Superconducting Magnets for Fusion Applications

Fusion magnet technology has made spectacular advances in the past decade; to wit, the Mirror Fusion Test Facility and the Large Coil Project, However, further advances are still required for advanced economigal fusion reactors. Higher fields to 14 T and radiation-hardened supercgndugtors and insulators Will be necessary. Coupled with high rates of nuclear heating and pulsed losses, the next-generation magnets will need still higher current density, better stability and quench protection. Cable-in-conduit gonductors coupled with polyimide insulations and yetter steels seem to be the appropriate path. Neutron fluences up to 1019 neutrons/cm2 in niobium tin are achievable, In the future, other amorphous superconductors could raise these limits further to extend reactor life or decrease the neutron shielding and corresponding reactor size.
