Abstract

The development of methods for the active control of magnetohydrodynamic (MHD) instabilities and the correction of error fields is mandatory in view of robust magnetic confinement in future fusion reactors. Two numerical codes (CAFE, CARIDDI) have been used to simulate the dynamic response of MHD control systems in large fusion devices. Their main pros and cons are discussed. As reference test case, the frequency domain characterization of a key system for MHD control in the large JT-60SA fusion device, namely the resistive wall mode active coil set, is considered.
