Abstract
The method of co‐condensation of the elements from separate sources in vacuum to form intermetallic compounds has been used to make high current density superconducting ribbons. Evaporation rate monitors and control loops have been developed that allow control of the compound composition. The technique has been used to make continuous lengths of ribbon, and a number of compounds have been tested, Nb3Sn in particular. The condensation conditions are suitable for the fabrication of a microstructure consisting of alternate layers of compound superconductors and other materials, including normal metals and dielectrics. The microstructure assists in the pinning of transport currents in the presence of transverse magnetic fields, and in some apparent inherent stability against flux jumps.This publication has 0 references indexed in Scilit:
