More Information
Summary: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 first end of a current lead contact to remain outside the vacuum chamber and a second end of the current lead contact to penetrate within the vacuum chamber. A vacuum boundary wall is located between the vacuum chamber and the current lead contact. At least one superconducting magnet is arranged inside of the vacuum chamber and includes a magnet lead. A second end of the current lead contact is coupled to the magnet lead via an internal lead. A vacuum cap is removably disposed to sealingly encompass therein the first end of the current lead contact during a first state of operation. The first end of the current lead contact is arranged to contact a power supply during a second state of operation, wherein the contact occurs exterior the vacuum chamber.
