Patent ID: 7371968

Claim:
A detachable connection for a superconducting cable in a system having electric elements, at least a portion of said system and elements being maintained in a sub ambient temperature and pressure environment, comprising: a first superconducting cable having a first portion and a second portion, said first portion being in said system environment, said second portion being outside said system environment; a first thermal transition providing a barrier between said system environment and outside said system environment, said first thermal transition being sealed and leak tight with said System environment, said second portion of said first superconducting cable extending through said first transition barrier to the outside, a first interface between said first superconducting cable and said first thermal transition being sealed and leak tight; a second superconducting cable having a first portion and a second portion, said first portion of said second superconducting cable being in said system environment, said second portion of said second superconducting cable being outside said system environment; a second thermal transition providing a barrier between said system environment and outside said system environment, said second thermal transition being sealed and leak tight with said system environment, said second portion of said second superconducting cable extending through said second transition barrier to the outside, a second interface between said second superconducting cable and said second thermal transition being sealed and leak tight; wherein the first superconducting cable and the second superconducting cable are electrically connected.
