The Vlasov-Maxwell Equations for Self-Consistent Electromagnetic Fields:

Applications to Mathematical Simulation of Multicomponent Plasmas in a Target Trap

Prof. Galina Lazareva, Institute of Computational Mathematics and Mathematical Geophysics SB RAS, Russia

A plasma target for high neutralization of powerful beams of negative ions is considered. The plasma is held in a magnetic trap with multipole magnetic walls. The inverse of the magnetic tube was proposed to limit the expiration of the plasma through the inlet and outlet ports in the target. Mathematical modeling of plasma dynamics in the trap was performed by the PIC method. The basic idea of the PIC method and new analytical tests for numerical models and codes are presented. Plasma distribution in the trap the efficiency estimate of particle confinement in the magnetic field were obtained. Simulation results were compared with experimental data.
