Summary

The strand is an aluminum stabilized niobium-titanium/copper composite. Results of the analysis revealed that a radial distribution of temperature, as well as a longitudinal one, is formed distinctly due to a thermal disturbance, even within a small strand diameter of 1.8 mm. The profile of the radial distribution determines the necessary time for the conductor to recover from a normal state after the end of the disturbance. When a superconducting region reappears locally within the cross section, the conductor temperature decreases to the bath temperature with a 20 times higher rate than that before the reappearance.
