Agenda and Notes

1. Operations Status and Summary/Review (Freyberger)

During SAD two FEL modules being moved into NL07 and NL23 (a C100 is being removed). This first C100 cryomodule will be used as a feeder for the C100 refurbishment program. More on this below.

Current limits from previous minutes largely solved, if not completely understood, by injector tuning elliminating beam haloes. Bunch length changes were effective in mitigating problem. Process Reza used could be incompatible with high quality parity measurements.

Some questions about HOM loads as installed in CEBAF. P1 FEL configuration for all cavities after installation back in CEBAF.

2. Magnetic Flux Generated by Thermal Currents (Geng)
