THE INFLUENCES OF MAGNETIC SHEAR ON THE IMPROVEMENT OF THE QUALITY OF CONFINEMENT IN THE PLASMA OF TOKAMAK

Abstract

In this paper we have studied the influence of reversed shear on the improvement of the confinement’s quality in the plasma of tokamak and especially in reducing the anomalous transport. For that, we have used a special model for the drift wave fields. Comparison between particles trajectories for normal and reversed shear is carried out in 2D and 3D presentation. Also, the diffusion coefficient of particles for the two cases, normal and negative shear, is evaluated.
