Type of article: Article

Summary

A METHOD FOR MAKING LARGE SCALE ELECTRICAL CONTACTS TO YTTRIUM BASED HIGH TEMPERATURE SUPERCONDUCTORS IS DESCRIBED. THIS INVOLVES FLAME SPRAYING OF COPPER WIRE ONTO AN ABRASION CLEANED SUPERCONDUCTOR SURFACE. USING THIS TECHNIQUE CONTACT RESISTIVITIES OF THE ORDER OF 500 MICRO-OHMS/CM2 CAN BE EASILY ACHIEVED. THIS IS A PROCESS WHICH CAN BE A STEP TOWARDS THE PRODUCTION OF CRYOSTABILIZED HIGH CRITICAL TEMPERATURE SUPERCONDUCTORS OUTSIDE THE LABORATORY ENVIRONMENT.
