Agenda and Notes

1. Operations Status and Summary/Review (Freyberger)

Four Hall Ops has started. Beam current has been up to about

one pass (300 muA in the

both Linacs) RF not entirely stable yet, but no indication of BBU instability yet. Keeping my fingers crossed. We've had beam loss and lots of separator tuning. Haven't seen clear hot spots. 5 RF trips/hr and 5 MPS trips/hr. Fluctuating RF?

will be increasing current soon.

C75 Review will be held Thursday Feb. 15. Here is the talk repository.

Practice session will be held this Friday, Feb. 9 in this room.
