DEVELOPMENT OF SUPERCONDUCTING SPOKE CAVITY FOR ELECTRON ACCELERATORS

A 325MHz superconducting spoke cavity for the electron acceleration is under development to realize a compact industrial-use X-ray source with the laser-Compton scattering. Optimum designs of the spoke cavity have been searched by using the genetic algorithm, and multipactor simulations are currently in progress to finalize the detailed design. In parallel to the design-optimization eorts, studies toward fabrication processes are also being carried out. In this paper, progresses made so far and a current situation are briefly reviewed.
