摘要：
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 with amplified diffusion coefficient is found under the conditions when trajectory trapping in the structure of the stochastic potential is effective.
