Type of article: Article

Summary

A SUPERCONDUCTING MAGNET THAT IS NOT FULLY STABILIZED HAS INSTABILITY SUCH THAT A NORMAL ZONE, INDUCED BY A CERTAIN LOCAL DISTURBANCE, MAY LEAD TO TRANSITION OF THE MAGNET AS A WHOLE INTO A NORMAL STATE. APPROXIMATE EVALUATION OF PROPAGATION OF NORMAL ZONES IS OUTLINED AND SOME REMARKS ARE MADE ON ANISOTROPIC PROPAGATION IN MAGNETS. AN ANALYTICAL EXPRESSION PROPOSED BY WILSON IS PRESENTED AND COMPARED WITH EXPERIMENTAL RESULTS IN BARE AND INSULATED WIRES. BASIC IDEAS OF MAGNET PROTECTION FROM MECHANICAL AND THERMAL DAMAGE IN THE QUENCH PROCESS ARE EXPLAINED IN 2 TYPES OF PROTECTION SYSTEMS, BY AN EXTERNAL RESISTOR AND A < QUENCHBACK >.
