论文摘要
游离电子激光器（FELS）是在硬X射线方案中提供强烈，相干和明亮辐射的解决方案。由于FEL设施的壁插入效率较低，因此对于开发完整而准确的仿真工具以更好地优化FEL相互作用至关重要，而且非常有用。 FEL过程中涉及的高度复杂的动态是阻碍此问题开发一般仿真工具的主要障碍。 Mithra软件通过提供用于FEL流程的全波模拟平台来解决此问题。全波求解器采用基于Lorentz增强坐标系的细胞（FDTD/PIC）中有限差的时间域/粒子（FDTD/PIC）中的数值算法。开发的软件为分析FEL交互作用提供了合适的工具，而无需考虑任何常规近似值。此贡献是该软件第二版的完整手册，即Mithra 2.0，该软件在优化软件性能和删除代码中的几个错误后就发布了。
Free Electron Lasers (FELs) are a solution for providing intense, coherent and bright radiation in the hard X-ray regime. Due to the low wall-plug efficiency of FEL facilities, it is crucial and additionally very useful to develop complete and accurate simulation tools for better optimizing a FEL interaction. The highly sophisticated dynamics involved in a FEL process was the main obstacle hindering the development of general simulation tools for this problem. The software MITHRA tackles this problem by offering a platform for full-wave simulation of FEL process. The full-wave solver employs a numerical algorithm based on finite difference time domain/Particle in cell (FDTD/PIC) in a Lorentz boosted coordinate system. The developed software offers a suitable tool for the analysis of FEL interactions without considering any of the usual approximations. This contribution is the complete manual for the second version of this software, namely MITHRA 2.0, which is released after extensive efforts on optimizing the software performance and removal of several bugs in the code.
