    Abstract

    We have manufactured the back-illuminated superconducting photocathode for the FEL with high pulse repetition. The novelty of this photocathode is adopting the transparent superconducting thin film LiTi2O4 as a substrate. The reason for using LTO is to reflect RF by using feature of penetration depth of superconductor, which is defined from London equation. This feature protects optical components from RF damage. These are able to make a high quality beam which is a low energy spread and a low space spread. This paper presents a summary of the experiment, a brief overview of our activities and outlines future plans.
