An Experimental Investigation of Pulse Tube Refrigeration Heat Pumping Rates
Pulse tube refrigerators have been under development at Syracuse University since 1962. These efforts have resulted in the construction of units that have achieved 124°K in one stage and 79°K in two stages from room temperature. Another single stage unit operating from 65°K achieved 30°K. Several unique features and reasonably good efficiency make pulse tube refrigeration particularly well suited for certain cryogenic cooling applications.
