Agenda and Notes
1. Operations Status and Summary
Got 12 GeV to Hall D. 10s of muA delivered to Hall A. Trip Rates OK, but long down times from whole module downs. C100s(powers supplies).
8:20 pm saterday, All 10 Hz noise disappeared. Cooling power fan. Now up to 110 MV. We'll look at this in more detail. phase correlations among cav 5s in each cryomodule.
when not running machine, have no indication of problems in environment. Install accelerometers as permanent monitor.
Tom agreed/volunteered to vibration monitorring independent seeing it in the RF systems.
RF/SRF Round-the-clock during recent operations period.
Energy jitters are still present on beam.
Both north and south now operating at lower pressure and temperature.
Max OPs should be looked at again for a few specific cavities.
2. Module up to air investigation (Reece)

cells and HOMs frank cryomodule design ed Hygeine plan gigi R100 RF hovater
Piezo tests again?
- First Draft version is attached below, modeled on tables in the
Cornell ERL "Project Definition Design Report". It contains input from Rimmer, Hutton, and Krafft but needs work on the cryomodule side. Daly and Mounts to help complete. Arne to derive cooling power requirement for charter document. Arne suggested publishing in tech note in about 6 weeks. Krafft will shepherd.
4. CEBAF Beamline Vacuum (Geng)
Action Items
Complete Project Charter Document; Project Leader (Freyberg, Rimmer, Krafft, Hutton)
Data mining for field emission (Geng)
C75 parameter table! (krafft, rimmer, marhauser)
Heat For Project Charter (freyberger)
