• Continuously Variable Inertance Tubes for Pulse Tube Refrigerators 

      Pfotenhaue, J. M.; Steiner, T.; Qiu, Limin (Georgia Institute of TechnologyICC Press, 2008-05)
      The efficiency and cooling power of pulse tube refrigerators are highly dependent on the phase angle between the mass flow and pressure waves used to produce cooling. Inertance tubes are commonly used to set the phase angle ...
