摘要：

Nb3Al/Cu multifilamentary strands fabricated by the Jelly-roll process, and cable-in-conduit conductors have been developed for fusion magnets. The recent strand has achieved a high critical current density of 800 A/mm(2) (12T, 4.2K) with a feasible heat treatment condition for coils or conductors. The improved strands have were also confirmed to good bending and tensile strain tolerance. A cable-in-conduit Nb3Al superconductor with 1152 strands was also developed. It has a titanium conduit an center tube, conforming to the current design for ITER magnets.
