Three-dimensional analysis of JT-60SA conducting structures in view of RWM control

tThis paper reports the results of detailed 3D modelling of the JT60-SA tokamak. Different computationaltools have been used, ranging from a purely electromagnetic description to models including the plasmaresponse. Detailed 3D finite elements meshes have been developed, including key conducting structuresof JT60-SA. The positive comparison of results produced with different assumptions and independentcodes increases confidence in results. Frequency-domain electromagnetic characterization of active coilshas been achieved, as well as resistive wall modes growth rate computation.
