A theoretical analysis of operating temperature dependent normal zone propagation (NZP) has been performed in an adiabatic superconducting magnet over the temperature range 4.2-80 K. Because of the inverse dependence of NZP velocity on winding heat capacity, which increases sharply with temperature,

โฆ Synopsis
A normal zone propagation model has been developed for superconducting composites under adiabatic conditions. It is based on the Whetstone-Roos model, originally developed for normal zone propagation in adiabatic wires of unclad superconductor. The model takes into account the temperature and magnetic field dependent material properties, for both superconductor and matrix metal. Analytical results agree well with experimental data.
