Abstract

Certain in-orbit experiments, which are presently in the planning stage, have stringent low-temperature environmental requirements. In the case to be considered here, it is necessary to maintain a cylindrical interior having a volume of several cubic feet at a spatially uniform temperature. The magnitude of the temperature should not exceed 30°K. In addition, small electronic components must be kept at a constant temperature of 5°K or less. The required lifetime of these environments is approximately one week in orbit. This paper discusses some of the problems encountered in designing systems to meet these requirements in low gravity and proposes tentative solutions to the problems.
