Abstract :
ANSYS has been used to compute eddy current loads in C-Mod antenna components due to a disruption. The antennas are on the outboard mid-plane, away from the direct involvement with halo currents, which characterize loading in the inner divertor and wall. Only inductively driven currents are computed. A rather complex but manageable electromagnetic model is used. Three of the antennas used in C-Mod were analyzed, Lower Hybrid, ICRH, and MHD antennas. The goal of these simulations was principally to quantify upper bound disruption loads.
