Joule-Thomson cryostat cooling system

Our miniature Joule-Thomson (JT) cryostats offer a compact rapid cooling capability for infrared systems. Eaton’s current production cryostats are dual-flow designs with a temperature-sensing bellows capsule. This technology allows the system to have an initial high flow period to rapidly cool down the focal plane, followed by a reduced flow period to maintain the temperature for the mission duration.

The miniature JT cryostat is a high-performance cryocooler suitable for infrared seekers for missile platforms. Historical systems include anti-ground, air and armor programs as well as missile interceptors.
