Abstract

The gyrotron FU-VI, which can oscillate in the terahertz region has been developed. Tera-hertz operations with the second harmonic operation have been detected by a hot electron detector after a high-pass filter and/or a band-pass filter. The main magnetic field coil of the FU-VI is a pulse magnet coil protected by ice with alumina powder, and can generate the magnetic field 20 T or higher in the resonant cavity. One of the second harmonic operations has been confirmed experimentally at 1.010 THz due to TE_4,12 cavity mode at the magnetic field 19.1 T in the resonator.
