| Research Abstract |
Production method for short-pulse electron beam with its bunch length around 100 fs or less has been mostly established. The method employs the velocity bunching mechanism in a traveling-wave accelerating structure and an original electron gun. The gun is composed of two independent cavity cells so as to manipulate and optimize the longitudinal phase space electron distribution for the velocity bunching scheme. The accelerator system was completed, after which the electron beam was successfully accelerated up to 50 MeV, thereby it might be possible to produce coherent terahertz (THz) radiation using bending magnets and/or undulators. It can be concluded that a light source accelerator facility for THz science, in which radiation safety program was accurately approved by the national regulation, is established.
