Fully bonded internal-tin, niobium-tin (Nb3Sn) conductor development at Oxford superconducting technology

Niobium-tin conductors are the class of conductors which allow the fabrication of superconducting magnets that generate over 9 T at 4.2 K and 12 T at 1.8 K. Oxford Superconducting Technology makes a wide range of niobium-tin conductors, One such conductor is a fully bonded internal tin, Nb3Sn composite, The process for the manufacture of the fully bonded Nb3Sn conductor is described, The process is applicable to conductors for high current applications and applications requiring low AC losses. Results for both classes of conductors are reported.
