Agenda and Notes

1. Operations Status and Summary/Review (Bickley)

Physics run extended and two weeks added to shutdown. Good reliability running at low energy. Re-planned summer maintenance work. Full E' plan will be executed. Low energy setup with reduced heating accomplished.

Plan for module swaps complete.

2. In Situ Q_L Measurements (Marhauser)

Presentation on Q_L Measurement

3. Some Comments on particulates (Geng)

Many valve closure tests completed and log entries made. Particulates ranging in size from sub-micron to several microns are observed in the tests.

Action Items

Leadership of quenches. Offline discussion.
