Use of the stellarator expansion to investigate plasma equilibrium in stellarators
Abstract
A numerical code utilizing a large-aspect-ratio, small -helical-distortion expansion is developed and used to investigate the effect of plasma currents on stellarator equilibrium. Application is made to several existing and proposed stellarators. The modification of the equilibrium properties with pressure is strongly dependent on the vacuum-field configuration. The modular stellarator model which is investigated gives somewhat discouraging results because a large rotational transform, and hence large coil deformation, is needed to achieve high-beta equilibria.
