Thermodynamic property relations for liquid 3 He-4 He mixtures at saturated pressure based
on experimental measurements of the specific heat are determined. The relations are valid …

A thermodynamic model of a 3 He-4 He cold cycle dilution refrigerator with no actively-
driven mechanical components is developed and investigated. The refrigerator employs a …

A recipe is presented for interpreting non-invasively the transport processes at work during
relaxation of a cylindrical, superfluid-filled vessel, after it is accelerated impulsively and then …

Current state of the art sub Kelvin Superfluid Stirling Refrigerators and Pulse tube Superfluid
Refrigerators use multiple bellows pistons to execute the cycle. These types of displacers …

A novel sub-Kelvin refrigeration cycle is introduced in this work. The magnetically driven
superfluid pulse tube refrigerator (MSPTR) could provide cooling at temperatures below 200 …

We describe the development and experimental results of a proof of concept Superfluid
Magnetic Pump in this work. This novel low temperature, no moving part pump can replace …

Continuous and efficient sub-Kelvin cooling for uninterrupted operation of cutting-edge
detectors, both in space and on the ground, is critical for top performance in many NASA …

Current state of the art particle and photon detectors such as Transition Edge Sensors (TES)
and Microwave Kinetic Inductance Detectors (MKID) use large arrays of sensors or detectors …

ABSTRACT A concept for a superfluid pulse tube refrigerator that uses a 3He-4He mixture
as the working fluid is described. The proposed pulse tube refrigerator will be driven by a …

Large superconducting magnets are used in various space science applications (that is,
particle detectors designed to search for antimatter, dark matter, and the origin of cosmic …
