A project of pre-bunched FEL as a Terahertz (THz) light source using short electron bunches less than 100 femtosecond has been progressed at Laboratory of Nuclear Science, Tohoku University. We expect FEL with shorter electron bunch generates different characteristics of light pulse from conventional FELs with long electron bunch. By choosing appropriate initial electron phases (bunch length is less than wavelength of FEL), the FEL gain will be higher. We have developed a numerical simulation code by solving 1-D equations. We report on time structures of FEL field and trajectory of electron in separatrix.
