Computer simulation of diamagnetic regime in open magnetic trap

Preliminary results of numerical simulation of transition to regime of diamagnetic confinement in an axially-symmetric mirror trap are presented. Author’s two-dimensional modification of hybrid Particle-in-Cell model is used in the simulations. Formation of region with hot dense plasma and very small magnetic field is demonstrated. Evolution of plasma and magnetic field, as well as structure of the formed region are discussed and compared with simple analytical estimations.
