Stability Study of High-β Flux-Conserving Equilibria

Abstract

The flux-conserving tokamak model suggested that rapid heating would yield equilibria with high relative energy density (P = 2p/B ) while nonetheless allowing control over q, the so-called safety factor for instability within the ideal magnetohydrodynamic plasma model. In this study, we show that this is adequate to provide stability to P values of 10%, if there is a superconducting metal shell in the vicinity of the plasma.
