Abstract

A tearing mode is a resistive magnetohydrodynamic (MHD) instability characterised by a helical perturbation current on a resonant surface in a tokamak plasma. In a classical tearing mode the per-turbation current is due to an unfavourable equilibrium current profile. The associated perturbation of the magnetic configuration leads to reconnection of the flux surfaces and hence to the formation of
