Conductor fabrication for the ITER model coils

The Nb/sub 3/Sn cable-in-conduit 40 kA, 13 T conductors proposed for the next generation ITER tokamak are being tested by the construction of a 600 MJ solenoid and a 80 MJ race track coil. The conductors are being manufactured in a world wide collaboration, with task sharing among the four partners of the ITER project. To date, the qualification and /spl sim/20% of the procurement of the Nb/sub 3/Sn strands is complete. Several hundred meters of dummy copper cable and short lengths of superconducting cable are available. The production of jacket sections is advanced and the two jacketing lines are set up for production. The manufacture of 98 tonnes of cable-in-conduit conductors will be completed in autumn 96.
