Needle Langmuir Probe - guard and boom effects

The dataset includes two distinct simulation setups named "LG_experiment" and "RG_RP_experiment". A detailed explanation of the datasets is given in the article "Effects of Guard and Boom on Needle Langmuir Probes Studied With Particle in Cell Simulations"

The naming convention of the included folders is a description of the simulation contained within with the convention following the order: probe length (Lp) probe radius (Rp) length of guard (Lg) guard radius (Rg) probe voltage (Vp)  boom voltage (Vb). Each descriptor has a numeric value with three numbers where the last is the first decimal, eg 010 corresponds to 1.0. All lengths are given in Debye Lengths.

The LG_experiment is a simulation setup where all parameters are fixed except the guard length, to investigate the effects of the guard length on the cylindrical Langmuir probe.

The RG_RP_experiment is a simulation setup where all parameters are fixed except the guard radius, to investigate the effects of the guard radius on the cylindrical Langmuir probe. Two guard radii are included.

Each simulation folder contains  three data files. The pictetra.hst file which is the history of the probe-guard-boom system. The index values 0,1,2 correspond to the probe,guard and boom respectively. (see the included plot.py). The scc*.vtk files contain surface values on the probe-guard-boom system, and the pictetra*.vtk files contain plasma values through the simulated domain.

A minimal python example for plotting the currents is included in the file "plot.py".
