Temperature profiles in a poloidal cross section passing through the O-point of the magnetic island, as a function of the distance from the resonant surface. The solid line is the equilibrium profile (valid also for the first scenario), the dash-dotted line is the second scenario profile, and the dashed line refers to the third scenario.
Profile of in a poloidal cross section passing through the O-point of the magnetic island (solid line), as a function of the distance from the resonant surface, . The dashed line is the equilibrium profile. Note the discontinuity at the separatrix.
Comparison between the saturation relations for a typical bell shaped current density profile. The dot-dashed line is Thyagaraja’s dispersion relation with the normalizing length scale . The dotted line is Pletzer and Perkins relation. The small island [Eq. (26)] and the nonrelaxed large island [Eq. (36)], relations are represented by the cross and diamond solid lines, respectively.
Numerical results for the linear stability parameter in the new equilibrium (stars). The solid line interpolates the data and is represented by Eq. (D6).
The current density , dashed; and solid curve; with , in order to exaggerate the change. Note that the radius is normalized to the tokamak minor radius.
