EDGE2D-EIRENE simulations show that for a H-mode JET discharge (92168) the dominant atomic neutral deuterium source at the separatrix originates from the inner divertor target. Within JETTO-EIRENE neutral sources are placed at the X-point and outer midplane (OMP). For fixed electron and ion temperature, transport and neutral temperature it is observed that the 1/ne,ped scaling (from reference the Neutral Penetration model (NPM) ) is observed when fueling at the OMP but not at the X-point. This is due to measuring the resultant density profiles at the OMP. When measuring the X-point fueling cases along the same coordinate which neutrals are injected along the 1/ne,ped scaling is observed. Experimentally this scaling could be checked by remapping experimentally measure pedestal density profiles to a coordinate in the Z direction which intersects the X-point. Furthermore EUROPED  could accept a density profile defined on this coordinate system which would negate the need for a E factor, assuming that neutral source enters exclusively at the X-point.
