Research Abstract

In this study, I investigated structure of an emitter and electron beam condition for Cherenkov EUV radiation. I found Scandium is the most efficient emitter in water-window region. In order to enhance the efficiency of Cherenkov EUV radiation, new emitter with periodic structures is proposed. Slope temperature and period of emitter structure are optimized, and intensity of Cherenkov EUV radiation is calculated. These results show the road map for efficient Cherenkov EUV radiation.
