Still trying to find out a cause, maybe the injector? A3 interception did go up after the BLMs went quiet, as did A4 and interception on the master slit, though only slightly. I can't find anything that drastically changed yet. The BLMs are still on and communicating, we have gotten a 7S01 trip since.

Hall C Compton Ion Chamber rates have improved as well.

I don't want to look gift a horse in the mouth, but I wouldn't mind an explanation.

Hall C charge asymmetry was averaging ~ - 200 at the beginning and drifted to ~ - 300 ppm during run 16182.

I ran the feedback at the beginning of run 16183 (12:42 - 13:00 hrs), that changed the Hall C IA setting to 56514 from 57123. Hall A PITA setpoint was also changed to 9665 from 9609.

Charge asymmetry in Hall A is averaging ~ - 11 ppm in this period.

Had a two trips of 0L04 so far on shift, so we ran check tune and adjusted cavity 2's TDOFF -6 degrees in hopoes this will help it out.
