Beamline instrumentation calibration
- 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.
- Set Detector and SAM voltages (Dustin M)
- Check Conditions OK
- collimator water
- thermocouple temperatures
- radiation monitors
- ion chamber stability
- Setup 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?
- Coordinate
- Should Compton and Moller DAQ be running during calibration?
- Dustin and Devi examining SAMs and Detectors with online analyzer during calibration
- Juan Carlos/Amali/Adam monitor Compton background rates and run the DAQ?
- Calibration Procedure A: with UNSER
- start at 70uA for 1min (scandata1==value in BCM0l02)
- beam off
- wait for 5sec(for unser to equilibrate), take unser pedestal data point for 30sec (scandata1=0)
- beam on at 75uA
- check slow target lock is in position
- check FFB on for HallA
- check no bpms are saturated on iocse9
- wait for 5sec(for unser to equilibrate), take next data point for 1min
- repeat for 65uA,60uA,55uA,50uA,40uA,30uA,20uA,10uA
- Calibration Procedure B: with pre-calibrated Hall BCM (analog upstream bcm)
- start at 70uA for 1min (scandata1==value in BCM0l02)
- change current to 75uA
- check slow target lock is in position
- check FFB on for HallA
- check no bpms are saturated on iocse9
- take next 1min data point
- repeat for 65uA,60uA,55uA,50uA,40uA,30uA,20uA,10uA
- Calibration Procedure C: for BPMs (Compton bpms not yet calibrated)
- at 70uA, set gains off for iocse9,iocse10 (Hall) iocse11,iocse12,iocse19,iocinse4 (Inj)
- rperform Calibration Procedure B with pre-calibrated Hall BCM
- Beamline instrumentation calibration 0.5 shift Caryn P,
- Current ramp for BPM/BCM calibrations and detector pedestals detailed plan
- Initial production condition test 0.25 shift Caryn P,
- detector and SAM widths
- regression sensitivities
- beam noise and asymmetry check
- collimator water and thermocouple temperatures,
- radiation monitors and ion chamber stability
- Width studies 0.5 shift KK,
- detector and SAM widths, targets, shutters, etc
- deinstall shutters at conclusion of test
