Abstract

The stochastic edge magnetic field topology with applied resonant magnetic perturbations can explain the increased L-H power threshold [1,2] with applied n=3 resonant magnetic perturbations (RMP) in low rotation, ITER-similar-shape (ISS) plasmas in DIII-D. At low, ITER-relevant edge collisionality, the L-H power threshold is increased by a factor of almost three with respect to the Martin scaling. In this paper, reduced L-mode E×B shear with applied RMP is established as the likely cause of the increased L-H transition power threshold.
