Effects of the resonant magnetic perturbation on turbulent transport

Abstract

The effects of the resonant magnetic perturbations (RMPs) on the turbulent transport are analyzed in the framework of the test particle approach using a semi-analytical method. The normalized RMP amplitude $P_b$ extends on a large range, from the present experiments to ITER conditions. The results are in agreement with the experiments at small $P_b.$ The predictions for ITER strongly depend on the type of turbulent transport. A very strong increase of the turbulent transport is obtained in the nonlinear regime, while the effects of the RMPs are much weaker for the quasilinear transport.
