Abstract
Recently, the development of Nb3Al conductors has progressed rapidly with the aim apply them to fusion magnets. In general, the critical current density of Nb3Al is insensitive to strain (or stress) in comparison with that of Nb3Sn. This property is useful in the construction of high-field and large magnets; particularly, fusion magnets. The Nb3Al strands are copper-stabilized multifilamentary composites produced using a jelly-roll process. In this paper, the status of Nb3Al conductor development and the characteristics of the Nb3Al conductor are reported.
