Radiative Thermal Instability and Bifurcation

A radial hydrodynamic model is used to investigate the radiative thermal instability in the scrape-off layer by applying a linear stability analysis of existing equilibrium states. Phase space trajectories are analyzed to derive conditions of their existence and bifurcation. Equilibrium profiles are calculated for the cases of homogeneous plasma temperature, plasma density and self-consistency. Unstable perturbations, localized in the scrape-off layer, may lead to a strongly radiating detached plasma belt.     

The Influence of Neutral Particle Sources on the Dynamics of Tokamak Plasmas. II. Particle Dynamics and Induced Electromagnetic Fields

In part I of our paper [1] a kinetic theory of the influence of neutral particle sources on the dynamics of tokamak plasmas has been developed and the general solution of this problem has been given for an arbitrary source function. By the use of these results we calculate in this part II the particle's distribution function for different simple source functions. In the case of recycling perpendicular to the limiter surface we derive analytical expressions for the charge density, the induced electric potential and the anomaleous electron density flux transverse to the magnetic field.
