Turbulent Transport in Fusion Plasmas

This module gives an introduction into transport processes, where turbulent transport processes are emphasized. Different model-based and theoretical approaches are introduced and applied to concrete problems motivated by transport in magnetic confined fusion plasmas and their interaction with the wall. After a brief introduction in the common characterization of classical, neoclassical and turbulent transport and the associated transport coefficients based on the random walk picture of diffusion, non-diffusion-based theoretical descriptions of turbulent transport are studied in more detail. Non-diagonal transport processes are studied. Different types of random walk models as continuous time random walk or Levy flights in respect to sub- and superdiffusion are investigated. Finally non-local transport is highlighted.  

After successful completion of this module the student is able to

1. explain and characterize classical, neoclassical and turbulent transport in magnetically confined fusion plasmas
2. explain and characterize advanced models of transport as non-diagonal and non-local transport 
3. explain and characterize sub and superdiffusion
4. evaluate a concrete problem (not restricted to fusion problems) to apply the appropriate transport model
