Abstract

Theory of the anomalous transport is developed, and the unified formula for the L- and H-mode plasmas is presented. The self-sustained ballooning-mode turbulence is solved in the presence of the inhomogeneous radial electric field, E{sub r}. Reductions in transport coefficients and the amplitude and decorrelation length of fluctuations due to E{sub r}` are quantitatively analyzed. Combined with the E{sub r}-bifurcation model, the thickness of the transport barrier is simultaneously determined. (author).
