Disruptions and turbulence in tokamaks
Abstract
The proposition is made that disruptions in tokamaks are due to the onset of a fine-grain turbulence: correlated kinetic and magnetic eddies liberate part of the poloidal magnetic energy and feed a hierarchy of smallest eddies ultimately dissipated by resistivity or viscosity. The turbulence propagates radially at velocities which agree with observations and produces the voltage spikes observed in q equals 2 disruptions.
