Abstract

A coupled thermal and electromagnetic model is formulated and solved to study the effects of radially non-uniform heat pulses and current densities in superconducting cable-in-conduit conductors. The results indicate that quench and stability behavior in cases with non-uniform radial conditions are more complicated and appreciably different than cases where uniform conditions are assumed over the cross-section of the cable. Specific cases are presented for an ITER-like CICC and energy margin calculations are compared with corresponding zero-dimensional estimates
