Tiivistelmä

When designing superconductor based magnets, it is of the utmost importance to be prepared for the loss of thermal stability under operation. In this paper, heat propagation during a quench in Roebel-cable based accelerator magnet prototype is predicted using one-dimensional approach. The heat diffusion equation is solved using the finite element method and thermal coupling between the turns is taken into account using thermal network model. However, when reducing the dimensions of the problem, modelling decisions are often unavoidable. Here, we present the challenges of this approach and discuss the appropriateness of these decisions via simulations.
