摘　　要：提出并研究了一个基于双腔耦合的高功率微波振荡器。该结构由两个腔和一个漂移管构成,两腔之间的耦合对于在给定条件下振荡的产生有重要的影响。该结构在运行时相较于一个分布式行波器件更类似于一个速调管。结果表明,该振荡器有更高的效率且无模式竞争。在自适应理论的基础上研究了大信号物理过程,引入了互作用因子k研究电子束和该结构之间的互作用程度,并设计了一个700 keV、10 kA的电子束驱动的S波段双腔振荡器。A structure of a high power microwave oscillator based on the couple between two cavities is proposed and studied.The structure composes of two cavities and a drifting tube.The couple between two cavities is important for the oscillation to occur under the controlled condition.The structure acts more like a klystron than a distributed traveling wave device.As a result,the oscillator has higher efficiency and its working mode is controlled without mode-competition.The large signal physic process is studied based on the self-consistent theory and the interaction factor k is introduced to study interactions between the beam and the structure.Finally,a conceptual design of a S-band bitron driven by a 700 keV,10 kA electron beam has been designed.
