A model for the turbulence in the scrape off layer of tokamaks
The fluid theory of electrostatic perturbations in a scrape off layer plasma is analysed. The main difficulty is that the edge is predicted theoretically to be stable, while experimentally it is found to be unstable. A possible explanation lies in the fact that commonly used ballooning representation is not correct in the scrape off layer. An alternative representation is proposed which reproduces the instability of the edge in several simple configurations and explains many experimental features.
