EDGE2D-EIRENE modelling of the inter-ELM phase of H-mode plasmas on JET

Abstract The edge transport code EDGE2D-EIRENE has been used to model the inter-ELM phase of H-mode plasmas on JET. A reference plasma was simulated and matched to outer mid-plane profiles and to the heat load distribution at the outer target. While the simulated parallel saturation current was within experimental constraints from Langmuir probes, the target electron temperature was slightly overestimated (factor ∼1.2) compared to the upper experimental range. A deuterium scan was carried out from the simulation of this (lowest fuelled) reference plasma and compared to the same experimental scan. In all simulations, carbon radiation was found to be the dominant power loss channel at the outer target.
