摘要
文中首先阐述了半无限长阴极杆电流对径向电子束传输的影响,通过理论分析得到了径向同轴二极管内的磁场分布及单个电子偏移幅值的解析表达式;接下来分析了有限长阴极杆电流产生的角向磁场空间分布规律,并与半无限长阴极杆电流产生的磁场强度进行了对比;最后对有限长阴极杆电流下非浸没式径向电子束的传输过程进行了研究,建立了双端馈入电流模型并对其进行了误差分析,仿真得到了阴极杆电流长度对非浸没式径向电子束传输的影响规律。
the effect of semi-infinite cathode stick current on radial beam transmission is presented. By theoretically analysis, the distribution of azimuthal magnetic field in coaxial foilless diode and analytical expression of beam deviation is obtaine d. Then the magnetic field distribution laws of finite cathode stick current is studied and compared with semi-infinite condition. At last, the radial beam transmission process under non-immersed focusing magnetic field is investigated. We establish and analyze errors of current model with two ports feed. The characteristic of stick current length on radial beam transmission is achieved by PIC simulation.
