학회: International Conference on Parallel Computational Technologies

A new 2D numerical model of the diamagnetic regime of an open plasma confinement trap is presented. A hybrid numerical model based on the kinetic approximation for the ion components of the plasma and the injected beam and the hydrodynamic approximation for electrons (PIC-MHD) is considered. The particle-in-cell method is used to solve the Vlasov kinetic equation. A new algorithm for solving the equations of motion of charged particles in the electromagnetic fields is used. This algorithm takes into account the condition of immutability of the electromagnetic fields at each time step. The parallel computing algorithm is based on decomposition with respect to space and particles. The basic principles of diamagnetic plasma confinement were verified, and various options for beam injection were considered. The calculation parameters were chosen close to the parameters of the experiments at the CAT facility (BINP SB RAS).
