      Dang, H. Z.; Wang, L. B.; Wu, Y. N.; Li, S. S.; Yang, K. X.; Shen, W. B.; Fu, H. (Georgia Institute of TechnologyICC Press, 2008-05)
      Large capacity high frequency single-stage coaxial inertance pulse tube cryocoolers have been developed and are becoming mature in SITP/CAS. The main objective of the development is to provide larger low-noise cooling ...
    • Experimental Investigation on a Single-Stage Stirling-Type Pulse Tube Cryocooler Working below 30 K 

      Ren, J.; Dai, Wei; Luo, Ercang; Wang, Xiaotao; Hu, Jianying (Georgia Institute of TechnologyICC Press, 2008-05)
      Stirling-type pulse tube cryocoolers are promising candidates for space application and for cooling HTS devices. Nevertheless, most single-stage Stirling-type pulse tube cryocoolers (SSPTCs) are unable to reach a cooling ...
    • Performance of a Stirling-Type Pulse Tube Cooler for High Efficiency Operation at 100 Hz. 

      Wang, Xiaotao; Dai, Wei; Hu, Jianying; Luo, Ercang; Zhou, Yuan (Georgia Institute of TechnologyICC Press, 2008-05)
      High efficiency pulse tube coolers driven by linear compressors usually operate between 30 Hz and 60 Hz. This article presents the performance of a high efficiency in-line PTC with an operating frequency of 100 Hz. The ...
    • Secondary Pulse Tubes and Regenerators for Coupling to Room-Temperature Phase Shifters in Multistage Pulse Tube Cryocoolers 

      Radebaugh, R.; O’Gallagher, A.; Gary, J. (Georgia Institute of TechnologyICC Press, 2008-05)
      Multistage pulse tube cryocoolers require separate phase shifters for each stage. For sufficiently high frequency and acoustic power, the inertance tube is commonly used for such phase shifting. For Stirling-type, multistage ...
    • Space Micro Pulse Tube Cooler 

      Nguyen, T.; Petach, M.; Michaelian, M.; Raab, J.; Tward, E. (Georgia Institute of TechnologyICC Press, 2008-05)
      The Northrop Grumman space micro pulse tube cooler (micro) is a split configuration cooler incorporating a coaxial cold head connected via a transfer line to a vibrationally balanced back to back linear compressor. The ...
