On equilibrium magnetoplasma configurations in “Galatea-Belt” magnetic traps

Abstract

The computation results of equilibrium magnetoplasma configurations in magnetic Galatea-traps developed for solution of controlled thermonuclear fusion problem are presented in the paper. In traps of this type, electric current conductors creating a confining magnetic field are immersed into the plasma volume but do not come in contact with it. In numerical solution of two-dimensional boundary value problems with the elliptic Grad-Shafranov equation, distributions of the main parameters of the plasma and the magnetic field in the trap “Galatea-Belt” with two electric current conductors are obtained. In the series of numerical experiments, the research on how the problem parameters such as the maximum plasma pressure measured in magnetic units, the relative radius of the electric current conductors and the configuration transverse size influence on the properties and characteristics of the configurations is provided.
