• An Oil-Free Compressor for Gifford McMahon Cold Heads 

      Caughley, A. J.; Meier, J. (Georgia Institute of TechnologyICC Press, 2008-05)
      Industrial Research Ltd (IRL) has developed a novel metallic-diaphragm pressure wave generator technology for large high-frequency (30-60 Hz) pulse tube cryocoolers. A diaphragm pressure wave generator, using a conventionally ...
    • Pulse Tube Cooler with Remote Cooling 

      Raab, J.; Maddocks, J. R.; Nguyen, T.; Toma, G.; Colbert, R.; Tward, E. (Georgia Institute of TechnologyICC Press, 2008-05)
      Space pulse tube coolers are very efficient, but like all regenerative high frequency Stirling and pulse tube coolers, the cold head needs to be located near the compressor in order to minimize the input power to the cooler. ...
