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.

本研究的目的是实现太赫兹范围内的高功率(~10W)辐射源。回旋管的特点是输出功率高。为了获得高频辐射，回旋管配备了20T超导磁体。工作在19.3T磁场强度下的回旋管产生了输出辐射。辐射由热释电探测器探测到。通过将高通过滤器连接到探测器上，辐射不会被阻挡。高通滤波器的截止频率低于回旋管的基波工作频率。二次谐波工作的回旋管输出频率高于1太赫兹。输出功率强到足以成为辐射源。制造腔和上锥度以确保高模式纯度输出，并将其安装在回旋管中。高纯模输出将被高效地转换为高斯光束。这种回旋管适用于太赫兹范围内的辐射源。
