TI - LCLS-II Fundamental Power Coupler Mechanical Integration J2 - Proc. of International Conference on RF Superconductivity (SRF2015), Whistler, BC, Canada, Sept. 13-18, 2015 AB - LCLSII is a planned upgrade project for the linear coherent light source (LCLS) at SLAC. The LCLSII linac will consist of thirtyfive 1.3 GHz and two 3.9 GHz superconducting RF continuous wave (CW) cryomodules that Fermilab and Jefferson Lab will assemble in collaboration with SLAC. The LCLSII 1.3 GHz cryomodule design is based on the European XFEL pulsed mode cryomodule design with modifications needed for CW operation. The 1.3 GHz cryomodules for LCLSII will utilize a modified TTF3 syle fundamental power coupler design. Due to CW operation heat removal from the power coupler is critical. This paper presents the details of the mechanical integration of the power coupler into the cryomodule. Details of thermal braids, connections, and other interfaces are discussed.
