Outline of Final Research Achievements

An accelerator based light sources for intense coherent THz light requires the electron bunch length shorter than a few hundred femtosecond. In order to improve the performance of accelerator based light sources, it is indispensable to measure the electron distribution in longitudinal phase space for understanding the beam dynamics at the bunching section. In this study, the longitudinal phase space measurement system by Cherenkov light observation applying velocity dependence of opening angle has been developed. This developed system is composed of a special optical system and a Cherenkov radiator. The designed special optical system has sufficient resolution to measure the longitudinal phase space. The beam test of the Cherenkov radiator was performed at beam diagnosis section of t-ACTS. In addition, the clear Cherenkov ring was observed. This measurement system is a promising system for innovative beam diagnosis technology.
