Betaboltz: A Monte-Carlo simulation tool for gas scattering processes

We present an open-source code for the simulation of electron and ion transport for user-defined gas mixtures with static uniform electric and magnetic fields. The program provides microscopic interaction simulation and is interfaced with cross-section tables published by LXCat[1]. The framework was validated against drift velocity tables available in literature obtaining an acceptable match for atomic and non-polar molecular gases with spherical symmetry. The code is written in C++17 and is available as a shared library for easy integration into other simulation applications.

本报告呈现了一款开源代码，旨在模拟用户自定义气体混合物在静态均匀的电场和磁场条件下的电子与离子传输。该程序提供微观相互作用模拟，并与由LXCat[1]发布的截面数据表相接口。框架通过与文献中可获得的漂移速度表进行验证，对于具有球对称性的原子和非极性分子气体，实现了可接受的匹配度。代码采用C++17编写，并以共享库的形式提供，便于集成至其他仿真应用中。
