Structure modification tests of a staged pulse tube refrigerator have been carried out for the purpose of increasing the performance and simplicity. The influence of operation parameters on cooling effect has been tested. To reach liquid helium temperatures by a two-stage pulse tube refrigerator, a double-orifice configuration is utilized for enhancing the phase shift effect. Experimental results and a discussion are also presented.
