Mathematical model of plasma transfer in a helical magnetic field

The paper presents the results of mathematical modeling of plasma transfer in a spiral magnetic field using new experimental data obtained at the SMOLA trap created at the Budker Institute of Nuclear Physics SB RAS. Plasma confinement in the trap is carried out by transmitting a pulse from a magnetic field with helical symmetry to a rotating plasma. New mathematical model is based on a stationary plasma transfer equation in an axially symmetric formulation. The distribution of the concentration of the substance obtained by numerical simulation confirmed the confinement effect obtained in the experiment. The dependences of the integral characteristics of the substance on the depth of corrugation of the magnetic field, diffusion and plasma potential are obtained.
