BEIs involvement in cryocoolers began with a corporate sponsored project in 1991 to develop a closed-cycle Joule-Thomson cooler for a high-temperature-superconductivity application.After achieving limited success with a mixed gas refrigerant, the company leveraged its expertise in linear compressor technology to develop a miniature Stirling-cycle refrigerator for IR detector cooling.
The first miniature cooler designed for 150mW capacity at 78K has been well received in the infrared user community1.BEI has recently enhanced the performance of this cooler by as much as 30%2.In this paper, the qualification of this cooler to the Military Standard is discussed in detail.
