Abstract

See full text

An apparatus comprising a first component comprised of a first material, wherein the first material has a first thermal contraction property. A second component comprised of a second material, wherein the second material has a second thermal contraction property, wherein the second component has an opening where a portion of the first component is inserted into at room temperature. Wherein the second thermal contraction property is larger than the first thermal contraction property and when at cryogenic temperatures, the first component and second component constrict, wherein the second component constricts more than the first component causing the second component to exert a constricting force on the portion of the first component inserted into the opening of the second component.
