Observations on Titanium Diffusion in ITT Type Nb Sn Superconductors

Titanium doping has been successfully employed to increase high field J c in internal tin (IT) type conductors. Titanium doping is achieved by placing Nb-47Ti rods within the filament array. Doping occurs during reaction heat treatment as a result of titanium diffusing from the Nb-47Ti source into t...
