Lockheed Martin has been developing pulse tube systems principally for spacecraft operation for several years. Major emphasis in our pulse tube development has been on improving the thermodynamic efficiency, since other benefits such as low vibration, enhanced reliability, and reduced cost are well established.

    We have developed a pulse tube cooler which provides 2.4 W at 60 K and 4.7 W at 80 K, achieving PV specific powers of 22 WAV at 60 K and 12 W/W at 80 K, with a no-load temperature of 32 K. This system consists of an in-line pulse tube cryocooler, our flight-qualified, flexurebearing, clearance seal compressor, and our flight-qualified electronic controller.
