The minimum theoretical refrigerator power for cooling mechanical supports for a cryogenic apparatus is determined with the calculus of variations. A mathematical approach is developed that can be used to evaluate the thermal performance of any mechanical support which has fixed geometry. Four prac

โฆ Synopsis
A small number of refrigerated shields have previously been shown to reduce thermal radiation heat leaks as efficiently as a hundred superinsulated shields. In this paper the use of superinsulation, or even a small number of floating shields, between the refrigerated shields is shown to result in different optimum temperatures and a significant reduction in the total refrigeration power.
