✦ Synopsis

The design and analysis of a low heat leak temperature stabilized column type support is presented. Engineering design formulas have been developed for a three tube composite column which uses the cryostat liquid nitrogen radiation shield as a heat sink. Also, the design concept and method of analysis for the general case using many tubes with or without heat sinks is also developed. These simple structural elements conduct negligible amounts of heat to the supported cold mass and may be designed to shrink, grow, or remain unchanged in height when cooled to operating conditions. The three tube specimen presented herein has a collapse load of 9 000 kg and a heat leak of less than 11 mW.
