Performance boundaries in Nb3Sn superconductors

Superconducting magnets for High Energy Physics, Fusion, Magnetic Resonance Imaging (NMR) and Nuclear Magnetic Resonance, benefit from the extremely high current densities that can be achieved in superconductors compared to normal conducting materials. These magnets are usually constructed starting with a composite wire of typically 1 mm in diameter, in which the superconducting material is embedded in a copper matrix in the form of micrometer scale filaments. The present superconducting workhorse is Niobium-Titanium.
