Abstract :
A femto-second THz radiation facility, which uses an accelerator-based THz radiation source, is under commissioning at the Pohang Accelerator Laboratory. After the successful commissioning of a 60-MeV electron linear accelerator, the generation of THz radiation using CTR (coherent transition radiation) was carried out to get the measured THz intensity of 0.75 muJ/pulse, which is coherent from that but quite smaller than the target intensity.
