A noise-reducing algorithm for Particle-in-Cell plasma simulation

In this paper a new algorithm to reduce the noise effects in the Particle-in-Cell method for the Vlasov–Poisson system is proposed. The method is demonstrated on an example of a one-dimensional Riemann problem of plasma physics. Collisionless completely ionized non-isothermic plasma is considered. The model calculates only the ion movement (the electron density is described by the Boltz-mann distribution).
