The cryogenic engineering of ceramic superconductors at temperatures below 77 K.

Author(s) : RICHARDSON R. N., TAVNER A. C. R.

Summary

The current densities-magnetic fields characteristics of present high temperature superconductors show a significant improvement with decreasing temperature. While the most attractive refrigerant would be liquid nitrogen at 77 K under 1 bar, the paper examines the possible and practical use of temperatures below 77 K for power engineering applications. The types of refrigeration to be employed, whether using wet cooling, gas cooling or dry cooling via thermal contact are also examined.
