Abstract
A thermometric apparatus to measure AC losses in superconductor wires for 50 Hz applications is described. This method consists in isolating the sample from a helium bath via a thermal resistance. Dissipated po wer is determined by two thermometers located on both edges of a therm al resistance. The measurement's calibration is done using an ohmic he ater. The measurement accuracy is 10% for losses in excess of 2 mW/m.
