Abstract
Abstract This invention relates to thermal busbar assemblies in a cryostat dual penetration for refrigerated superconductive magnets. Such structures of this type, generally, allow heat to be conducted from the refrigerated superconductive magnet to the refrigeration cold head while isolating the magnet from the vibration created by the cold head.
