Description

The analysis of the flight particles trajectories in the tokamak magnetic configuration under the effect of weak electrostatic perturbations is presented. The trajectories with the parameters, enabling determination of the diffusion spatial scale, are obtained in the course of numerical calculations in the drift approximation. The particles and waves resonance interaction is considered. The possibility of the collisionless diffusion appearance in the strong turbulence mode is analyzed

Abstract (Russian)

Представлен анализ траекторий частиц в магнитной конфигурации токамака под действием слабых электростатических возмущений. В результате численных расчетов в дрейфовом приближении получены траектории, параметры которых позволяют определить пространственный масштаб диффузии. Рассматривается резонансное взаимодействие частиц и волн. Проанализирована возможность возникновения бесстолкновительной диффузии в режиме сильной турбулентности
