The apparatus described here is designed to measure the total ac loss in 2G tape subjected to a rotating magnetic field of up to 1 Tesla applied perpendicular to the tape axis and at speeds of up to 3600 rpm, while carrying a transport current. Both thermal and electrical measurement techniques are incorporated in the apparatus. The data collected from the apparatus will be used to assist the design of superconducting machines in which the superconductor is used for the stator as well as the rotor and where the minimization of AC losses is crucial to the success of the machine. The measurement of ac losses will give results that are difficult to predict from mathematical modeling.
