%X Density modulation experiments are successfully conducted on HT-7 ohmic discharge to investigate particle transport coefficients: diffusion coefficients D and convection velocity V. The particle transport is studied at low (1.5×1019m-3) and high (3×1019 m-3) density regimes. The clear differences are observed that D is 0.42m2/s and 0.17m2/s, V is 4.7m/s (outward) and 1.6 m/s (inward) for low and high density plasmas respectively, where spatially constant D and V(r) = (r/a)V0 were assumed for the analysis.
