ICI-4 E-N Collisional Current Simulations

<p>This dataset contains probe current data of PIC simulations decribed in the<br> paper &quot;Electron-Neutral collisions, effects on Langmuir Probes in the Lower<br> E-Region Ionosphere&quot;. The simulations are done for plasma parameters<br> representative of the lower E-region ionosphere, with probe biases in the<br> electron saturation regime.</p> <p>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. &quot;nocoll&quot; in a folder name means it&#39;s a simulation with no collisions.</p> <p>Plasma parameters used for simulations:</p> <p>Density (e,i) (m&minus;3)&nbsp; &nbsp; &nbsp; 9.597e10<br> Te(K)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;441<br> Ti(K)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 475<br> me(kg)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 9.109e-31<br> mi(kg)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;6.646e-27</p> <p>The hierarchical structure of the history.xy.h5 files:</p> <p>&nbsp;&nbsp; &nbsp;-current<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-electrons<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-dataset<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-ions<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-dataset<br> &nbsp;&nbsp; &nbsp;-energy<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-kinetic<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-specie 0<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-specie 1<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-total<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-potential<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-specie 0<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-specie 1<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-total<br> &nbsp;&nbsp; &nbsp;-potential<br> &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;-dataset</p> <p>The top-level group &quot;current&quot; is the current to the probe given for electrons<br> and ions.

The potential energy is not calculated per species for these<br> simulations, and is therefore set to zero. Values are given in Joule.</p> <p>The top-level group &quot;potential&quot; is the electric potential (bias) of the probe<br> and is given in Volts.</p> <p>Each datapoint is given each 5*10^(-10) s, giving it a sampling frequency of 2*10^(9) Hz.</p>
