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. (C) 2008 Elsevier Ltd. All rights reserved.
