Agenda and Notes
1. Operations Status and Summary/Review (Freyberger)
High average current limits remain. Usually A runs 22.5 muA and C runs 50-60 muA. Seems more and more solid that the Hall C current limit is 70-75 muA, independent of the Hall A current. And the main trips are from beam loss. So focus is shifting back to injector. Today, bunch length measurements are being made for the different Hall bunches. Recent work points to longitudinal phase space tails causing high average current trips. Is there a better diagnostic for these?
Anna will be working on getting a handle on OPS-initiated reductions in the C100 cavity gradients. First try to understand why people are reducing them and work through mitigations.
