Hall B attenuator weirdness
We have been seeing some weird things with Hall B's current and attenuator. It started when we first tried to send beam back and the normal 130 minimum attenuator setting couldn't produce enough current to kick the current lock on and has needed to be set to 175. Hall B's attenuator spiked to 381 because they lost the 5nA they have requested for their harp swipes, and at this same time A3 interception spiked from 3.7 to 5.2. Beam tripped off and when attempting to send back their attenuator jumped to 443 and no beam being sent. All of the sudden beam was sent to B and tripped max juice.

Archiver generated iCalibration for xC LH2 10cm, Pass 4, NPS Off
We tried to do a calibration up to 30 uA using the calibration tool but we could only get to 20 uA before BLA trips started. Had to abort it, and it does not give the option to save the existing calibration data.
I used the script to generate an ion chamber calibration based on archiver data over the period where we attempted to calibrate earlier, Fig 1.
