Origin of Tokamak Density Limit Scalings

The onset criterion for radiation driven islands [Rebut and Hugon, ] in combination with a simple cylindrical model of tokamak current channel behavior is consistent with the empirical scaling of the tokamak density limit [Greenwald, Nucl. Fusion 28 (1988) 2199]. Many other unexplained phenomena at the density limit are consistent with this novel physics mechanism.
