Contribution to the study of the non-Gaussian dynamics of stochastic magnetic field lines in a toroidal geometry (tokamak)

摘要

In this work, we study the non-Gaussian dynamic of the magnetic field lines of a plasma confined in a toroidal configuration. We have used the Fourier paths technique in order to calculate the kurtosis of the magnetic field lines. We have also calculate numerically this quantity. The magnetic field lines are described by the standard mapping. A comparison between our analytical and numerical calculations has been done.
