Abstract
Structure modification tests of a staged pulse tube refrigerator have been carried out for the purpose of increasing the performance and sim plicity. The influence of operation parameters on cooling effect has b een tested. To reach liquid helium temperatures by a two-stage pulse t ube refrigerator, a double-orifice configuraton is utilized for enhanc ing the phase shift effect. Experimental results and a discussion are also presented. (C) 1997 Elsevier Science Ltd.
