Abstract

In this work, we study the non–Gaussian dynamic of the magnetic field linesof a plasma confined in a toroidal configuration. We have used the Fourier pathstechnique in order to calculate the kurtosis of the magnetic field lines. We have alsocalculate numerically this quantity. The magnetic field lines are described by thestandard mapping. A comparison between our analytical and numerical calculations hasbeen done.
