Abstract
A current lead assembly for minimizing heat load to a conduction cooled superconducting magnet during a ramp operation is provided. The current lead assembly includes a vacuum chamber having a through hole to enable a retractable current lead having a retractable contact to penetrate within the vacuum chamber. A superconducting magnet is arranged inside of the vacuum chamber and includes a magnet lead. A current contact is arranged inside of the vacuum chamber beneath the through-hole and is coupled to the magnet lead via a thermal connector. The current contact is supported by a thermal isolation support structure coupled to an inside wall of the vacuum chamber. An actuator assembly is provided to contact the retractable contact with the current contact, where connection occurs at ambient temperature inside of the thermal isolation support structure.
