论文摘要
我们提出了一种分析方法，用于计算由两际电子束支撑的太空波和电场的波数和电场，由两流电子束支撑，由固体内部圆柱形流和同轴外环流组成，都包含在圆柱金属隧道中。我们将RAMO开发的分析模型扩展到了两个流的分析模型。该方法解释了两条流与梁孔壁的存在之间的相互作用；它可用于模拟与两流不稳定性相关的复杂波数和真空电子放大器和其他真空电子设备中的血浆频率降低效应。
We present an analytical method to compute the wavenumbers and electric fields of the space-charge-wave eigenmodes supported by a two-stream electron beam, consisting of a solid inner cylindrical stream and a coaxial outer annular stream, both contained within a cylindrical metallic tunnel.We extend the analytical model developed by Ramo to the case of two streams. The method accounts for the interaction between the two streams with the presence of the beam-tunnel wall; it can be used to model the complex wavenumbers associated with the two-stream instability and the plasma frequency reduction effects in vacuum electronic amplifiers and other vacuum electronic devices.
