Abstract : The objectives of the first year program are (1) to measure losses in practical superconductors, (2) to measure stability of superconductors in simulated field winding environments, and (3) to analyze the data obtained and make suggestions for improved superconductors. The loss behavior of superconductors was examined for alternating fields superimposed upon fixed bias fields simulating the field conditions that might be observed in a machine. An extensive set of measurements on one practical superconductor has been completed, and measurements on several other conductors have been initiated. A parallel effort has been sustained to extend the theory of losses under these field conditions. (Modified author abstract)
