Two-stage Gifford–Macmahon microcryogenic system for operation at subhelium temperature

  • Published:
Chemical and Petroleum Engineering Aims and scope

The results of updating series-made model of two-stage Gifford−MacMahon microcryogenic system for lowering the temperature level and raising the refrigeration output are reported. Design solutions have been obtained that helped substantially improve, with minimal modification of the series-made two-stage Gifford–MacMahon microcryogenic system, the characteristics of the system: the refrigeration output at the helium temperature level exceeded 0.7 W and the minimum temperature was 1.66 K, which is a unique outcome for microcryogenic systems.
