The Application of Commercial Materials to the Construction of Small Superconducting Magnets

Part of the Advances in Cryogenic Engineering book series (ACRE, volume 17)


Superconducting magnets are being constructed by industry and by national laboratories in a wide range of sizes and types, from bubble chamber magnets storing many megajoules of energy to very small magnets storing only a few hundred joules of energy. A demarcation exists between the character of the superconductor used in large magnets and that of the material used for small magnets; the difference between them lies in the operating current densities. For reasons of economy, the current density in the windings of all types of superconducting magnets should be as high as possible. But in small magnets, storing typically less than 200 kJ of energy, compact high current density windings alone are competitive. It is this type of winding, as contrasted with the cryostatically stable windings of very large magnets, that is considered here.
