Development toroidal field conductor for NET

A description is given of the ECN (Netherlands Energy Research Foundation) conductor concept for use in the Next European Torus Program and the manufacture of different test components. A discussion of the testing of these test lengths demonstrates the feasibility of this concept for the industrial production of the toroidal-field conductor. It is concluded that the fabrication of short cable lengths is now possible, but for the fabrication of long cable lengths, more powerful equipment it is necessary. Laser-beam welding is also discussed for welding the conduit of the TF conductor without damaging the interior.
