One kind of LTS magnet is made up of NbTi wire wound around a cylindrical core. The NbTi wire contains a high proportion of copper, which is necessary for thermal stabilization of the magnet. Conventionally, the NbTi wire used in the windings have an insulated coating, even though the use of non-insulated windings is known to improve thermal stability by allowing the stabilizing effect of copper to be shared between adjacent wires. Nevertheless, insulated wires were selected because magnets with non-insulated windings suffer from a delay in charging and increased resistive losses compared to conventional magnets. This invention describes a magnet design utilizing partially insulated windings that mitigates these problems while retaining most of the thermal stability benefits associated with the non-insulated design. This novel design has the potential to reduce the consumption of liquid helium -- an increasingly expensive commodity -- during the manufacturing process, and to produce lighter-weight magnets.
