| Outline of Final Research Achievements |
THz Coherent Undulator Radiations (THz-CUR), which is a quasi-monochromatic intense THz radiation, were generated by injecting a short bunch electron beam generated from photocathode RF gun with a bunch compression chicane. Experiments to investigate the basic parameters of the THz-CUR were carried out. As the results, the frequency tunable range and the maximum micro-pulse energy of the THz-CUR was determined as 0.17-0.65 THz and 1 micro-J (at 0.17 THz), respectively. Moreover, the intensity saturation was observed when the amount of charge in an electron bunch was increased higher than 80 pC. The intensity saturation gave us information of the performance limitation of this THz-CUR source.
