Research Abstract

The purpose of this research is to realize high power (~ 10 W) radiation source in the terahertz range. Gyrotron is characterized by delivering high output power. In order to obtain high frequency radiation, the gyrotron is equipped with a 20 T superconducting magnet. The gyrotron operated in the magnetic field intensity of 19.3 T produced output radiation. The radiation is detected by a pyro-electric detector. The radiation is not blocked by attaching the high-pass filter to the detector. Cutoff frequency of the high-pass filter is lower than fundamental operation frequency of the gyrotron. The gyrotron output frequency for second harmonic operation is higher than 1 THz. The output power is intense enough to radiation source. The cavity and up-taper to ensure high mode purity output are manufactured and are installed in the gyrotron. High purity mode output will be efficiently converted into the Gaussian beam. This gyrotron is suitable for radiation source in the terahertz range.
