Self-consistent kinetic simulation of plasmas

An improved version of a kinetic simulation technique, the convected scheme (CS), is described. We present a ``long-lived moving cell'' version of the convected scheme and describe a recipe for implementation in detail. In collisional systems, the numerical diffusion in ``ballistic motion'' does not affect the simulation result of the regular CS, which can be set up to minimize numerical diffusion in collision processes. With the new scheme, the numerical diffusion is highly reduced even in nearly collisionless plasma systems, which is important in the modeling of low-pressure high-density plasma sources.
