Air Liquide space cryocooler systems

Abstract After successful developments these last 3 years, AL/DTA is now in position to propose two pulse tube cryocooler systems for space applications in the 40–80 K temperature range. The two pulse tube cryocoolers are yet qualified against stringent thermal and mechanical environmental constraints. AL/DTA also develops associated Cooler Drive Electronic at QM level implementing launch locking and vibrations cancellation. This paper presents these complete cryocooler systems available for space applications.
