Митра 2.0: Как моделировать лазер на свободных электронах

MITHRA 2.0: A Full-Wave Simulation Tool for Free Electron Lasers:
Arya Fallahi
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.
