Description

Diffusion of stochastic magnetic field lines is studied in a toroidal geometry. General expressions for the radial diffusion coefficient are obtained in various physically important situations. The Poincare representation of magnetic field lines is reduced to discrete mappings and the corresponding diffusion coefficients are derived. The diffusion processes taking place near the threshold to global stochasticity are also discussed
