Summary

THE HEAT TRANSFER COEFFICIENT NEAR THE CRITICAL TEMPERATURE WAS DETERMINED FOR SEVERAL WHISKERS FROM THE INDIUM-LEAD ALLOY SYSTEM. FOR THIS PURPOSE THE HYSTERESIS OF THE VOLTAGE-TEMPERATURE TRANSITION CURVES AT FIXED CURRENTS I AND OF THE V-I CHARACTERISTICS AT FIXED HELIUM BATH TEMPERATURE WAS DETERMINED. THE ADVANTAGE OF USING MEASUREMENTS MADE WITH WHISKERS IS THAT THERE IS NO HEAT TRANSFER TO A SUBSTRATE AND NEGLIGIBLE HEAT TRANSFER TO THE CONTACTS. THE ONLY HEAT TRANSFER IS THAT TO THE SURROUNDING HELIUM.
