Agenda and Notes
1. Operations Status and Summary/Review (Freyberger)
Four Hall Ops has started. Beam current has been up to about 300 muA total in 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?
Because no hot spots observed, will be increasing current soon.
C75 Project and Implementation Review will be held Thursday, Feb. 15. Here is the talk repository.

Practice session will be held this Friday, Feb. 9 in this room.
2. Installation of FEL Cryomodules (Baggett)
The F100 and SL21 cryomodules from the FEL will be moved to CEBAF. F100 will probably replace lowest-performing C100 and SL21 will replace a C20. Specific choice not completed yet but there is a strong desire to have a C100 available for investigation and refurbishment.
