    Comments: We did a test at the injector with Matt Poelker that demostrated a linear dependence of Hall A current on Hall C current implying cathode charge limit effects are causing our current drop when Hall C is on. An RF zone lost HV, causing a brief down. Compton did some brief low-current scans.
