摘要：

We present a three-dimensional model for numerical simulation of beam-plasma dynamics in an open magnetic trap. For specific parameters, it may be possible to observe a magnetic field push-out by the injecting particles and the formation of a configuration required for the plasma confinement (diamagnetic mode). For an axially symmetric case in cylindrical coordinates, it was shown that the diamagnetic configuration is possible; however, the complex non-linear nature of the processes in the diamagnetic trap and the decisive role of kinetic effects require the use of three-dimensional numerical simulation. Based on the results of the simulation, it will be possible to determine the required conditions for the formation and stability of the diamagnetic configuration.
