超高次谐波太赫兹大回旋振荡管研究
Research on Ultra-high Harmonic Terahertz Gyrotrons with Large Orbit Beams
摘要
Abstract
The gyrotron with large orbit beams has good mode selection characteristics,which can ef-fectively suppress the mode competition of terahertz gyrotron oscillators.The characteristics enables the terahertz gyrotron oscillators to operate stably in high harmonic high order mode,greatly reducing the re-quirement of the applied magnetic field and increasing the size of high-frequency interaction circuits,im-proving power capacity,and providing the possibility of achieving high-power and high-frequency terahertz wave radiation.The theory of the beam wave interaction in ultra-high order harmonic gyrotron with large orbit beams is studied.With the help of three-dimensional particle simulation software,the physical process and mode competition of the beam wave interaction in ultra-high order terahertz gyrotron with large orbit beams are discussed.A ninth harmonic terahertz gyrotron with large orbit beams are optimized at the frequency of 464 GHz,achieving a peak output power of 7.5 kW at an electron beam voltage of 250 kV and a current of 4.5 A,which provides key technical support for applied biomedical applications.关键词
