Three-dimensional fluid modeling of plasma edge transport and divertor fluxes during RMP control at ITER

Original language description

Predneseno:IAEA Fusion Energy Conference/24./. San Diego (US), 08.10.2012-13.10.2012] Results from three-dimensional modeling of plasma edge transport and plasma wall interaction during application of resonant magnetic perturbation for ELM control at ITER are presented. We show a systematic assessment of the impact of RMP application on the divertor fluxes and the plasma edge structure for the ITER standard H-mode scenario. A strong reduction of the thermal confinement is found with vacuum RMP fields applied. The divertor fluxes are redirected into a complex, three-dimensional pattern of helical magnetic fingers. These fingers stretch out as far as 60cm across the divertor targets yielding a spreading of the heat and particle fluxes with reduced peak heat loads. The sensitivity of the impact of the RMP fields on the level of plasma response, of the RMP amplitude and q95 is investigated.
