We will calibrating Hall C as that is the only hall capable of recieving beam. BLA Loss profiles are abnormal, showing constant integrated loss and more current in Hall C's BCM than in the Injector's, clearly indicating that the BCMs are mismatched. We performed the FC2 to 0L02 Calibration and BLA Confidence Test. Aperture scans look good, no BLMs were tripping with BLA, wire sums are good, NDXs are quiet, and IDXs are also quiet.

The only BLA fault indicated is for the downconverter in Hall A, which is to be expected.

Ran through the relevant BLA test sources. The only exception, which is expected, is Hall A; the downconverter is masked and the readback shows no current when the test source is on. Otherwise, all is nominal and pictured below.

IBC0L02 to FC2 Calibration

Followed the procedure for this calibration and the cal factors hardly changed. Currents agree on the low end but IBC0L02CurrentB diverges from the others above about 20 uA. This is probably a matter of interpretation in the procedure as it seems like it could be read as instructing the operator to monitor current while stepping down from 10 uA to 0, but I decided to check the full span of the currents we are calibrating for. The important PVs, IBC0L02Current and FCupsCORRECTED match very well, so I am comfortable calling this done.
