A high efficiency hybrid stirling-pulse tube cryocooler
AIP Advances, 2015 This article presented a hybrid cryocooler which combines the room temperature displacers and the pulse tube in one system. Compared with a traditional pulse tube cryocooler, the system uses the rod-less ambient displacer to recover the expansion work ...

Gepta-EX: a multi-channel germanium detector for X-ray absorption fine structure. [PDF]
J Synchrotron RadiatGepta‐EX is a compact seven‐channel high‐purity germanium detector designed to deliver high‐resolution fluorescence X‐ray absorption fine‐structure measurements at photon energies where silicon detectors become effectively transparent. It provides excellent energy resolution across a broad energy range, avoids silicon escape‐peak artifacts, and offers ...

Thermal Design of a Protomodel Space Infrared Cryogenic System [PDF]
Journal of Astronomy and Space Sciences, 2006 A Protomodel Space Infrared Cryogenic System (PSICS) cooled by a stirling cryocooler has been designed. The PSICS has an IR sensor inside the cold box which is cooled by a stirling cryocooler with refrigeration capacity of 500mW at 80K in a vacuum vessel.
