Outline LERF Setup and LCLS-II’s contribution Roles and Responsibilities in setup Main Objective for LCLS-II Additional Benefits Operation Support (or not) A.Ratti, J. Schmerge, Transition to Operations Review: LSCL-II Cryomodule Commissioning in LERF

LCLS-II Setup at LERF LCLS-II provided most of the electronics and control systems SSAs LLRF controllers CryoModule controllers These are all production units needed back at SLAC before the end of construction and the beginning of commissioning JLAB contributed significant local support Networking and Local Controls All installation, cabling, RF power distribution, AC power…. All cryogenic system connections and interfaces Funding to ship the equipment back to SLAC was allocated to JLAB Relative roles and responsibilities described in a dedicated ICD - LCLSII-2.7-IC-1116-R0 A.Ratti, J. Schmerge, Transition to Operations Review: LSCL-II Cryomodule Commissioning in LERF

support cryomodule production testing and qualifications Main Goals for LCLS-II First and foremost support cryomodule production testing and qualifications expedite production and help maintain an aggressive schedule A.Ratti, J. Schmerge, Transition to Operations Review: LSCL-II Cryomodule Commissioning in LERF

Other benefits to LCLS-II and its personnel Testing and integration of all LCLS-II Electronics and Controls for two cryomodules Similar setup to L1 Gain experience, complete integration Learn CM testing with LCLS-II Hardware Integrate cavity measurements and testing infrastructure in place at CMT* facilities A.Ratti, J. Schmerge, Transition to Operations Review: LSCL-II Cryomodule Commissioning in LERF

Operating the LERF setup Funding from LCLS-II at SLAC does not include cavity/cryomodule testing and/or operations Troubleshooting and Support for running the systems in LERF will come from SLAC on an as needed basis as part of the development of each subsystem involved We are looking for funding to support training of SLAC staff in operating and testing SRF cavities and cryomodules A.Ratti, J.
