A C-band Test Platform for the Development of RF Photo Cathode and High Gradient Accelerating Structures

Abstract

In order to promote the studies of low emittance RF photo cathode and high gradient accelerating structures, a C-band test platform has been initialized since late 2021. In this paper, an overview of the present status and future plans of this platform is given. A 3.6-cell C-band RF photo cathode has been manufactured and now is under test. In addition, studies such as the design for a C-band RF traveling-wave accelerating structure and the design of a C-band high gradient parallel-coupled accelerating structure utilizing short pulse are introduced.
