the TO to check the Panguin plots frequently
Makes sure online analysis is up to date
Look at beam quality
- Look at runs from a previous good period and compare to the current runs
- Watch for changes in means and widths over time
- Log anything that you think is an issue that needs to be investigated and email the WAC
Decide when to change IHWP settings
- Each slug should have ~8 runs, but the real measure is a total charge of at least 1.2 C (but not too much more than this)
- Keep track of the accumulated charge in the slug using the counter
  - If the current run had steady beam and no known issues, check the accumulated charge before it ends
  - If the accumulated charge is >1.2 C including all runs but the current run, and the current run is good, you can probably increment the slug
  - Ask the shift leader to follow the instructions at Flipper
