Turbulent transport in fusion plasmas

Abstract

In order to improve the confinement time for tokamak type fusion reactors the nature of turbulent transport in fusion plasmas needs to be better understood. In this thesis the transport predicted by an advanced uid model, called the Weiland model, will be investigated analytically to further the understanding of which factors contribute to both inward and outward transport in various circumstances. The analytical expressions are then used to investigate how the flux of particles and heat relate to the density and temperature gradients in the plasma.
