Abstract

The tape strip or strand of superconductor material is wound around a central core and the whole surrounded by a tubular protective outer through which the cryogenic coolant flows. The tape is made by the melt spin method i.e. it flows in molten phase over the surface of a rotating quenching machine so that the rate of solidification of the molten superconductive alloy used is 15-330 m/s. The alloy is based on Nb, Ta, Ti, Zr, V, Mo and/or U and the alloy metals are chosen from Sn, Al, Si, Ga or from one of the above basic components. Superconductive properties are exhibited at temps. >20 degrees K and liquid H2 can be used as coolant instead of liquid He.
