  • High temperature superconducting current leads for superconducting magnets
    Patent number: 7372273
    Abstract: An electrical current lead assembly for ramping a superconducting magnet includes a vacuum vessel wall that has a first side exposed to an atmospheric pressure and a second side exposed to a vacuum pressure. A pool wall extends from the first side of the vacuum vessel wall and forms a dam region. A first conductor is affixed to and sealingly penetrates the vacuum vessel wall and has a first portion extending into the dam region. A second conductor is affixed to and sealingly penetrates the vacuum vessel wall and has a first portion extending into the dam region. A superconducting magnet on the second side of the vacuum vessel wall has a first low temperature superconducting (LTS) lead and a second LTS lead. A first superconductor electrically connects the first conductor to the first LTS lead, and a second superconductor electrically connecting the second conductor to the second LTS lead.
