Numerical data from: Fully-implicit Particle-in-Cell model of a Magnetic Nozzle with electromagnetic power deposition - Authors: Mario Merino, Juan Martín, Pedro Jiménez, Luis Chacón- Contact email: [e-mail], [e-mail]- Date: 2026-06-12 - Keywords: Plasma Physics, ECR, collisionless, charge-energy conserving PIC, wave heating- Version 1.0.0- Digital Object Identifier (DOI): 10.5281/zenodo.20714867- License: This dataset is made available under the [Open Data Commons Attribution License](http://opendatacommons.org/licenses/by/1.0/) Abstract This dataset contains simulation results of the plasma properties in the magnetic nozzle of an electrodeless plasma thruster using a fully implicit charge-energy conserving Particle In Cell code. Various simulations with differing electromagnetic wave power values leaking into the magnetic nozzle are included. Dataset description The dataset comprises of five different wave power cases: no power -case O-, 2 W/cm^2 -case L-, 10 W/cm^2 -case M-, 50 W/cm^2 -case H- and 100 W/cm^2 -case X-. It also contains the data of a convergence study applied on the reference case M: doubling the time step -case M(dt)-, halving the number of particles -case M(Np)-, halving the number of cells -M(Ng)- and an extension of the domain up to a 35% -M(ext)-. All the results are in steady state.

The file contains the following fields: Ba: the magnetic field aplied [G]. z: the z coordinates of the domain [cm]. f: derivative of transformation function to the computational mesh. h: normalized radius of the magnetic tube. phi: electric potential [V]. A / alpha: magnetic potential expressed as module and argument (gyrophase) [Gcm] / [deg]. ne / ni: particle density of electrons and ions [m^-3]. u (z/p)(e/i): parallel and perpendicular velocity for electrons and ions [m/s]. T (z/p)(e/i): parallel and perpendicular temperatures for electrons and ions [eV]. q (z/p)(e/i): parallel and perpendicular heat for electrons and ions [W/cm^2]. The varying power cases have two additional files for the phase space histograms of the electron velocity distribution function for figures 7 and 8 of the article. The data for the phase space histograms is averaged over the last 3000 time steps. These files have the suffix PS_fig_7 and PS_fig_8 attached to the case name, respectively. These files are stored in a .jld2 format, that adheres to the HDF5 format specification, making it compatible with HDF5 tooling and H5 libraries in other languages. The PS_fig_7 files contain the electron velocity distribution function histograms in terms of the phase spaces of the z coordinate and of the parallel velocity, the magnetic moment and the gyrophase. They contain the following fields: z: the z coordinates of the domain, they work as the x coordinate for all histograms. vz, μ, α: parallel velocity, magnetic moment and gyrophase, each work as the y coordinate for each histogramm. log10PS_z_(vz, μ, α): base 10 logarithm of the electron velocity distribution function histograms in terms of the phase space z/vz, z/μ and z/α The PS_fig_8 files contain the electron velocity distribution function histograms in terms of the phase space of the parallel and perpendicular velocity in four characteristic sections of the domain: upstream (U), the throat (T), the resonance (R) and downstream (D). They contain the following fields: vz: parallel velocity, works as the x coordinate of the histogram. vp: perpendicular velocity, works as the y coordinate of the histogram. log10PS_vz_vp_(U, T, R, D): base 10 logarithm of the electron velocity distribution function histograms in terms of vz/vp for the chracteristic regions Citation Any works using this dataset in any form shall cite it as follows.
