Abstract

This paper presents an overview of the Cryogenic Thermal Storage Unit (CRYOTSU) flight experiment. CRYOTSU is developed from a series of reflown Cryogenic Test Bed (CTB) flight experiments and incorporates design, integration, and testing techniques for cryogenic systems. Some of the applications described in this paper include: reducing vibration induced by cryogenic refrigerators; mounting the experiments without introducing parasitic heat leaks; selecting thermally conductive and isolation interface materials that would meet the requirements and perform over the temperature range of 55 to 300 K; supporting experiments structurally via kevlar cable suspension straps; developing a beryllium thermal storage unit with dissimilar metals; and testing in 1g in preparation of the flight experiment
