FEM Modeling of Quench Phenomena in NbTi Coils

The design process of superconductor coils must include the optimization of the quench protection system. A reliable model for quench analysis of superconductor coils would consequently be highly beneficial. A numerical tool able to cope with the simulation of the quench phenomena, involving electromagnetic, thermal and circuital dynamics coupled each to the others, has been recently proposed. In this paper the mathematical model is briefly revised and extended to take into account the presence of metallic support structures, needed for the coil assembly and cryogenic purposes
