TRANSIENT HEAT TRANSFER TO SUPERFLUID LIQUID HELIUM.

Type of article: Article

Summary

TRANSIENT HEAT TRANSFER FROM THIN SUPERCONDUCTING AND NORMAL WIRES TO SATURATED HELIUM II AND TO PRESSURIZED HELIUM II WAS INVESTIGATED. RECTANGULAR CURRENT PULSES OF 0.5 MILLISECOND DURATION AND LONGER WERE APPLIED TO THE SAMPLE WHILE VOLTAGE AND CURRENT WERE DETECTED. TO DETERMINE THE TEMPERATURE, THE TEMPERATURE CHARACTERISTIC OF THE WIRE RESISTIVITY WAS USED IN THE CASE OF NORMAL CONDUCTORS AND THE TEMPERATURE CHARACTERISTICS OF THE CRITICAL CURRENT IN THE CASE OF SUPERCONDUCTORS. DATA ARE REPORTED FOR BATH TEMPERATURES OF 2 K AND, IN THE CASE OF THE SUPERCONDUCTING SAMPLES, TRANSVERSE MAGNETIC FIELDS OF 1.5 T.
