Abstract

The flux-conserving tokamak model suggested that rapid heating would yield equilibria with high relative energy density ($\ensuremath{\beta}=\frac{2p}{{B}^{2}}$) 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 $\ensuremath{\beta}$ values of 10%, if there is a superconducting metal shell in the vicinity of the plasma.
