Summary

TO DEMONSTRATE THE FEASIBILITY OF A PROPOSED DYNAMIC STABILIZATION METHOD (SEE BULL. 6/88, ABSTR. 88-2185), A MODEL COIL OF 8 T, 25 MEGAJOULES ENERGY WAS DESIGNED AT AN OVERALL CURRENT DENSITY OF 100 A/MM2. THE CONDUCTOR WAS 1 X 50 MM COPPER-NIOBIUM-TIN-COPPER STRIP AND WAS GRADED ACCORDING TO THE FIELD STRENGTH TO MEET THE DYNAMIC STABILITY REQUIREMENT. THE QUENCH ANALYSIS SHOWED A MAXIMUM TEMPERATURE RISE OF 420 K. THE PROTECTION BY AN EXTERNAL RESISTOR WAS ENOUGH TO SUPPRESS THE TEMPERATURE RISE DOWN TO 100 K. THESE RESULTS INDICATE THAT THE METHOD IS EFFECTIVE IN ATTAINING HIGH CURRENT DENSITY IN LARGE-SCALE MAGNETS AND ALSO SUITABLE FOR EMERGING HIGH FIELD MATERIALS.
