Sunpower公司与Gedeon Associates合作，在美国宇航局戈达德太空飞行中心的小企业创新研究（SBIR）资助下开发单级和两级脉冲管制冷机。开发围绕使用高效率，低成本的线性压缩机，太阳能已经采取了制造水平的M87斯特林制冷机。主要目标是证明在77K下使用单级脉冲管冷头的有效冷却。对直列式和U形管两种结构的单级脉冲管冷头进行了制造和试验。用两级冷头在30 K下冷却是获得多级经验的第二个目标。第二级设计为单级U形管配置的附加组件。所有的设计都采用了惯性管作为声学调谐装置。最终目标是确定线性压缩机驱动的脉管制冷机的商业潜力，以及它们是否可以与Sunpower M87斯特林制冷机在成本上竞争。单级脉管制冷机在77 K时以100 W的电输入功率实现5.2 W的热升，而两级脉管制冷机在30 K时提升260 mW，同样是100 W的电输入。
Sunpower, Inc. and Gedeon Associates partnered to develop single and two-stage pulse tube cryocoolers under Small Business Innovative Research (SBIR) funding from NASA Goddard Space Flight Center. The development centered around using the high-efficiency, low-cost linear compressor that Sunpower has already taken to the manufacturing level with its M87 Stirling cryocooler. The primary goal was to demonstrate efficient cooling at 77K with a single-stage pulse tube cold head. Both in-line and u-tube configurations of single-stage pulse tube cold heads were fabricated and tested. Cooling at 30 K with a two-stage cold head was a secondary goal undertaken to gain experience with multi-staging. The second stage was designed as an add-on component to the single-stage u-tube configuration. All designs implemented inertance tubes as acoustical tuning devices. The ultimate objective was to establish the commercial potential of linear-compressor driven pulse tube cryocoolers and whether they could be cost competitive with the Sunpower M87 Stirling cryocooler.High efficiency was demonstrated with the single-stage pulse tube cooler achieving 5.2 W of heat lift at 77K with 100 W electrical input power, and the two-stage pulse tube cooler lifting 260mW at 30K, again with 100 W electrical input.
