论文摘要
为了计算在6D相位空间中空间电荷主导的光束的非线性传输，已经开发了计算机代码包Leads-V5（线性和静电加速器动力学模拟）。这些代码计算由静电和磁聚焦透镜，离子分析仪，多物和RF加速结构组成的光束传输系统中的粒子运动。通过LIE代数方法分析外部电/磁场的非线性力，并通过细胞（PIC）方案中的粒子获得空间电荷力。在代码中，可以选择均匀和高斯粒子分布以随机生成粒子初始坐标。提供了优化过程，以使光束光学器件设计合理且快速。提供了图形显示计算结果的显示。
To calculate nonlinear transport of space charge dominated beam in 6D phase spaces, a computer code package LEADS-v5 (Linear and Electrostatic Accelerator Dynamics Simulations) has been developed. The codes calculate particle motions in the beam transport systems consisting of electrostatic and magnetic focusing lenses, ion analyzers, multipoles and RF accelerating structures. The nonlinear forces of external electric/magnetic fields are analyzed by the Lie algebraic method, and the space charge forces are obtained by the particle in cell (PIC) scheme. In the codes, Uniform and Gaussian particle distributions can be chosen to generate randomly the particle initial coordinates. The optimization procedures are provided to make the beam optics designs reasonable and fast. Graphically displays of calculated results are provided.
