An overview of the IGC Internal Tin Nb 3 Sn conductor

We discuss the current state of the art in the IGC Internal Tin Nb 3 Sn process which routinely is delivering current densities greater than 1 × 10 3 A/mm 2 at 10 Tesla. We focus especially on the conductors suitability for high current density applications such as High Energy Physics and small magnets. Projections are also made as to its suitability for high field applications such as in Fusion. A discussion of the manufacturing process is given with comparisons made to other accepted Nb 3 Sn processes and NbTi. Superconductor characteristics such as filament quality and Nb 3 Sn phase uniformity are compared to those obtained in conventional bronze process.
