keyword=Charge asymmetry response to Hall-CBelow I show how the charge asymmetry responds to Hall-C beam current during run 2300. Appears to jump up by 100ppm when the Hall-C beam current is gone. Charge asymmetry for Hall-C still appears to be zeroed (disregard the statistics... it includes time when hall-C is off). The bleedthrough appears to have a somewhat large effect on our charge asymmetry. Maybe we should decrease the timescale of our charge asymmetry feedback to attempt to compensate for the jump in beam charge asymmetry whenever Hall-C turns off.
