レーザーコンプトン散乱を用いた小型で産業利用可能なX線源を実現するため、電子加速器用の325MHz超伝導スポーク空洞の開発を行っている。空洞形状の最適化は遺伝的アルゴリズムを用いて行っており、詳細設計を行うためにマルチパクターの計算を現在行っている。さらに製作に向けての検討も行っているので、それらについて発表を行う。

A 325 MHz 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 efforts, studies toward fabrication processes are also being carried out. In this paper, progresses made so far and a current situation are briefly reviewed.
