摘要

通过参数仿真，优化了具有不同电压偏置的两个同轴控制电极的陀螺管行波放大器的尖端炮，目标是在220 GHz的中心工作频率下实现10 kW的输出功率。电子束的开与关是通过在电极上施加适当的偏置来控制的。在70 kV工作电压下，模拟出电流为1.5 a、节距系数为1.23的环形绕轴电子束。通过调节施加在控制电极上的不同偏置电压，音高因子扩展从5.0%提高到3.4%。

Design of a Cusp Gun With Two Control Electrodes Biased at Different Voltages

A cusp gun with two coaxial control electrodes biased at different voltages was optimized through parametric simulations for a gyrotron traveling-wave amplifier aiming to achieve an output power of 10 kW at a central operating frequency of 220 GHz. The on and off of the electron beam are controlled by applying an appropriate bias to the electrodes. An annular axis-encircling electron beam with a current of 1.5 A, a pitch factor of 1.23, was simulated when the gun was operated at 70 kV. The pitch-factor spread was improved from 5.0% to 3.4% by adjusting the different bias voltages applied to the control electrodes.
