摘要

摘要: 該文利用回旋管注-波模式耦合理論，提出了返波振蕩-速調(diào)群聚-行波放大復合互作用回旋管工作原理。理論分析表明，Ka波段二次諧波連續(xù)磁調(diào)諧復合互作用回旋管的工作效率高達40%，磁調(diào)諧帶寬為10%。利用該復合互作用工作原理，回旋管振蕩器可實現(xiàn)毫米波電磁輻射源的高效率、高功率輸出及寬頻帶連續(xù)磁調(diào)諧。

Abstract: Based on the beam-wave mode-coupling theory, a principle of gyrotron device utilizing a hybrid interaction scheme of Backward-Wave Oscillator, Klystron Ballistic-Bunching and Traveling-Wave Tube (Gyro-BWO-KBB-TWT) is presented in this paper. Theoretical analysis of a Ka-band second harmonic tunable gyro-BWO-KBB-TWT indicates that the device efficiency of 40% and magnetic tuning bandwidth of 10% are achieved. A gyrotron oscillator employing the hybrid interaction scheme can realize highly efficient, high-power output and broadband continuous magnetic tuning in millimeter wave band.
