Status Report On A 0.6m Bore Nb3sn, Wind And React, Cicc Solenoid

Ansaldo and ENEA have carried out the design of a Nb3Sn solenoid, 0.6 m bore, wound with a CICC conductor and manufactured with the "wind and react" technique. The solenoid will be tested in the SULTAN facility (PSI,Villigen,CH) where, in operation condition, will be subjected to a magnetic field of 12 T on the inner radius, with a current of 6 kA. An accurate description, including critical energy calculation, quench behaviour and stress analysis are reported in the paper. In order to check the technological aspects of the design, Ansaldo got experience on a 0.6 m bore, 21 turns, model coil.
