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? 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).
3. Linac Performance (McCaughan)
McCahghan Tech Note on Rebaselining Linac Performance Rebaselining Tech Note 17-0??
