Abstract This paper describes the design, construction, and testing of a two-stage pulse tube cooler that can simultaneously provide 2W of cooling at 35K and 20W of cooling at 85K. This cooler, which was designed for space application, is light weight, power efficient and has long life. The two stage cold head is driven by a TRW second generation flexure bearing compressor. The 35K cold block and the 85K cold block are designed in a parallel configuration to minimize interference among the stages. Cooler test data are presented for a range of cooling temperatures and cooling loads.
