摘要
提出并研究了一种具有结构紧凑、散热性好、输出功率大等特点的新型扩展互作用结构——径向扩展互作用振荡器(EIO),并推导了小信号理论.利用电磁仿真软件分析了径向EIO高频结构中的谐振特性与场分布,并采用三维粒子模拟软件开展了注波互作用研究.研究结果表明在工作电压为5 k V,电流为8.48 A时,所设计的径向EIO输出功率达到2.6 k W,热腔工作频率为30.011 GHz,效率为6.1%.
A radial extended interaction oscillator has been presented in this paper. This newstructure has characteristics such as compact structure,good heat dissipation and high output power. The characteristics trends of 4-cavities radial EIO has been determined through the analysis of a single coaxial resonator gap. And the operating frequency and voltage is more accurately tested by simulation of electromagnetic simulation software and small signal theory analysis. Since the electron emission surface of the electron gun of radial EIO is much larger than that of conventional EIO,so in the case of small current density,a large current can be obtained. When the voltage is 5k V and the current is 8. 48 A,the PIC simulation shows that the radial EIO could generate 2. 6 k W in 30. 011 GHz.
