    Mitsubishi Heavy Industries' Normal Conducting/Superconducting Accelerating Cavities - Contributing to the Development of Highly-advanced Particle Accelerator Systems -

    Mitsubishi Heavy Industries
    Mechatronics Systems, Ltd.

    At the beginning of 2014, highly-advanced particle accelerator projects in Japan successively verified beam acceleration. One of the projects was the intensification of linac energy in Japan Proton Accelerator Research Complex (J-PARC). In this project, Annular-ring Coupled Structure (ACS) cavities with excellent axial symmetric properties of the Accelerating electric field were used as the accelerating cavity and started commercial operation of the world's first proton beam accelerator . The other project was the KEK-cERL (Compact Energy Recovery Linac) Project of the High Energy Accelerator Research Organization (KEK) in Tsukuba city. In this project, a superconducting accelerating cavity capable of continuous-wave operation in a high-acceleration electric field was used and the technological verification operation of a next-generation light source accelerator for the realization of high-quality beam recovering and reusing the accelerated electron beam energy was implemented. In both of the projects, Mitsubishi Heavy Industries, Ltd. (MHI) was in charge of the development and actual manufacturing of cavities, and realized a high-acceleration electric field higher than the customer request.
