Body: Fopt 7.7 completed successfully. The runtime settings include a sample count of 15, a minimum current of 4, and an operating regime of Standard with Excitation in 1S Region. The corrector and RF kicks applied were 1.48165 and 1.48165 volts respectively. The max. amplitude setting was 1 millimeters. The files for this run were saved in the directory /cs/opshome/hlapps/optics/diforb/24apr241756. The X and Y stability of the machine during the run was 0.0902984 and 0.0575626 (mm) respectively.

Initially Hall A charge asymmetry was drifting towards negative and Hall C charge asymmetry was drifting towards positive.

Accelerator was down due to Injector Checks. When the beam came back, charge asymmetry was drifted to ~ - 350 ppm for Hall A and ~ 450 ppm for Hall C.

I ran the feedback during run 16043 for ~ 10 min (13:31 - 13:44 hrs) that converged both the asymmetries close to zero.

IIX6E02 peaking at several hundred rad/hr, figure 3. NDX7A15 and 8A15 normally see nothing but that's not the case since 0700 this morning, figure 2. IIX8E02 higher than it should be, but tolerable, figure 1. BLA loss signal high even though calibration was done around 1000, bottom panel of figures 1 and 3.
