【摘要】 采用电磁仿真软件对C波段多注速调管的输入腔、输出腔及中间腔的高频特性进行了冷腔分析。采用CHIPIC软件对高频互作用区进行了整体建模。为得到稳定且较高的输出功率,对电子束,输入功率及输出耦合结构等参数进行研究分析。通过对结果的分析,模拟整个高频结构的工作情况,在电子束电压28 kV,总电流为14.96 A的条件下,得到了功率为225 kW的峰值功率,效率为50%。更多还原

【Abstract】 The input,output and idler cavities of C-band multi-beam klystron were analyzed with the electromagnetic simulation software. The overall modeling of the high-frequency interaction area was achieved by means of CHIPIC software. To get the stable and high output power,the parameters,such as electron beam,input power and output coupling structure,were researched and analysed. Through the analysis of the results and simulation of the entire structure,the multi-beam klystron can produce the peak output power of 225 kW with efficiency of 50% in the case of electron beam voltage of 28 kV and total beam current of 14.96 A.更多还原
