Summary

CONSIDERING THE STABILITY OF A SUPERCONDUCTING MAGNET WHICH IS IRRADIATED BY HIGH ENERGY PULSE RADIATION IN A FUSION REACTOR, THE DISRUPTION AND RECOVERY OF THE SUPERCONDUCTING STATE IN A SHORT TIME (A FEW MICROSEC) AFTER PULSE IRRADIATION WERE INVESTIGATED WITH A SHORT LIGHT PULSE (8 AND 30 NANOSEC) INSTEAD OF HIGH ENERGY RADIATION. WHEN CURRENT FLOWED IN THE SUPERCONDUCTING LEAD, THE VOLTAGE PULSE WAS INDUCED BY IRRADIATION AND MEASURED WITH A FAST DETECTION SYSTEM HAVING A TIME RESOLUTION OF ABOUT 10 NANOSEC. THE OBSERVED DECAY TIME OF THE RESISTANCE AGREES WITH THAT WHICH WAS EVALUATED FROM A HEAT TRANSFER EQUATION. THIS INDICATES THAT THE MECHANISM OF DISRUPTING AND RECOVERING THE SUPERCONDUCTING STATE CAUSED BY THIS PULSE IRRADIATION WAS EXPLAINED ONLY BY THE THERMAL EFFECT.
