Summary

MEASUREMENTS OF SUPERCURRENT TRANSPORT AND CURRENT DENSITY IN EXPLOSIVELY FABRICATED SUPERCONDUCTING PROTOTYPES HAVE BEEN ERRATIC, WITH CURRENT DENSITIES MEASURED TO BE IN EXCESS OF 1,000 A/CM2. THIS ERRATIC BEHAVIOUR APPEARS TO BE RELATED TO THE DEGREE OF CONSOLIDATION ACHIEVED FOR YBACUO POWDERS AND, MORE SPECIFICALLY, TO THE CONNECTIVITY OR INTERFACIAL STRUCTURE AT INDIVIDUAL, CONTACTING, SUPERCONDUCTING PARTICLES. OBSERVATIONS OF GRAIN BOUNDARIES AND INTERFACE PHASE REGIONS CAST SOME LIGHT ON THE PROSPECTS FOR PRODUCING GOOD CONNECTIVITY THROUGH OPTIMIZING THE CONSOLIDATION PROCESS AND PROCESS PARAMETERS AS WELL AS THE ELIMINATION OF SURFACE REACTIONS ON PARTICLES PRIOR TO CONSOLIDATION, OR THERMAL EFFECTS DURING CONSOLIDATION.
