Coaxial Stirling pulse tube cryocooler with active displacer [PDF]
, 2020 Coaxial pulse tube cryocoolers are the configuration of choice as they allow better access to the cold head. Hence, a previously built and tested in-line pulse tube cryocooler which uses an active displacer for phase control has been modified into a ...

Study on Iron Loss in Two Kinds of Moving-magnet Linear Motors [PDF]
, 2012 Linear motors are widely used in cryogenic fields to drive Stirling-type cryocoolers. Generally the Joule heat loss associated with copper lead is considered as the main loss in motors while the iron loss is ignored at a lower frequency operation, not ...

Numerical study of a cryogen-free vuilleumier type pulse tube cryocooler operating below 10 K
IOP Conference Series: Materials Science and Engineering, 2017 This paper presents a numerical investigation on a Vuilleumier (VM) type pulse tube cooler. Different from previous systems that use liquid nitrogen, Stirling type pre-coolers are used to provide the cooling power for the thermal compressor, which leads to a convenient cryogen-free system and offers the flexibility of changing working temperature range
