| 摘要 |
The present invention discloses multi-component gas mixtures adapted to provide condensed phase cryogenic refrigerants with normal boiling points below about 80° K. for cooling sensor device components. Exemplary gas mixtures generally include 19-40% Ar and 20.1-80.5% Ne. Open-loop Joule-Thomson systems in accordance with the present invention may be suitably adapted (with varying relative mass ratios of cryogenic gas mixtures) for cooling sensor devices to temperatures between 27° K. (100% Neon) and about 80° K. (0% Neon).
