A subspace of resonant magnetic perturbation (RMP) configurations for edge localized mode (ELM) suppression is predicted for H-mode burning plasmas at 15 MA current and 5.3 T magnetic field in ITER. Perturbations to the core plasma can be reduced by a factor of 2 for equivalent edge stability proxies, while the perturbed plasma boundary geometry remains mostly resilient. The striated domain of perturbed field lines connecting from the main plasma (normalized poloidal flux ) to the divertor targets is found to be significantly larger than the expected heat load width in the absence of RMPs. This facilitates heat load spreading with peak values at an acceptable level below on the outer target already at moderate gas fueling and low Ne seeding for additional radiative dissipation of the of power into the scrape-off layer (SOL). On the inner target, however, re-attachment is predicted away from the equilibrium strike point due to increased upstream heat flux, higher downstream temperature and less efficient impurity radiation.
This paper explores the use of resonant magnetic perturbations (RMPs) to suppress edge-localized modes (ELMs) in ITER's high-power fusion plasmas. It predicts a range of RMP configurations that can reduce core plasma disturbance while maintaining edge stability. The study also investigates the impact of these RMPs on the divertor, finding that they can spread the heat load and keep it at an acceptable level.
