Project

Effect of edge plasma turbulence in tokamaks on the particle transport (IAA100430502)

The project continues in our works dealing with an anomalous diffusion of particles in a simple model of the edge plasma turbulence. Our approach was based generation. We shall study the diffusion in more realistic potentia...

Anomalous diffusion of plasma particles in electrostatic turbulence and systems of magnetic islands. (IAA1043201)

It is generally accepted that the low frequency turbulence in tokamaks causes of a diffusion of particles. Recently, we have proposed a new simple model of diffusion, based on ExB diffusion of particles in a spatia...
