The application of the statistical method and finite-difference method for low-temperature plasma diagnostics problem solution by the flat probe with Coulomb collisions

In the article the mathematical model, describing strongly ionized collisional plasma dynamics near the flat probe, is formulated. The mathematical model includes the Fokker–Planck equation and the Poisson equation. Two methods of getting solution are presented. One of these methods is the Monte-Carlo Method, other is combination of the splitting method and the Particle-In-Cell Method.
