Equilibrium configurations of a toroidal plasma

Abstract

Equilibrium configurations of a toroidal plasma have been obtained, characterized by parameters for the gas pressure and the toroidal component of the magnetic field and by the aspect ratio of the torus. These configurations are symmetrical about the axis of the torus and fall naturally into two classes, corresponding to cases where the toroidal component of the magnetic field either is in the same direction over a cross-section of the torus or changes direction in the centre of the cross-section.
