Electromagnetic analysis of the ITER Toroidal Field Coil Insert properties

In the framework of design and development of the International Thermonuclear Experimental Reactor (ITER) Toroidal Field (TF) Coils, a 45 m conductor winding has been manufactured by the Russian Home Team: the Toroidal Field Coil Insert (TFCI). It was tested in the JAERI facility (Naka, Japan) under various field and temperature conditions. The work presented here concerns the analysis of the electromagnetic behavior of the TFCI using a model developed at CEA. Our work focuses in particular on all observations related to voltage variation with temperature: current sharing temperature (T/sub CS/), n-value, and modeled strand behavior inside conductor.
