Abstract

Three dimensional free boundary magnetohydrodynamic equilibria that recover saturated ideal kink/peeling structures are obtained numerically. Simulations that model the JET tokamak at fixed 〈β〉 with a large edge bootstrap current that flattens the q-profile near the plasma boundary demonstrate that a radial parallel current density ribbon with a dominant m /n = 5/1 Fourier component at I_t = 2.2 MA develops into a broadband spectrum when the toroidal current I _t is increased to 2.5 MA.
