Agenda and Notes

1. Operations Status and Summary/Review (Bickley)

New Module a good performer. It's doing about 105 MeV. Cavity two had vacuum issues solved by setting to 19.5 MeV. Best cryomodule in the machine now. Cavity Eight had a low onset of FE, running at 12.5 MeV; running now without FE.
