Patent Images
1. An elongated cryogenic envelope comprising:
- an inner tube;
an outer tube generally coaxial with said inner tube;
a refrigeration tube positioned intermediate said inner and outer tubes;
means for supporting said inner tube within said outer tube and said refrigeration tube intermediate said inner and outer tubes, at least a portion of the volume between said inner tube and said outer tube providing a vacuum chamber for holding a vacuum;
said means for supporting said inner tube within said outer tube including;
a high-thermal-conductivity ring surrounding said inner tube said ring being positioned intermediate said inner and outer tubes; and
a positioning means for positioning said ring intermediate said inner and outer tubes, said positioning means comprising at least one low-thermal-conductivity spoke extending between said surrounding ring and said outer tube; and
wherein said at least one refrigeration tube is supported by a radially extending portion of said ring.

Abstract
An elongated cryogenic envelope includes a support-spacer for locating a plurality of refrigeration tubes at selected radial and circumferential locations within a vacuum chamber formed between inner and outer coaxial tubes. The support-spacer includes a high-thermal-conductivity ring surrounding the inner tube and a plurality of hollow epoxy-fiberglass, titanium-tipped spokes extending between the outer tube and the high-thermal-conductivity ring surrounding the inner tube.
