Temperature and magnetic field dependence of the critical current density for a mass-produced Nb3Al multifilamentary strand fabricated by a jelly-roll method [for ITER].

Temperature and magnetic field dependence of the critical current density for a mass-produced Nb3Al multifilamentary strand fabricated by a jelly-roll method [for ITER].

JAERI has been developing jelly-roll processed multifilamentary Nb3Al-Cu strands for the toroidal field (TF) coils of fusion tokamak machines since 1986, in cooperation with Sumitomo Electric Industries. One ton of mass-produced strands were successfully manufactured for the 13 T-46 kA Nb3 Al insert...
