Three-dimensional magnetohydrodynamic equilibrium of quiescent H-modes in tokamak systems
Three dimensional free boundary magnetohydrodynamic equilibria that recover saturated ideal kink/peeling structures are obtained numerically. Simulations that model the JET tokamak at fixed <beta > = 1.7% 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.
