Abstract:Many cryogenic researches and applications require high stability of temperature. Cryostats are especially designed to provide constant cryogenic temperature environments. Improving the temperature stability of cryostats has been attracting more research attentions. This paper reviews recent studies on the cryostats and the strategies on suppression of the temperature fluctuation of cryostats. By comparing the structure, cooling power and cooling performance of the cryostats, the cryocooler cryostats are recommended in cryogenic researches.
