Summary

IT IS POSSIBLE TO DEFINE A CRITICAL ENERGY AS A MEASURE OF STABILITY. THE CRITICAL ENERGY IS THE MINIMUM ENERGY OF A DISTURBANCE TO CAUSE A QUENCH OF THE CONDUCTOR. IT IS A COMPLICATED FUNCTION OF CONDUCTOR GEOMETRY, OPERATING CONDITIONS AND DISTURBANCE PARAMETERS. THE THERMAL BEHAVIOUR OF THE CONDUCTOR IS DESCRIBED BY A SYSTEM OF SIX EQUATIONS. BY COMPARING THE MEASURED VALUES WITH THOSE CALCULATED, IT WAS SHOWN THAT THIS SYSTEM IS A COMPLETE AND QUANTITATIVELY CORRECT DESCRIPTION OF THE BEHAVIOUR OF A FORCE-COOLED SUPERCONDUCTOR. AN APPROXIMATE ANALYTICAL CALCULATION OF THE CRITICAL ENERGY WAS MADE TO SHOW THE DIFFERENT EFFECTS INVOLVED. A NUMBER OF EFFECTS, WHICH CAN LEAD TO DISTURBANCES ARE BRIEFLY MENTIONED.
