Patent ID: 7372273

Claim:
An electrical current lead assembly for ramping a superconducting magnet, the assembly comprising: a vacuum vessel wall having a first side exposed to an atmospheric pressure and a second side exposed to a vacuum pressure; a pool wall extending from the first side of the vacuum vessel wall and forming a dam region; a first conductor affixed to and sealingly penetrating the vacuum vessel wall and having a first portion extending into the dam region; a second conductor affixed to and sealingly penetrating the vacuum vessel wall and having a first portion extending into the dam region; a superconducting magnet on the second side of the vacuum vessel wall having a first low temperature superconducting (LTS) lead and a second LTS lead; a first superconductor electrically connecting the first conductor to the first LTS lead; and a second superconductor electrically connecting the second conductor to the second LTS lead.
