Abstract

We present a two dimensional numerical model for predicting the normal zone propagation velocity in Aluminum stabilized Rutherford NbTi cables. By solving two coupled differential equations under adiabatic conditions, the model takes into account the thermal diffusion and the current redistribution process following a quench. Both the temperature and magnetic field dependencies of the materials properties are included. We study the influence of the thickness of the cladding on the propagation velocity for varying operating current and magnetic field. To assist in the comprehension of the numerical results, we introduce an analytical formula for the longitudinal normal zone propagation.
