Niobium tin sheet for superconducting magnets

摘要

A method to provide large sheets of Nb3Sn superconducting material suitable for use as a superconducting gradient shield in a magnetic resonance imaging system magnet by heating an anodized Nb-1 Zr sheet, tin dipping and reacting the sheet, and subsequently quenching the sheet in a purged atmosphere to provide an improved time constant and lowered Jc heating when used in a superconducting magnetic field.
