Abstract:

An AC bridge technique is described for measuring energy losses in multifilament MF superconductors due to alternating current flow in superconducting solenoids. Superconductivity and transient loss theory are briefly discussed, and the apparatus used to measure the losses is described in detail. Loss data as a function of frequency in the field region HH sub c1 was obtained from measurements on a number of solenoids which were wound from commercially available MF NbTi conductors. Some data is presented in which an external field of HH sub C1 is applied. Author
