Type of article: Article

Summary

THE TECHNIQUE IS SIMILAR TO A THERMAL CONDUCTIVITY MEASUREMENT. THE SAMPLE IS PLACED IN A VACUUM VESSEL AND COUPLED TO THE HELIUM BATH BY A THERMAL RESISTANCE. THE STATIONARY TEMPERATURE INCREASE OF THE SAMPLE IN AN AC FIELD IS A MEASURE OF THE LOSSES. CALIBRATION IS DONE WITH THE PULSE FIELD OFF USING AN OHMIC HEATER CONNECTED TO THE SAMPLE. THERE IS NO NEED FOR CALIBRATED TEMPERATURE SENSORS.
