Beamline commissioning log:
Next step is calibrating ion chambers for carbon hole target:
04:11 -- MCC sending tune beam into hall (empty target)
04:21 -- MCC verified beam position on dump viewer. With 10uA on empty target, ion chamber readings 800-900 rads/hour.
04:42 -- MCC adjusting BPMs to A=(0,0), B=(0,0); ion chambers back near 200 rad/hr as during test earlier tonight. MCC testing up to 30uA.
04:49 -- moving to carbon hole target. start calibration of ion chambers on this target with 4x4 raster in MCC units.
5:25 -- moving target back to empty for last step of calibration.
5:29 -- MCC is done calibrating ion chambers on carbon hole target. Requesting survey for controlled access.
Commissioning procedure for Pb targets isn't done, status report will follow.
