Project Open Data (JSON)The dataset contains all input data and results of the MCPlas toolbox presented in the publication [https://doi.org/10.48550/arXiv.2512.18091]. The MCPlas toolbox represents a collection of MATLAB functions for the automated generation of an equation-based fluid-Poisson model for non-thermal plasmas in the multiphysics simulation software COMSOL. Following the development of the new generation of the LXCat platform, all input data are prepared in a structured and interoperable JSON format and can be supplied and validated using existing JSON schemas. The toolbox includes fully transparent, editable MATLAB source code and offers an advanced description of electron transport in addition to commonly used approaches in the plasma modelling community. It supports one-dimensional and two-dimensional modelling geometries employing Cartesian, polar and cylindrical coordinate systems. MCPlas is tested on two reference cases: DC- and RF-driven low-pressure glow discharges in argon.

| Plasma Source Application | |
| Plasma Source Specification | |
| Plasma Source Properties | All modelling studies were performed for two test cases, namely DC and RF low-pressure glow discharges in argon using a plane-parallel electrode configuration. DC case: A contant DC voltage of 350 V is applied at the powered electrode. RF case: a sinusoidal voltage with an amplitude of 350 V and a frequency of 13.56 MHz is used. The gap distance is set to 1 cm. |
| Plasma Source Procedure | The DC and RF discharges a simulated until reaching a quasi-stationary state. |
| Plasma Medium Name | |
| Plasma Medium Properties | Pressure: 1 Torr |
| Plasma Medium Procedure | Gas temperature and pressure are kept constant throughout the simulations. |
| Plasma Diagnostics Name | |
| Plasma Diagnostics Properties | The plasma description provided by MCPlas is based on a fluid-Poisson model comprising balance equations for the particle number densities of species, a balance equation for the energy density of electrons and the Poisson equation for the self-consistent determination of the electric potential and electric field. The particle fluxes and the electron energy flux are described in different drift-diffusion approximations, where DDAn and DDA5/3 are used for electrons. |
| Plasma Diagnostics Procedure | The model generated by MCPlas is compared with the COMSOL Plasma Module (CPM). To demonstrate the ability of MCPlas to manage different reaction kinetic models (RKMs), a 4-species and a 23-species RKM are used to model the DC and RF argon plasmas. Furthermore, the reusability of the JSON schema-based input data defining the RKM is demonstrated by a comparison study involving the plasma modelling toolboxes PLASIMO and FEDM. |
