A project to develop a coherent Teraherz (THz) light source has been progressed at Laboratory of Nuclear Science, Tohoku University. The coherent synchrotron light in the THz region is emitted from electron bunches with very short bunch less than 100 fs (rms) created by a thermionic RF gun and a sophisticated bunch compressor. The beam can circulate through the nearly complete isochronous ring for many turns, so that the average radiation power may be considerably enhanced. As an injector of this ring, we have developed an independently tunable cells (ITC) RF gun, which consists of two independent cavities to manipulate the longitudinal phase space. In order to generate short bunch with a significant bunch charge, a magnetic compressor is needed at downstream of ITC-RF gun. Two kinds of bunch compressor have been studied. This paper presents the isochronous THz ring design and describes ITC-RF gun, the magnetic bunch compressor and results of simulations. From simulation of the bunch compressor, we got a very short bunch length about 42 fs (rms).
