Research on 0.1THz Folded Waveguide Extended Interaction Oscillator Radiation Source

介绍了以折叠波导为慢波结构的太赫兹扩展互作用振荡器,并对其进行了基本理论分析,给出了色散方程和耦合阻抗。并利用三维PIC粒子模拟软件对设计的腔体进行了三维模拟计算。结果显示,在输入电子注电压为20.6kV,电流为0.12A时,可得到频率为0.1THz、347W的脉冲输出功率,互作用效率达到13.9%。

In this paper, a folded waveguide extended interaction oscillator (EIO) is introduced, followed by a analysis of the relevant fundamental theory. The EIO is designed and simulated with 3D PIC code. The results show a 347 kW peak power at O.lTHz, with an interaction efficiency of 13.9%, and the injection of an electron beam at 20.6kV and a current of 0.12A.
