Halo rates in Hall B continue to be a bugbear. Restored beam after injector work shows greatly elevated upstream halo rates. Attempts to adjust the angle with steering to the 2C21A nanoamp BPMs yielded no joy. Even after removing their collimator (figure 2), rates are still well above where they were earlier in the day. Returning to running to the tagger to resteer the line.

Injector drifted, which caused the interception on apertures to increase. Corrected the drift.
Fig. 1: After correction, 400 laser attenuation generates 161nA cw beam for Hall B, 1.77 uA on A1, 0.73uA on A2, 2.67uA on MS
Fig. 2: Before correction, 657 laser attenuation generates 141nA cw beam for Hall B, 10.4 uA on A1, 2.37uA on A1, 8.61 uA on MS

The shift is most pronounced in the horizontal, but the entire hall line's orbit has shifted after running path length. Frustratingly, halo rates have remained relatively unchanged according to the archiver, but halo rate trips are now constant, and nowhere close to the set trip point of 1 million Hz. It makes me question why we use these diagnostics if the reported values appear to have no bearing on the actual trip point.
