# Betaboltz: a Monte-Carlo simulation tool for gas scattering processes

## TL;DR

Betaboltz is an open-source C++17 simulation tool for modeling electron and ion transport in gas mixtures under electric and magnetic fields, validated against existing drift velocity data.

## Contribution

It introduces a flexible, open-source Monte Carlo simulation framework for gas scattering processes with user-defined mixtures and external fields, integrated with LXCat cross-section data.

## Key findings

- Validated against drift velocity tables with acceptable accuracy.
- Supports user-defined gas mixtures and external fields.
- Open-source and easily integrable as a shared library.

## Abstract

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.
