| 摘 要： | 研究了强流相对论电子束在任意截面波导空间电荷极限电流的二维解析计算;具体给出了平板波导、矩形波导和圆波导结构中空间电荷极限电流的解析表达式;并用格林函数法求得矩形谐振腔及圆柱谐振腔中空间电荷极限电流的解析解.上述矩形波导和矩形腔中 I_(SCL)的分析未见文献发表,而圆柱波导的结果同已有的数值分析良好吻合.

| Abstract: | Two-dimensional analytical calculation of the space-charge-limit current of in-tense relativistic eiectron beam in arbitrary cross-sectional waveguide is studied.The analyticalexpressions of the space-charge-limit current in the plane-plate waveguide,the rectangularwaveguide and the circular waveguide are derived in detail.The analytical solutions of the space-charge-limit current in the rectangular resonator and the circular resonator are found by theGreen's function method. |
