The forced cooled Nb3Sn superconductor and its magnet

The coil is a 0.6 m outer diameter solenoid, made up of eight double pancakes which will be tested in a forced cooled test facility that has been already constructed. The hollow conductor consists of a couple of Nb3Sn flattened cable in the center, a couple of Oxygen Free Copper stabilizer and the outside welded sheath. Some features of this conductor are as follows; the cooling mechanism by forced cooled supercritical helium and the high current capacity. The experimental results of this conductor and its magnet will be presented in this paper.
