Abstract

We have been developing an Energy-Chirping-Cell attached RF electron gun (ECC-rf gun) for generating ultrashort electron bunches. ECC-rf gun has extra cell at the end of gun cavity in order to chirp the bunch energy. Such a bunch can be compressed by the velocity difference though the drift space. We have already installed it to our accelerator system and successfully observed a coherent synchrotron/transition radiation at 0.3 THz. It is clear that the bunch length was short enough to generate 0.3 THz, which corresponds to less than 500 fs bunch length was achieved if we assume the gaussian shape. In this conference, the principle of ECC-rf gun, the recent results of bunch length measurement and future prospective will be presented.
