CREX Detailed Production plan

PREX version

Production Condition Test

1. Check the following has been performed
   • 50uA-70uA beam current, through Compton (backgrounds on fingers and Compton photon detector) with no target
   • Establish 4x4 raster. Insert lead target. (low current, ramp up. check collimator water, vary raster size 4x6?)
   • Set Detector and SAM voltages (Dustin M)
2. Check Conditions OK
   • collimator water
   • thermocouple temperatures
   • radiation monitors
   • ion chamber stability
3. Check 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 beam is going through Compton, HallAComLock should probably be on
   • Should HallAMolLock be on?
4. 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?
5. Pedestals
   • Apply pedestals to japan for SAMs and DETs and compton bpms and cavity bpms. Update bcms and bpms if necessary.
6. 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?)
