Abstract

A dimensionally correct expression for the scaling of the giant ELM frequency based on the MHD interchange instability is presented. Tokamak experiments reveal that ELM events can happen well below the ideal MHD threshold. The physical model is extended in two ways, namely to include geometrical effects and dissipative terms. It is shown that both effects can play an important role in the explanation of the ELM physics.
