Abstract
A High Temperature Superconductor, HTS, magnet comprising a coil formed of nested concentric windings. Each winding comprises HTS material. The HTS magnet further comprises a conductor element comprising an electrical contact surface through which to supply electric current to a portion of at least one of the windings. The surface provides electrical contact between the conductor element and an axial edge of the coil substantially around the path of the at least one of the windings.

A High Temperature Superconductor, HTS, magnet comprising:
- a coil formed of nested concentric windings wound around an axis of the coil, each winding comprising HTS material;
- and
- first and second conductor elements each comprising respective electrical contact surfaces through which to supply electric current to, or receive electric current from, a portion of a respective at least one of the windings, each electrical contact surface providing electrical contact between the respective conductor element and an axial edge of the coil at least partially around the respective at least one of the windings, the electrical contact surface of the first conductor element being located closer to the axis than the electrical contact surface of the second conductor element, whereby electrical current supplied to the coil through the first conductor element circulates around successive windings of the coil before being received by the second conductor element, or vice versa.
A High Temperature Superconductor, HTS, magnet comprising:
- first and second coils, each coil formed of nested concentric windings, each winding comprising HTS material;
- and
- first and second conductor elements, each conductor element providing an electrical connection between the first and second coils, and each conductor element comprising:
- a first electrical contact surface through which to transfer electric current to or from a portion of at least one of the windings of the first coil;
- and
- a second electrical contact surface through which to transfer electric current to or from a portion of at least one of the windings of the second coil,
- wherein the first conductor element is located radially outwards from the second conductor element and each electrical contact surface provides electrical contact between the respective conductor element and an axial edge of the respective coil at least partially around the path of the at least one of the windings.
