Tokamak-like equilibria at beta close to unity

Results are reported for a computer study of tokamak equilibria in which a modest vertical elongation and the effect of a flat q-profile were combined to achieve as high a beta as possible.

Description
Summary:Results are reported for a computer study of tokamak equilibria in which a modest vertical elongation and the effect of a flat q-profile were combined to achieve as high a beta as possible. The computer calculations were performed mainly for the geometry of a High-Beta Tokamak experiment (a racetrack-shaped cross section and an aspect ratio of 2.5); other geometries considered include a circular cross section and a 'D' shape. Local beta equilibria of 80% to 90% were obtained for the racetrack cross section, demonstrating that there is no beta limit for the equilibrium in such a tokamak.
