ICI-4 E-N Collisional Current Simulations

This dataset contains probe current data of PIC simulations decribed in the<br> paper "Electron-Neutral collisions, effects on Langmuir Probes in the Lower<br> E-Region Ionosphere". The simulations are done for plasma parameters<br> representative of the lower E-region ionosphere, with probe biases in the<br> electron saturation regime. Each simulation has its own folder denoting the power of the electron-neutral<br> collision frequency, and probe bias. For example the subfolder 2-4.5V has a<br> history.xy.h5 file (in HDF5 format) containing data for a simulation using a<br> electron-neutral collision frequency proportional to 10^2, and a probe bias of<br> 4.5V. "nocoll" in a folder name means it's a simulation with no collisions. Plasma parameters used for simulations: Density (e,i) (m−3) 9.597e10<br> Te(K) 441<br> Ti(K) 475<br> me(kg) 9.109e-31<br> mi(kg) 6.646e-27 The hierarchical structure of the history.xy.h5 files: -current<br> -electrons<br> -dataset<br> -ions<br> -dataset<br> -energy<br> -kinetic<br> -specie 0<br> -specie 1<br> -total<br> -potential<br> -specie 0<br> -specie 1<br> -total<br> -potential<br> -dataset The top-level group "current" is the current to the probe given for electrons<br> and ions. Values are in Ampere. "energy" is the total kinetic and potential energies within the whole simulated<br> domain for electrons (specie 0), ions (specie 1), and both species combined<br> (total). The potential energy is not calculated per species for these<br> 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<br> and is given in Volts. Each datapoint is given each 5*10^(-10) s, giving it a sampling frequency of 2*10^(9) Hz.
