Abstract

Turbulent ion motion caused by sawtooth crash is analyzed in the framework of the magnetic stochasticity model of the sawtooth crash. The average current profile changes much more slowly than the pressure profile after the onset of the crash, so that inhomogeneity of the parallel current along the field line is generated. This causes a perpendicular current with a short scale length, leading to the ion cross field motion.
