Abstract
A cryogenic electrical power feed-through assembly includes a contact header assembly. The contact header assembly includes a feed-through body forming a feed-through body cavity disposed therethrough extending between a first opening end to a second opening end. A first contactor plate assembly is disposed at and hermetically seals the first opening end of the feed-through body with a first electron beam weld formed between the first contactor plate and the first opening end. A second contactor plate assembly is disposed at and hermetically seals the second opening end of the feed-through body with a second electron beam weld formed between the second contactor plate and the second opening end. Each contactor plate assembly includes a contactor plate, a plurality of insulative bushings hermetically sealed to and extending through the contactor plate, and a plurality of contact pins hermetically sealed to and extending through the plurality of insulative bushings.
