Symmetry-breaking induced transport in the vicinity of a magnetic island.

Abstract

It is shown that in the vicinity of a magnetic island, the symmetry of the equilibrium magnetic-field strength B is broken due to the finite width of the islands. The magnitude of this broken symmetry is of the order of (deltaB/B)(1/2), where deltaB is the perturbed magnetic-field strength. This leads to enhanced plasma transport. The symmetry-breaking induced-transport flux in tokamaks with islands is calculated.
