摘要
以折叠波导作为为慢波结构进行研究分析,利用三维电磁仿真软件HFSS和CST,对0.14THz行波管模型进行了折叠波导慢波结构、电子光学系统和输入输出窗等的模拟设计,并完成了整管的PIC注波互作用的仿真计算与优化。进行了整管的焊接工艺设计和热测实验,研制出的样管在电压15.4kV、电流17.4mA下,脉冲工作输出最大功率为8.3 W,输出中心频率为140.8GHz,最大增益为28dB,-3dB带宽为2.9GHz。
The folded waveguide, the electron optical system, input and output windows of the 0.14 THz folded waveguide traveling-wave tubes were designed and simulated with the help of HFSS and CST. The beam wave interaction was also simula ted. Research on development of 0.14 THz TWTs was done, including fabrication and welding of the folded waveguide slow wave structure and hot test experiment. In the condition of voltage 15.4 kV, the maximum saturated output power was 8.3W and the output frequency was 140.8 GHz. The maximum gain was 28 dB and maximum power bandwidth was 2.9 GHz.
