This paper conducts systematic theoretical analyses of a hybrid cryocooler composed of a
four-stage Stirling-type pulse tube cryocooler (SPTC) and a Joule-Thomson cooler (JTC), in …

The paper considers experimental data on the dynamics of superfluid helium in a U-shaped
cylindrical channel. An experimental cell and a methodology for investigations, parameter …

A cryogenic system has been designed and tested that reaches a temperature below 1.1 K,
with an rms temperature stability of 25 μ K. In this system a commercial pulse-tube …
