Abstract

The systematics of magnetic fluctuations resulting from the nonlinear evolution of high-β_p long parallel wavelength resistive magnetohydrodynamic modes are studied for circular tokamak plasmas with a free boundary. Large-amplitude fluctuations cause increased magnetic field stochasticity with increasing εβ_p. These fluctuations, when coupled to an anomalous energy loss mechanism, may lead to β_p saturation with respect to total input power.
