摘要：
The Langevin equation method is developed for the simulation of elastic collisions in non-Maxwellian plasmas by particle methods. The properties of random processes are shown to allow splitting not only of collisions between different compounds but even splitting inside a compound. The latter drastically simplifies extension of the method for colliding plasmas. The method is also verified by obtaining characteristics of runaway electron generation under an external electric field and under an external magnetic field. Published by AIP Publishing.
