Extract

An advanced two-chamber model for the main plasma scrape-off and the divertor chamber of a tokamak is constructed. It is studied in the framework of catastrophe theory. The model shows bifurcations in the topology of the equilibrium surfaces. The results are in qualitative agreement with some of the experimentally observed features of the H-mode transition.
