Last week, a new delivery of cables was made to the ASG plant in La Spezia (Italy) for the construction of the April DTT toroidal field coil (TFC#03).

The cable was produced by ICAS, an Italian company born from ENEA's experience in the superconductivity field. For its production, 420 Nb3Sn wires and 180 copper wires were twisted; the cable, approximately 1100 m long, is enclosed in a 2 mm thick 316 lN steel sheath. The conductor is able to carry an operating current of 42.5 kA at 4.5 K, in a maximum magnetic field of 11.9 T.

The deliveries for the realization of the TFC#01 and TFC#02 were carried out last January and April, respectively.
