This paper reports the results of detailed 3D modelling of the JT60-SA tokamak. Different computational tools have been used, ranging from a purely electromagnetic description to models including the plasma response. Detailed 3D finite elements meshes have been developed, including key conducting structures of JT60-SA. The positive comparison of results produced with different assumptions and independent codes increases confidence in results. Frequency-domain electromagnetic characterization of active coils has been achieved, as well as resistive wall modes growth rate computation

Abstract
This paper reports the results of detailed 3D modelling of the JT60-SA tokamak. Different computational tools have been used, ranging from a purely electromagnetic description to models including the plasma response. Detailed 3D finite elements meshes have been developed, including key conducting structures of JT60-SA. The positive comparison of results produced with different assumptions and independent codes increases confidence in results. Frequency-domain electromagnetic characterization of active coils has been achieved, as well as resistive wall modes growth rate computation
