A mechanism for the sawtooth collapse
A mechanism is proposed to explain how the sawtooth precursor, a transient macroscopic tearing mode, can trigger the sawtooth collapse. The physical model and scaling considerations are described. The terms of equations describing the background and fluctuations involved are then ordered and their consequences are obtained and discussed. The continuity and first order parallel momentum equations, which describe the evolution of the background owing to the anomalous fluxes, are solved analytically, enphasising the physical interpretation of the solution. The paper concludes with a comparison with other collapse models.
