• Plasma dynamics and structure are studied using a one-dimensional theoretical model for the anomalous transport diffusivities. In this analysis, the high collisional Pfirsch-Schlüter regime is examined and the anomalous particle diffusivity is employed. The reduction of the anomalous particle diffusivity and a steep gradient in the density profile can be obtained. This prediction may be the theoretical explanation for the internal diffusion barrier observed in super dense core plasmas of large helical device.
