摘要
对折叠波导慢波结构进行了研究,对其色散特性和耦合阻抗进行分析,并设计了输能窗和电子光学系统,在此基础上进行了粒子模拟的束波互作用计算。通过设计,对0.14 THz行波管进行了制管工艺的研究,包括慢波结构的加工和焊接等,完成了热测实验。在电压为16.3 kV,电子流通率为74%条件下,测试得到最大饱和输出功率3.1 W,输出频率140.08 GHz,增益27 dB,最大功率半带宽2.82 GHz。
The dispersion characteristic and coupling impedance of the Folded Waveguide Slow Wave Structure（FWSWS） are analyzed for 0.14 THz Traveling Wave Tube（TWT）. The power transmission window and the electron optical system are designed. The beam-wave interaction is simulated. Research on manufacturing process of 0.14 THz TWT is performed including fabrication and welding of the FWSWS and hot test experiment. Under the experiment conditions of electron transmission ratio 74% and voltage 16.3 kV, the maximum saturated output power is 3.1 W and the output frequency is 140.08 GHz. The maximum gain is 27 dB and maximum power half bandwidth is 2.82 GHz.
