Abstract

An ideal magnetohydrodynamic equilibrium and stability code is used to study ballooning modes in torsatrons. The most dangerous modes turn out to be those with low poloidal and toroidal wave numbers. Beta limits for equilibrium and stability are determined for an [unk] = 2 ultimate torsatron with large [unk] = 1 and [unk] = 3 sidebands.
