Abstract

We demonstrate the possibility of generating a periodic sequence of ultrashort electromagnetic microwave pulses in a scheme with two parallel coaxial electron beams formed by a common cathode and transported via common vacuum channel. The external cylindrical tubular beam ensures the amplification of radiation during rectilinear propagation along periodic slow-wave system, while the internal (paraxial) beam accounts for the nonlinear cyclotron-resonance absorption.

具有两个平行辐射和吸收电子束的方案中超短电磁脉冲周期序列的产生

摘要

我们证明了在由公共阴极形成并通过公共真空通道传输的两个平行同轴电子束的方案中，产生超短电磁微波脉冲周期序列的可能性。外部圆柱形管状束确保沿周期性慢波系统直线传播期间辐射的放大，而内部（近轴）束则是非线性回旋加速器共振吸收的原因。
