Agenda and Notes

1. Operations Status and Summary

Piezo work started on R100. Should be possible to get some microphonic damping. Stay tuned, code/software problems.

Regular beam studies on Tuesdays and thursdays for RF recovery.

One hour machine ops devoted to Fast X-ray detection of FE, able to tune for reduced losses in . Establish baselines for future comparisons.

C100 tests (determine best pressure "defined by highest operating gradient" to operate at)

Got 70% of cavities back up to E_maxop values, but were having cooling/instability problems when operating at high values.

destinguish/study SEL GDR trip differences (Rama)

Future mechanical investigations to elliminate vibrations in the first place may be appropriate going forward.

2. Superinsulation Damage? (???)

3. R&D for improving and maintaining CEBAF gradient (in situ?)
