本文叙述一种有希望得到以接近百分之百的极高效率来产生特大功率的微波管新原理。该原理有可能导致粒子加速器、核聚变研究以及卫星太阳能电站提供数兆瓦功率微波管设计的焕然一新。一种低导流系数的电子注在圆周极化的模型中受到横向调制,这与偏转板上电压相位差为90°的阴极射线管中的电子注相类似。迴旋电子注与输出行波环形谐振器中的高频场相互作用,并通过环绕在谐振器外面的定向耦合器耦合至外部负载。对薄电子注来讲,理论上的转换效率是百分之百,而对于有一定尺寸的实际电子注来说,效率要低些。文中详细介绍了有关调制模型、电子注的离散以及所期望的效率。
This article describes a promising new principle for microwave tubes that generate extremely high power with extremely high efficiency approaching 100%. This principle is likely to lead to a new look at particle accelerators, nuclear fusion studies, and the design of several megawatts of microwave power at satellite solar farms. A low-conductivity electron injection is laterally modulated in a circularly polarized model, similar to the electron injection in a cathode ray tube with a 90 ° phase difference across the deflection plate. The cyclotron electron beam interacts with the high frequency field in the output traveling-wave ring resonator and is coupled to the external load by a directional coupler that surrounds the outside of the resonator. For thin electron injection, the theoretical conversion efficiency is 100%, and for a real size electronic injection, the efficiency is lower. The article details the modulation model, the discreteness of the electron injection, and the desired efficiency.
