Abstract. Particle diffusion in a given electrostatic turbulence with a
finite correlation length along the confining magnetic field is studied in
the test particle approach. An anomalous diffusion regime of amplified
diffusion coefficients is found in the conditions when particle trapping in
the structure of the stochastic potential is effective. The auto-generated
radial electric field is calculated.
