CHL plans during the summer shutdowns, with emphasis on the impact to the Linac. Topics include: CHL-1 Maintenance summer of 2014, proposed 1.5kW external heater, modifications to support Linacs at 2K on one CHL, and anything else.

17. SRF Maintenance

Mike Drury

4/3/14, 2:40 PM

Planning

Plan and schedule of SRF maintenance work for Summer 2014 (and beyond). Tuner stand-off modifications? tunnel cabling clean-up?

18. RF power Maintenance

Steve Cooper

4/3/14, 2:55 PM

Planning

RF power maintenance planned for the Summer of 2014. R100 Kylstrons installation. Estimated consumables (klystrons, controls) for the next several years of operation.

19. 2.2GeV/pass by Fall 2015 discussion

ALL

4/3/14, 3:10 PM

Planning

Gradient maintenance. What needs to be done? What can be done at 2K? What can be done at 4K? Estimated time needed. Must, Shoulds and Likes

20. RF/SRF Path Forward

Arne Freyberger

4/3/14, 3:40 PM

Planning

With little gradient headroom, constant vigilance is required to achieve peak performance from the RF/SRF/Cryo systems. How shall we proceed? A strawman proposal will be presented and morphed into a robust plan with institutional buy-in from all parties. Peace in the middle east and an end to world hunger will be achieved, as well , during this discussion.
