Analytic, high-β solutions of the helical Grad-Shafranov equation

Research output: Contribution to journal › Article › peer-review

Abstract

A class of helical axis configurations having large helical aspect ratio was studied. To further simplify the calculations, it was assumed that the helix is in a tightly wound state. The solutions were found to develop a narrow boundary layer of strongly compressed flux. It was also suggested that the boundary layer can be associated with a strong localized current, which prevents the equilibrium from having zero net current.
