| Abstract: | The edge plasma transport code SOLPS5.0 is used for modelling edge plasmas in the experimental
shots on JT-60U tokamak and the pro les of the radial particle and heat transport coecients D, e and i along
the outer midplane have been obtained by tting the code results to the experimental measurement in L-mode shot
39090 and H-mode shots 37851, 37856. The experimental measurement used for tting includes the pro les of electron
temperature and density along the outer midplane, the pumping speed, the total particle
ux from the core boundary
to the computational region and the
ux density of neutrals near the outer wall. The modelling and tting results
show within the pedestal region in H-mode shots 37851 and 37856 the radial particle transport coecient D has larger
drop, but, for L-mode shot 39090, the obvious drop of D and e has not been found. |
