Description

In tokamak disruptions, a brief increase in the total plasma current-an Ip spike-frequently precedes the current quench. The Ip spike is commonly attributed to an internal reconnection event that lowers the internal inductance. Plasma current spikes seen in four fixed-boundary MHD disruption simulations support this explanation and are discussed in terms of the evolution of poloidal flux and poloidal magnetic energy.
