QUENCH IN SUPERCONDUCTING MAGNETS .1. MODEL AND NUMERICAL IMPLEMENTATION

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