Simulations of magnetized Spherical Langmuir probes

Dataset containing Particle-in-Cell simulations of Langmuir probes in magnetized plasma decribed in the paper "Spherical Langmuir probes in magnetized plasma. A model based on Particle-in-Cell simulations". The simulations are done for plasma parameters representative of the lower E-region ionosphere, with probe biases in the electron saturation regime.

Each simulation has its own folder denoting the magnetic field strength |B| in Tesla, and probe bias electric potential in Voltage. The folder naming convention uses three digits for numerical values, where the last digit is after the decimal point. i.e "010" is the value 1.0. 

Plasma parameters used for simulations:

Density (e,i) (m−3)      5.9e9
Te(K)                           1000
Ti(K)                            1000
me(kg)                        9.11e-31
mi(kg)                         4.55e-28

The hierarchical structure of the history.xy.h5 files:

The top-level group "current" is the current to the probe given for electrons and ions. Values are in Ampere. "energy" is the total kinetic and potential energies within the whole simulated domain for electrons (specie 0), ions (specie 1), and both species combined (total). The potential energy is not calculated per species for these simulations, and is therefore set to zero. Values are given in Joule.

The top-level group "potential" is the electric potential (bias) of the probe and is given in Volts.

Each datapoint is given each 1.5*10^(-9) s, giving it a sampling frequency of 6.67*10^(8) Hz.

In addition density data for the whole simulated domain is given in separate H5 files for (rho) electropns, ions, the combined charge density, and (phi) the electric potential. 

Example python ploting scripts is added for ease of access.
