Summary

THE MAGNETIC STABILITY OF A DYNAMICALLY STABILIZED NIOBIUM-TIT ANIUM OR NIOBIUM-TIN STRIP CONDUCTOR HAS BEEN ANALYSED THEORETICALLY WHEN THE EXTERNAL FIELD IS APPLIED PERPENDICULAR TO THE WIDE PLANE OF THE CONDUCTOR. UNDER THE CONDITION THAT THE CONDUCTOR IS FACE-COOLED, AN EXPRESSION OF THE LIMITING CURRENT DENSITY OF STABILITY I HAS BEEN DERIVED. IT SHOULD BE NOTED THAT I IS INDEPENDENT OF THE WIDTH OF THE STRIP CONDUCTOR. AN AVERAGE CRITICAL CURRENT DENSITY AS HIGH AS 300 A/MM2 CAN BE ATTAINED WITHOUT MAGNETIC INSTABILITY. AS A TYPICAL EXAMPLE, COPPER/NIOBIUM-TIN/COPPER CONDUCTOR IS INVESTIGATED. FROM THE RESULTS IT IS SHOWN THAT THE STRIP CONDUCTOR IS STABLE ENOUGH TO BE WOUND INTO SUPERCONDUCTING MAGNETS.
