Muonic X-ray elemental analysis is a non-destructive technique that can be used to study the elemental composition of a whole sample: from micrometres down to centimetres below its surface. Some of the current applications of this technique are to determine the composition of ancient archaeological samples, which cannot sustain any type of physical damage, and also to study meteorites, biological samples and functional materials. This project aims to develop a robust method to model the muonic X-ray spectra quantitatively. This can be achieved by numerically solving the Dirac equation, that describes all the muon transitions occurring in the experiment. The theoretical and methodological developments will be implemented in MuDirac, which is a modern, open-source, sustainable software tool that is being used to aid in muonic X-ray elemental analysis.

μ子X射线元素分析是一种非破坏性技术，可用于研究整个样品的元素组成：从表面以下几微米到几厘米。这项技术目前的一些应用是确定古代考古样品的组成，这些样品不能承受任何类型的物理损坏，以及研究陨石，生物样品和功能材料。本项目旨在开发一种可靠的方法来定量模拟μ子X射线光谱。这可以通过数值求解狄拉克方程来实现，狄拉克方程描述了实验中发生的所有μ子跃迁。理论和方法的发展将在MuDirac中实施，MuDirac是一种现代，开源，可持续的软件工具，用于辅助μ子X射线元素分析。
