Title: Ac losses of Nb/sub 3/Sn. [Rods and tapes]

Conference · · IEEE Trans. Magn.; (United States)
OSTI ID:7358764

60-Hz losses were measured at 4.2/sup 0/K in a number of Nb/sub 3/Sn rods and tapes produced by the bronze-diffusion process and in commercial Nb/sub 3/Sn tapes. At low fields (less than or equal to 900 Oe), losses vary by more than two orders of magnitude among the different samples and are related to surface topography. At high fields (greater than or equal to 2 kOe) the variation among samples is much less, and depends mainly on the bulk critical current density J/sub c/. The losses are analyzed quantitatively in terms of the critical state model, including a surface current. (auth)
