Hall C has requested 70uA but 2L03-8 and 2L05-1 keep tripping beam (as well as the Hall C diffuser ion chamber) above ~55uA. We tried derating and poff optimization but it didn't seem to help. RF on-call is looking into it but hasn't found anything yet. For now we are staying at 55uA for Hall C.

Hall C Diffuser Ion Chamber IICD307C was tripping when attempting to go above 50uA. Investigations revealed Threshold 3 (Count) remained at 0 while the other ion chamber IICD307B always had a number there and it increased with current (Figs. 1,3). Toggled the Manual button, saw no change, then back to Dynamic and now Threshold 3 (Count) shows 0 with no current, but ramps up with current (Fig. 2). Still not sure why IICD307C Threshold 3 (Count) drops to 0 on trips and IICD307B keeps a number in that field (Fig. 3).
