PREX version, CREX Calibration Plan, CREX Production Plan

Beamline instrumentation calibration - All copied from PREX, updated to CREX numbers

  1. Check detector alignment and pulse height (Done)
    • 1uA Hall A Target BPM lock (with Cavities if required, probably not)
    • 0.2% Carbon
    • 20 nA, cavity locks on and cavities in low current mode
    • VDC on.
    • Check rates, verify pulse height spectra and alignment
    • Modify DAQ to include GEMS. 10 minute run with GEMS.
  2. C-Hole target, verify spot (Done)
    • 20 nA, spot ++ verify raster size
    • harp scan 4e, verify intrinsic size at target
  3. High current - no target (Skip it tonight)
    • verify compton rates
  4. Ramp to SAM Shutter test
    1. Insert Lead Target.
      • Raster 10x10.
      • 20 nA. (Atten 107, slit 15)
      • Cav locks on
      • spot++ verify not seeing edges
      • Set raster ?x? (to get (x.y) = 4x6 real)
    2. Go up in current 1uA (5min)
      • All HV off in HRS hut
      • Target lock (0.6mm, 0.4mm) -> (-0.3, -0.5) is collimator hole center for CREX
      • Collimator water temp
      • Beamline temperatures
      • Ion chamber (stability)
      • SAM yields
      • BCM and BPM yields, widths.
  5. Aaccess to remove SAM shutters, detector to integrate mode.
  6. Ramp to High current test.
      • Cavity bpm back to high current mode
      • All HV off in HRS hut, except quartz
      • Target lock (0.6mm, 0.4mm)
    2. 20uA (review) (10min)
      • Target lock, FFB (monitor bpm Saturation)
      • Collimator water temp
      • Beamline temperatures
      • Ion chamber (stability)
      • SAM and DET yields and widths
      • BCM and BPM yields, widths.
    3. 100uA (review) (10min)
      • Target lock, FFB (monitor bpm SAT)
      • Collimator water temp
      • beamline temperatures
      • Ion chamber (stability)
      • SAM and DET yields and widths
      • BCM and BPM yields, widths.
    4. 150A(1hr)
      • Target lock, FFB (monitor bpm SAT)
      • Aq feedback
      • Collimator water temp
      • beamline temperatures
      • Ion chamber (stability)
      • SAM and DET yields and widths
      • BCM and BPM yields, widths.
  7. Calibration scan, see Calibration Plan
      • FFB ON
      • to 150 uA
      • SAMs HVs set
      • DETs HVs set
      • PITA scan at end to check det linearities later
  8. BMW
      • tune beam, slow lock on (ad FFB on?), exercise BMW, check no ion chamber trips, check pauses locks and FFB
      • low current 2-3uA, exercise BMW, check BPM signals, check no ion chamber issues
      • target in, low current 2-3uA,exercise BMW, check BPM signals, check no ion chamber issues
      • "ready for high current"
