    • Why High-Frequency Pulse Tubes Can Be Tipped 

      Swift, G. W.; Backhaus, S. (Georgia Institute of TechnologyICC Press, 2008-05)
      The typical low-frequency pulse-tube refrigerator loses significant cooling power when it is tipped with the pulse tube’s cold end above its hot end, because natural convection in the pulse tube loads the cold heat exchanger. ...
