More Information
Summary:A current lead arrangement for supplying current to a superconducting magnet coil, comprising a current lead and a cryogenic refrigerator. The current lead comprises a first section of low temperature superconductor (LTS) wire, joined to a second section of a high temperature superconductor (HTS) material, in turn joined to a third section of a resistive material. The cryogenic refrigerator comprises a first cooling stage and a second cooling stage. A lower end of the third section and an upper end of the second section are thermally linked to the first cooling stage, a lower end of the first section is thermally and electrically connected to the superconducting magnet coil.
