A Fast Cool-Down J-T Minicryocooler
Geist and Lashmet1 in 1959 discussed design criteria for miniature open cycle Joule-Thomson refrigerators and developed an early working model. Subsequently, several other models have been developed2 and their utilization appears to be widespread. Despite deficiencies such as low efficiency and the requirement of a high-pressure gas source, J-T minicryocoolers have the advantages of compactness, low cost, and the ability to achieve low temperatures very quickly. Accordingly, they have attracted much attention.
