Electrical AC loss measurements of Bi-2223 tapes, performed under the Brite EuRam research programme SACPA

A series of electrical AC loss measurements on Bi-2223 tapes have been perf ormed under the Brite Euram project SACPA. This included, for the first tim e, a round-robin of independent self-field AC loss measurements between fou r laboratories. The very close agreement of data demonstrates the validity of the electrical technique and lays the basis for a measurement standard. Other preliminary measurements in SACPA showing the variation of losses wit h frequency, temperature and applied DC field are also reported. (C) 1998 E lsevier Science B.V. All rights reserved.
