Edge plasma modelling for transport analysis on JT-60U tokamak

At the edge plasma the cross-field transport is thought to play a major role in determining the shape of density and temperature profiles. The edge plasma transport code B2.5I is used for modelling experimental measurements of the edge plasmas in L-mode and H-mode shots on JT-60U tokamak and the radial transport coefficients at the edge have been obtained by matching the results of the transport code directly to experimental measurements, by which the radial transport coefficients are determined by the combination of the experiment and the transport modelling.
