The aim of this paper is to describe and model a sawtooth crash in RFX-mod2, compute the eddy currents induced in the stabilising shell surrounding the plasma for two alternative gap concepts and the subsequent error field. The sawtooth crash displacement of the plasma column is represented by a vacuum model coupled with a suitable magneto quasi static volume integral formulation.

Abstract
The aim of this paper is to describe and model a sawtooth crash in RFX-mod2, compute the eddy currents induced in the stabilising shell surrounding the plasma for two alternative gap concepts and the subsequent error field. The sawtooth crash displacement of the plasma column is represented by a vacuum model coupled with a suitable magneto quasi static volume integral formulation.
