For the ITER project a large dipole magnet is needed for a conductor test facility. Original conductors for the superconducting ITER magnets will be qualified by measuring their current characteristics in the background field of this dipole. To insert the test samples the magnet is built out of 2 saddle shaped race track coils

The superconductor strands are inside a jacket of stainless steel and are cooled by a forced flow of liquid helium at a temperature of 4 K - a so called cable in conduit conductor (CICC).

After winding of the coil the supersonductor needs to be reacted by a heat treatment cycle at about 650° C.
