摘　　要：利用理论分析和仿真模拟相结合的方法对带状电子注的产生进行了系统的研究,并提出了一种带状注电子枪的设计方法.首先通过理论分析,提出了一种计算带状注电子枪结构参数的迭代算法,即根据注电压、注电流、电子注注腰处半厚度、阴极半厚度和阴极宽度,计算出带状注电子枪的阴极柱面半径、阴阳极间距、阳极柱面半径和射程等主要参数;在此基础上,通过仿真模拟,为毫米波真空电子器件设计了一种带状注电子枪.Sheet-beam formation has been studied using the combination method of theory analysis and simulation verification.A design theory of the sheet-beam electron gun has been proposed.The beam voltage,the beam current,the half-thickness of beam at the waist position,the half-thickness of the cathode,and the width of the cathode are used to calculate the parameters of the sheet-beam electron gun such as the cathode cylindrical radius,the anode-cathode spacing,the anode cylindrical radius,and the throw.Then through simulation,the sheet-beam electron gun for millimeterwave vacuum election devices are set up based on the theoretical results.
