Type of article: Article

Summary

CRACK-INDUCED TEMPERATURE SPIKES IN EPOXY-COATED TEST WIRES UNDER TENSILE LOAD WERE MEASURED TO STUDY THE ENERGY SPECTRUM OF STRESS-INDUCED CRACKS IN THE WINDINGS OF EPOXY-IMPREGNATED HIGH-CURRENT DENSITY SUPERCONDUCTING MAGNETS. NO TEMPERATURE-SPIKE CAUSING CRACKS WERE OBSERVED FOR WIRE STRESSES LESS THAN 180 MEGAPASCALS, A LEVEL NORMALLY NOT EXCEEDED IN THE WINDINGS OF EPOXY-CRACK-PLAGUED SUPERCONDUCTING MAGNETS. POSSIBLE EXPLANATIONS ARE PRESENTED.
