| Abstract: | The Ion Cyclotron Resonance Heating (ICRH) antennas are essential to couple additional power to the plasma during the experiment. The radio frequency waves are injected into the plasma by the current straps, which face the plasma directly. Therefore, like the other plasma facing components, they experience potentially high electromagnetic (EM) loads (i.e. the Lorentz force density J x B) given by the interaction of the total magnetic field B and the induced current density J, caused by rapid plasma current and position variations in case of a disruption event. Considering the Divertor Tokamak Test (DTT) facility as reference for the ICRH antenna geometry and the plasma scenarios data, the present work firstly investigates the eddy currents pattern and the forces density distribution on the ICRH antenna components by means of the eddy current code CARIDDI. A major disruption event with a current quench time of 4 ms has been simulated starting from reference single null equilibrium both at the start of flat-top and at the end of flat-top. The resulting EM loads have been imported on the current straps mechanical model to perform a preliminary structural analysis. • Complete electromechanical analysis for the DTT ICRH antenna current straps. • 3D induced currents and forces due to a Major Disruption are computed and compared. • EM loads mapping onto a detailed mechanical mesh through the IDOM LDEV method. • Static structural analyses are performed in Ansys for the worse loading conditions.
