研究了一种回旋速调管放大器时域非线性理论模型.该模型由广义电报方程来表示回旋速调管内的电磁场,采用引导中心近似的电子运动方程来推动粒子,由粒子更新得到的电流密度为源激励电磁场.基于上述理论模型,从回旋速调管电子注横向速度满足高斯分布出发,建立了速度分散的分布模型,编写了相应的时域非线性注波互作用模拟程序,对回旋速调管放大器的注波互作用进行了深入的分析和研究,并应用粒子模拟软件与自洽非线性模拟程序进行对比验证,两者结果基本一致.
A time-domain non-linear theoretical model of gyroklystron amplifier is studied. The model uses the generalized telegraph equation to represent the electromagnetic field in the gyroklystron, and uses the approximate electronic motion equation of the guidance center to promote the particle. The current density As the source excitation electromagnetic field.Based on the above theoretical model, starting from the gyroscope klystron electronic transverse velocity to meet the Gaussian distribution, the establishment of a velocity dispersion of the distribution model, the preparation of the corresponding nonlinear time-domain wave-wave interaction simulation program, the gyroscopic velocity The wave-tube interaction of the tube-amplifier is analyzed and researched. The particle simulation software and the self-consistent nonlinear simulation program are used to verify the results. The results of the two are basically the same.
