Modelling of Edge Plasma on JT-60U Tokamak by Using SOLPS5.0 Code

The edge transport code SOLPS5.0 is used to model edge plasmas in the experimental shots on JT-60U and the profiles of the transverse particle and heat transport coefficients D, χe and χi along the outer midplane are obtained by fitting the simulational results to the experimental data in L-mode shot 39090 and H-mode shots 37851, 37856. The modelling and fitting results show that within the pedestal region in H-mode shots 37851 and 37856 the radial particle transport coefficient D exhibits a significant drop, but, for L-mode shot 39090, the obvious drop in both D and χe was not found.
