Quench in superconducting magnets. I. Model and numerical implementation

Abstract

A new simple, self-consistent theoretical model is presented that describes the phenomena of quench propagation in Cable-in-Conduit superconducting magnets. The model circumvents many of the difficulties associated with obtaining numerical solutions in more general existing models. Specifically, a factor of 30–50 is gained in CPU time over the general, explicit time-dependent codes used to study typical quench events. The corresponding numerical implementation of the new model is described and the numerical results are shown to agree very well with those of the more general models, as well as with experimental data.
