ITER TF conductor insert coil manufacture

A single layer Toroidal Field Conductor Insert (TFCI) coil for testing at 46 kA in the 13 T background magnetic field generated by the Central Solenoid Model Coil (CSMC) of the International Thermonuclear Experimental Reactor (ITER) has been manufactured by a collaboration of Russian scientific-industrial institutions. The report contains a brief description of the technique and tooling used for the 1152 Nb₃Sn strand, thin-wall Ti jacket, 45-m length cable-in-conduit conductor manufacturing, its wounding into the coil, end bending, terminal joint preparation, heat treatment in a high-vacuum electrical oven, insulation and transfer into the spiral grooves from inside of a cylindrical stainless steel mandrel, and vacuum-pressure impregnation with epoxy.
