Python scripts for input and post-processing of fuzz sputtering TRI3DYN simulations

The influence of a fuzzy surface on the physical sputtering of Mo in He plasmas has been studied with hyperspectral imaging (HSI) measurements and simulations that couple the TRI3DYN code with an impurity transport code. The 2D profiles of the Mo I line emission intensity from HSI images reveal that the sputtering yield, Y, is reduced to ~40% of the smooth-surface value due to the presence of a fuzz layer, while the angular distribution of the sputtered Mo atoms might not change significantly. The simulations reproduce the Y reduction successfully, but indicate that fuzz causes an increase in the small-angle distribution of sputtered atoms. However, the increase is too small to produce an observable change in the Mo I emission profiles. A simple analytical model that assumes a single collision mean free path for a fuzz layer and considers only the primary sputtering events qualitatively reproduces the Y reduction and the small-angle distribution enhancement, explaining the geometrical e..., These are not the raw data of our results, but the Python scripts that can be used to reproduce the simulation results in our work.

## Introduction

This dataset contains the Python scripts required to reproduce the simulation results shown in \"Hyperspectral Imaging and TRI3DYN Simulation Study of Physical Sputtering from a Fuzzy Surface\", which was submitted to Nuclear Materials and Energy in late 2023.

The core simulation code used in this work was [TRI3DYN](https://www.hzdr.de/db/Cms?pOid=64858&pNid=2689&pLang=en), which unfortunately cannot be given here. Users interested in reproducing our simulation results should try to contact Prof. Dr. Wolfhard Möller () to get access to TRI3DYN by themselves. In this work, TRI3DYN was used to simulate the physical sputtering of Mo atoms on a fuzzy surface. Afterwards, a simple Monte-Carlo impurity transport code given in this dataset was used to simulate the 2D spatial profiles of Mo I line emission intensity, which were then compared with the experimental results.
