Null collision Monte Carlo simulation model for particle-in-cell method

The article discusses the original null collision approach for modeling collisions in plasma for particle-in-cell method. A distinctive feature of the method is the simulation of particle collisions without the use of trigonometric functions and calculation of pairwise collisions (as is done in classical papers), which significantly increases the speed of the developed algorithms. The developed algorithms are used in other software systems for modeling particle motion in a magnetic field. Comparison of the results of system's operation in the presence of collisions and in their absence is made.
