Agenda and Notes
1. Operations Status and Summary (Freyberg)
Cryo event July 27, Best guess, Oct. 1 for 2 K on one plant. 2 K on both plants on the 25th of Oct. Cleaning He and filling modules presently.
2. "Staytreat" Recap and discussion
Link to 2017 StayTreat Agenda https://www.jlab.org/indico/event/227/timetable/#all.detailed
Highlights: 140 MeV Cryomodule: can we provide it for CEBAF? What is the path? Radiation Calculations in LCLS II Modules. CEBAF up to 2 GeV at 4 K. Gigi talk microphonic concerns from high QL in C75 cavities? See Anne-Marie and Rongli on particulate movement and radiation measurements from FE. Mike Miers talk very interesting and inspiring. Clyde and quench fault discussion: ratio of 50 nsec faults (probably arcs) to slower trip-offs (real quenches) might provide an interesting measurement.
3. Linac Performance (McCaughan)
McCahghan Tech Note on Rebaselining Linac Performance Rebaselining Tech Note 17-039
Action Items
Leadership of quenches. Offline discussion.
