【摘要】 本文利用三维PIC粒子模拟软件,对S波段扩展互作用速调管作了全三维的设计和优化,采用参差调谐、对腔和双间隙扩展互作用谐振腔来实现高增益和宽频带,对整管进行了设计和粒子模拟仿真,在工作电压65k V,电子注电流40A,工作中心频率为F₀的条件下,得到了峰值功率800kW,3d B带宽315MHz,效率为30.8%,饱和增益为42.8d B,粒子模拟与实验结果十分吻合。更多还原

【Abstract】 In this paper, development and research of S-band exended interaction klystron is presented with three-dimensional particle-in-cell(PIC) code.Extended interaction technologies are widely adopted in uneven cavities tuning, cavities loaded,dual cavities and two gaps extended interaction cavities,the klystron are all designed and optimized,the klys tron is driven by a 65 k V,40 A pencil beam,the output peak power of 800 k W is achieved,corresponding to the gain of 42.8d B,the efficiency of 30.8%,and the 3-d B bandwidth of 315 MHz at the centeral frequency F0,the experiment is accordable with particle simulation.更多还原
