摘要
Characterizing critical current I(C) of Nb(3)Sn strands as function of a strain is very important for large high field superconducting magnet applications such as the superconducting outsert coil of the series-connected hybrid at the NHMFL and the ITER magnets. Apparatuses for measuring I(C) versus longitudinal strain and transverse stress have been developed and used at the NHMFL. We have characterized the I(C) strain sensitivities of a few candidate strands for the series-connected-hybrid. In addition, I(C) irreversibility strains are measured for the recently developed ITER high J(C) strands. The different strain sensitivities for different strands are discussed.
