In this work, we present a 0.46 THz gyrotron operating at 9th harmonic based on axis encircling electron beam. With the help of CST-PIC (computer simulation technology-particle in cell), the mode competition of the large orbit gyrotron (LOG) is discussed. A 9th harmonic terahertz gyrotron with large orbit beams is novelty optimized at 0.46 THz, achieving a peak output power of 8.05 kW when the electron beam voltage is 250 kV and the current is 4.5 A, which provides key technical support for applied biomedical applications.

摘要

In this work, we present a 0.46 THz gyrotron operating at 9th harmonic based on axis encircling electron beam. With the help of CST-PIC (computer simulation technology-particle in cell), the mode competition of the large orbit gyrotron (LOG) is discussed. A 9th harmonic terahertz gyrotron with large orbit beams is novelty optimized at 0.46 THz, achieving a peak output power of 8.05 kW when the electron beam voltage is 250 kV and the current is 4.5 A, which provides key technical support for applied biomedical applications.
