Mitsubishi Heavy Industries (MHI) has developed the manufacturing process of superconducting cavities for a long time. In this paper, recent progress of our work will be reported.
Mitsubishi Heavy Industries, Ltd. (MHI) manufactured the Superconducting Accelerator Cavity Module of the Injector and the Main Linac of the c-ERL facility being constructed by the High Energy Accelerator Research Organization (KEK). This report provides status of the development.
We have supplied some 1.3 GHz superconducting RF cavities for STF project and cERL project for few years. Recently, we have manufactured STF phase 2.0 cavities (MHI-#12 to #22). Some of them achieved ILC specification in vertical test at KEK. We have also manufactured three sets of 2-cell cavities for injector linac modules of cERL and two sets of 9-cell cavities for main linac modules of cERL. These cavities were governed to high pressure gas safety law in Japan. We report recent activities of superconducting RF cavity at MHI in this paper.
