Performance of Joule-Thomson coolers for large diameter focal plane infrared photo-detectors

Joule-Thomson have their unique advantages with respect to compact, light and low cost. It is necessary to explore the performance of Joule-Thomson coolers in order to develop their uses for higher mass and larger diameter focal plane infrared photo-detector. Experiments and analysis are carried on to investigate the parameters of Joule-Thomson coolers. The effects of supply pressures at high ambient temperatures are be focused. It is very helpful to study the performance of Joule-Thomson coolers for large diameter focal plane infrared photo-detector. Deep research on Joule-Thomson coolers will be useful to explore optimization of the Joule-Thomson coolers for infrared photo-detectors.
