摘要 通过对电子束在微波场中运动情况的分析,建立了微波场与电子束相互作用的单电子运动学模型,得到了电子束横波的表达式;从理论角度分析了电子束横波与微波场进行能量交换的机理,导出了回旋波、同步波与微波场进行能量交换的表达式,得出能量交换的效率与电子束流大小、外加场频率、回旋频率以及横向位移有关,为设计制作高效率的微波场能量交换器件提供了理论依据. The energy conversion efficiency from microwave energy to kinetic energy of electron beam is very important in high power transmission by microwave. This paper establishes a single electron kinematics model of interaction between microwave field and transverse eigenmodes of electron beam through analyzing the motion of electron beam. Energy exchange expressions of cyclotron waves and synchronous waves are derived. Analysis the mechanism of energy conversion between microwave field and electron beam, the efficiency of energy exchange is related to electron beam, microwave frequency, cyclotron frequency and transverse deviation of electron beam. The study is the theoretical foundation of high efficiency energy exchange device.
