SPIE-DSS 2014 – Adaptive vibration reduction on dual opposed piston free displacer Stirling cooler

In a Stirling-type pulse-tube cooler with a dual-opposed piston compressor, the residual vibration exported by the cooler is primarily a result of residual imbalances between compressor motors. Using an electronic feedback loop [1] and driving compressor motors in a master-slave configuration, the exported force from the compressor can be regulated to negligible levels. This has

ICC 2014 – A 30-50 K dual-stage pulse tube space cooler

A Technical Research Program (TRP) has been granted to the TCBV/CEA/AS consortium for the development, optimization and testing of a cryostat actively cooled by a 2-stage high reliability pulse- tube cryocooler. The interest of this concept is to allow the operation of detectors – for example QWIP or MCT infrared detectors - at lower temperatures,

ICC 2014 – Cost-effective Cryocoolers for Space

In the past two decades, flexure-bearing technology has gained a firm footing in the tactical cryocooler market. This has dramatically increased the reliability of COTS (commercial off-theshelf) systems, making them a viable choice as cost-effective coolers for space missions.  Thales Cryogenics is currently involved in several projects to develop cryocoolers suitable for space applications based
