As we have no visual of beam coming out of the south LINAC in our usual spectrometer, the SL phase and energy have been drifting all evening, during which we can usually expect to see phase slip downward by something on the order of several degrees. With the two BPMs in dispersive portions of the 2C line being part of chicane one may, with sufficient care (or guesswork), distinguish a shift in energy from a pure shift in orbit. I gently slewed the SL gangphase along so as to move each BPM in the correct direction until I reached the maximum energy gain.

I had to reenable statistics and centroid calculations on the SLM1A camera and also change the I_(7,7) gain from 0.0007 to 0 on account of that cavity being bypassed.

Although the QE is low (see linked entry), the gun current stability has been very good, about 2 uA maximum fluctuations over 75 uA.
