Abstract :
Significant system advantages result if the superconducting levitation and propulsion coils can be operated at temperatures higher than 4.2 K, which can be achieved with cable-in-conduit conductors (CICCs) using Nb/sub 3/Sn and supercritical helium as the working fluid. The authors compare the relative advantages of NbTi and Nb/sub 3/Sn for this application. They also discuss the system aspects surrounding the selection of operating temperature, current density and number of modules. The features of a suitable CICC Nb/sub 3/Sn conductor which has been manufactured are described.<>
