PREX version, CREX Calibration Plan

Production Condition Test

  1. 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)
  2. Check Conditions OK
    • Collimator water
    • Thermocouple temperatures
    • Radiation monitors
    • Ion chamber stability
  3. 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!
  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?)
