Agenda and Notes

1. Operations Status and Summary/Review (Bickley/Drury)

Action items:[1] Continue analysis of two hour pressure spikes and check module stability after problem solved. [2] Increase Q_ext to allow higher operating gradient in 4 cavities [3] 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)

2. General Discussion (Krafft)

Resume every other week meeting on RF/SRF issues.

Focus on OPS issues near term; get back to long term focus in longer term.

Charlie's new team.

3. Progress on Particle Counter (Geng/Spata)

Particle Counter getting closer. Now design is focusing on "laser blanket" for aperture design. Detect phase shifts in interferometer arrangement.
