PREX version, CREX Calibration Plan
Production Condition Test
- Check that the following have been performed
- 150uA beam current, through Compton (backgrounds on fingers and Compton photon detector) with no target
- Establish 2x2 (actual) raster. Insert Production Test target (ask Experts which one, probably Ca48). (low current, then ramp up. check collimator water, vary raster size?)
- Set Detector and SAM voltages as needed with these target rates (Dustin M, Devi A)
- Check Conditions OK
- Collimator water
- Thermocouple temperatures
- Radiation monitors
- Ion chamber stability
- Set up Locks (these are necessary for main detectors and SAM calibration)
- Slow Target Lock on 4A, 4E (jmenu->"slow locks"-> Orbit Locks Expanded View -> HallATGT)
- Fast feedback for HallA on (iocse9) -> If it has been properly commissioned by OPS already, otherwise it can be done later
- If beam is going through Compton, HallAComLock should probably be on
- Should HallAMolLock be on? -> No!
- Parity
- establish Aq feedback on bcm_an_us
- document pqb conditions
- turn on Helicity Magnets? -1000,1000 for first 2 and -200,200 for second 2?
- Pedestals
- Apply pedestals to japan for SAMs and DETs and compton bpms and cavity bpms. Update bcms and bpms if necessary.
- Take Data
- Take at least 1 hour of data
- Monitor all things above and take screen shots of all parameters above and elog them.
- Run panguin online to examine feedback, Detector widths, Monitor Widths
- Regression slopes check from Tao
- examine simple correlation plots with panguin (are SAMs and DETs normalized in mul tree?)
