ABSTRACT:
An elongated cryogenic envelope is comprised of a plurality of sections each including an outer tube and a coaxial inner tube spaced therefrom by a support means. The outer tubes of each section are joined together to form a continuous outer tube. The inner tubes, however, are unjoined so that fluid can flow therebetween, but an expansion means is affixed to at least one of the inner tubes to separate the vacuum chamber from the fluid passing through the space between the inner tubes.
