Summary:A 40-T hybrid magnet under construction at the High Magnetic Field Laboratory of the Chinese Academy of Sciences will use cable-in-conduit conductors for its superconducting outsert. The design necessitates the use of high current density ( J c ) hbox Nb 3 hbox Sn strands ( J c greater than or equal to hbox 2100 Unknown character hbox A / mm 2 at 12 T/4.2 K). The high J c restacked-rod-processed hbox Nb 3 hbox Sn strand from Oxford Instruments Superconductor Technology was selected as one of the candidate strands. A series of tests was carried out to qualify the strand performance. Tests mainly included magnetization and critical current measurements as a function of axial strain, magnetic fields, and temperature. The test results are presented and discussed.
