Design and implementation of a non-magnetic cryogenic multi-conductor vacuum feedthrough

Research output: Contribution to journalArticlepeer-review

Abstract

A common issue for experiments requiring very low magnetic fields on vacuum and cryogenic systems is how to deal with the control of magnetic properties of electrical contacts. We describe the design and implementation of a generic sixty-four pin non-magnetic cryogenic vacuum feedthrough capable of disconnecting contacts on both sides of the vacuum boundary.
