MITHRA 2.0：自由电子激光的全波模拟工具
MITHRA 2.0: A Full-Wave Simulation Tool for Free Electron Lasers
摘要：
自由电子激光（FEL）是一种在硬X射线领域提供强、相干和明亮辐射的解决方案。由于自由电子激光设备的低壁插效率，这是至关重要的，另外非常有用的，以更好地优化自由电子激光相互作用，开发完整和准确的模拟工具。自由电子激光过程中涉及的高度复杂的动力学是阻碍开发通用模拟工具的主要障碍。MITHRA软件为自由电子激光过程的全波模拟提供了一个平台。全波求解器采用基于Lorentz提升坐标系的时域有限差分/粒子网格（FDTD/PIC）的数值算法。所开发的软件提供了一个合适的工具，自由电子激光相互作用的分析，而不考虑任何通常的近似。这份贡献是该软件第二版的完整手册，即MITHRA 2.0，它是在优化软件性能和删除代码中的几个错误的广泛努力后发布的。
英文摘要：
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.
