Study of the Sheet Beam Transmission Based on 2D Macroparticle Model

摘要

摘要: 带状电子注具有非轴对称性和大宽高比的特性，非常适合应用于高功率微波与毫米波真空电子器件电子注形成。该文针对带状电子注的这种特性，建立了2维窄带宏粒子模型，编写了静电磁约束下带状电子注传输过程的分析计算程序，讨论了无外加高频场时带状电子注在均匀磁场和周期会切磁场聚焦情况下的传输过程，数值计算结果与单粒子模型及3维PIC软件模拟结果进行了比较，结果表明，该文编写程序的计算结果与3维PIC软件的有很好的一致性，且计算速率有大幅度提升。

Abstract: The sheet beam with a large width-high ratio is nonaxisymmetrical, which is very suitable to the formation of the electron beam in high power microwave and millimeter wave vacuum devices. In this paper, a 2D macroparticle model is proposed for developing a program to study the sheet beam transmission. The transmission of the sheet beam in an uniform magnetic field and Periodic Cusped Magnetic (PCM) field is discussed, and the calculation results are compared with the single particle model and 3D PIC software, which show good agreement with 3D PIC softwares and the computation time is greatly reduced.
