| Abstract: | In the fields of infrared detection and other high-tech technology,many components need to work at low temperatures to reduce the thermal interference and improve the sensitivity,thereby increasing the reliability and working life of the device.Currently there is no domestic research on liquid helium temperature throttling cryocoolers,while this study was carried out in some countries and achieved impressive results.The principle and the structure of J-T throttling was introduced,then the current applicatio... |
