Summary

THE TRANSIENT HEAT TRANSFER BETWEEN SINGLE-CRYSTALLINE GERMANIUM CHIPS AND LIQUID HELIUM IS INVESTIGATED DURING THE APPLICATION OF LIGHT PULSES WITH DIFFERENT OPTICAL POWER TO THE GERMANIUM SAMPLE. THE STRONG TEMPERATURE DEPENDENCE OF THE ELECTRICAL CONDUCTIVITY OF GERMANIUM CONVENIENTLY SERVES FOR MONITORING THE TEMPORAL BEHAVIOUR OF THE SAMPLE TEMPERATURE DURING THE INPUT OF OPTICAL ENERGY. AFTER A CERTAIN TIME INTERVAL FOLLOWING THE BEGINNING OF THE LIGHT PULSE MUCH LONGER THAN THE THERMAL TIME CONSTANT, AN ABRUPT RISE OF THE SAMPLE TEMPERATURE IS OBSERVED, WHICH CAN BE UNDERSTOOD IN TERMS OF THE ONSET OF FILM BOILING.
