Agenda and Notes
1. Operations Status and Summary/Review (Bickley/Drury)
Results of 1L25 FE measurements
2. Energy Reach (Mounts)
RF/SRF issues and current energy reach
14 cavities hard off in North linac 4 cavities hard off in South linac
Lem to 1031/linac has very high trip rate at moment.
Non-symmetrical running leads to loss of polarization in one of Hall A or Hall C
3. General discussion
Action items: Continue analysis of two hour pressure spikes and check module stability after problem solved.  Increase Q_ext to allow higher operating gradient in 4 cavities  Turn on 1L08, in particular cavity three at low gradient. Hold field at low set point to avoid uncontrolled gradient in cavity (cannot be detuned away from fundamental frequency)
