We couldn't go above 55 uA reliably and were only tripping on BLA, Checked our loss on the relative BLM spikes and we were very similar to the last BLA calibration (see fig 5). Figs 2 and 3 are the sum of all IDX readbacks divided by the current. At the same currents (50 uA), we have less dose. No NDXs are responding to beam. We stopped beam momentarily to hall B and acquired a new constant (+.8% change). The only difference I could see being a factor is that the 3rd pass separator is turned on.

Just before the solenoid trip. Had to steer with 5C11BH to get closer to zero in the x position. This lowered Shield wall IC rates and the hall reported increased photon beam intensity. Locks on at x position zero and y= -1.6
