| Outline of Final Research Achievements |
Development of terahertz (THz) wave source has been underway at Nihon University. The THz wave transport lines has been constructed on the same axis as the X-ray and FEL beam line. The average intensity of the THz coherent transition radiation (CTR) wave obtained at the output port in the accelerator room has been 1 mJ/macro-pulse (pulse width 4.5 us). The superposition transport system of the THz waves to the X-ray beam-line was installed in a multi-purpose vacuum chamber. Additionally, the energy of the coherent edge radiation (CER) as high as 0.2 mJ/macro-pulse were achieved with the experimental room. Although an optical system using a vacuum chamber is necessary, if the influence due to the absorption of water vapor is ignored, it is expected that the intensity of the THz wave would up to several-mJ as the electron beam power output increases. These THz waves has been used for user experiments for the imaging in addition to measurement of the spectrum.
