Abstract

The requirements for ultrareliable miniature cryocoolers with affordable price is growing up for the military, space and commercial Infrared applications. For surveillance application operating 24 hours around the clock, a MTTF in the range of 20 000 hours is targeted today by the potential users. To reach this goal, a technical breakthrough is necessary and a combination of an ultrareliable linear drive compressor based on flexure bearings and a Pulse Tube coldfinger is proposed. The progress on miniature pulse tube and the development status of the compressor assembly is presented. Keywords: Ultrareliable cryocooler Pulse Tube, flexure bearings, affordable price.
