| description | •Fast and efficient algorithms for the solution of 3D eddy current problems.•Eddy current problems in complex magnetic confinement fusion devices.•Numerical studies aiming at the upgrade of the MHD control system of RFX-mod.
RFX-mod is a device equipped with a state-of-the-art system for active control of MHD instabilities, which consists of 192 saddle coils and 192 radial field sensors. In order to further extend its operational space an upgrade of its magnetic front-end is now being studied. In this paper we focus on the implementation of fast and efficient algorithms for the 3D electromagnetic analysis of the effect of the designed magnetic front-end on the MHD control system in RFX-mod2, in the presence of complex conducting structures surrounding the plasma. |
