Design of a 0.6-m bore wind-and-react 12-T, 6-kA, Nb/sub 3/Sn magnet

Design concepts for a Nb/sub 3/Sn wind-and-react (W/R) magnet, wound with a cable-in-conduit conductor, are presented. The magnet is designed to operate at approximately 6 kA, generating a maximum field of 12 T over a 0.6-m bore. The design of the forced-flow-cooled cable-in-conduit conductor, the winding principles, the heat exchanger effect in the magnet, and the stress analysis on the coil and conductor are reported and discussed.
