Power couplers are critically important components in all superconducting accelerators. Power couplers provide the vacuum and thermal interface between the superconducting cavity and the room temperature waveguide components and transmit microwaves generated by the high power klystron or IOT. Power couplers must be extraordinarily clean and reliable. CPI power couplers are manufactured to our customer?s specifications using processes which are standard to the electron device industry as well as processes which have been developed specifically for power couplers. We have developed the capability of electroplating high-RRR copper. Our high-RRR copper plating has been qualified by Cornell and DESY. We have developed the capability of applying TiN coatings to ceramic windows for multipactor suppression. Using these processes, CPI has manufactured over 50 power couplers of various designs with an additional 50 power couplers to be built this year. Our talk will focus on power couplers for the ILC. In particular, we will discuss some of the challenges to be faced during the manufacture of tens of thousands of power couplers for the ILC.
