Edge localised modes (ELMs) are magneto-hydrodynamic (MHD) instabilities that drive filamentary plasma eruptions in high confinement tokamak discharges . Gaining an improved understanding of ELMs is important ; in future fusion reactors such as ITER, ELM heat fluxes will need to be limited to ensure durability of divertor materials . A new divertor configuration, the Super-X, will be tested on the MAST-U tokamak. The Super-X has a closed divertor designed to retain neutrals and could offer a solution for divertor heat flux control due to the increased connection length and magnetic flux expansion . The effect of the new magnetic configuration on ELMs is unknown.
