The Gamma Gage II Portable Cryostat/Dewar is a high-performance liquid nitrogen cooling system designed for use with high purity germanium (HPGe) radiation detectors. Engineered for portable and field-based gamma spectroscopy, this system allows users to “bring the detector to the sample,” making it ideal for applications such as waste assay, site characterization, nuclear safeguards, and in-situ radiation measurements. The system integrates both the cryostat and LN₂ dewar into a compact, transportable unit, providing reliable cooling performance with flexible holding times depending on operational needs. Users can choose between two dewar configurations: All-attitude design: Prevents LN₂ spillage regardless of orientation Multi-orientation (MOD): More compact and lightweight, with flexible positioning options With built-in safety features such as automatic high-voltage shutdown and high count-rate indication, the Gamma Gage II ensures safe and stable detector operation even in demanding environments. This makes it an ideal solution for laboratories and field teams requiring portable, reliable, and high-performance cooling for HPGe detectors.
