It is not 300 Hz that we should be looking for it is 1495 Hz and 72-ish Hz. Probably in the south linac.

I spent most of the day dealing with data that I took using the SEE BPMs with sample and hold cards that were instrumented using the LabJACK hardware put in place by the I&C folks with software developed by Brian Bevins. In addition to maybe getting a handle on what is going on with the beam I found a few features for Brian to address later.

Noted Scraping w/o C Beam to Lock to

1 day 13 hours ago
Log Number: 4487878Logbook(s): Entry Makers: bschaumlBody: 

I noted some irregularity in current going to Hall B as well as an increase in gamma rates on the IDXs in 5S, 6R, and 2C. I did not realize the severity of the scraping in 2C as the IDX plot on the wall did not have these new detectors on it.

Threw the hall dumplets in, crested gangphase in the NL and SL, ran lower pass locks with C, higher pass locks with B, and all was well. Positional stability and halo rates in B are markedly improved, though that may partially be due to some PID gains I have been tweaking (log incoming) for their orbit lock.
