Description

The introduction of thin film structures into superconducting cavities is theoretically predicted to improve performance, and experimental verification is now required. In this study, we are developing a relatively small and easy-to-handle niobium-made 3 GHz single-cell cavity to verify the effects of introducing thin film structures. We performed vertical measurements on the 3 GHz single-cell cavity after applying standard BCP and EP treatments, and obtained baseline data prior to the introduction of thin film structures. In this presentation, we report on the longitudinal measurement setup and results for the 3 GHz cavity, as well as our future research plans.
