Ultrashort electron beams are essential for light sources and time-resolved measurements. Electron beams can emit terahertz (THz) pulses using coherent transition radiation (CTR). Simultaneous measurement of CTR from 35 MeV electron beam using an interferometer and photoconductive antenna will be reported. The combination of techniques for THz spectroscopy will be applied to the measurement of CTR in time- and frequency-domain.
