摘要：
This paper reports a 3.5 W at 80 K high-frequency pulse tube cryocooler (PTC), which is developed in the Cryogenic Laboratory of the Chinese Academy of Sciences (CL/CAS). The U-shaped configuration is adopted for the pulse tube refrigerator. Up to now, the high-frequency PTC has reached the lowest temperature of 38.8 K and the cooling capacity is about 3.58 W at 80 K, with the input power of 200 W of the linear motor, and the optimal frequency is about 40 Hz. And also, this paper introduces the necessary analysis on the performance and discusses the approaches to improve the performance. The research is still on the way.
