Abstract: The ITER tokamak is a very complex electromagnetic system that requires a careful assessment for for assuring its reliable operation as well as its mechanical integrity. In this paper we discuss the effects of the fast electromagnetic transients on the superconducting magnet system. Of particular complexity is the analysis of the quench detection system of the TF coils that can be improperly triggered by the spurious signals due to the inductive coupling with the plasma and the other active and passive magnetic field sources.

Keywords: Quench detection system, tokamak, eddy currents, integral formulation, electromagnetic transients
