Terahertz-Wave Beamline Using Coherent Edge Radiation at Nihon University

A terahertz (THz) beamline in which intense broad-band THz waves are available has been developed at Laboratory for Electron Beam Research and Application of Nihon University. A coherent edge radiation beam generated at a downstream bending magnet in the parametric X-ray straight section is transported to an experimental room by the THz beamline, and THz waves with the energy of 0.2 mJ per 4.5 ms macropulse can be used for spectroscopy and/or imaging measurements in the frequency region of 0.3−3 THz. It is expected that this THz beamline, in which anyone can use high-intensity THz waves, will contribute to developments of THz science.
