Development of 0.1W at 4K GM cryocooler

摘要

The 0.1W at 4K GM cryocooler system, SRDK-101D, is newly developed. The cryocooler produces the cooling capacity of 0.1W at 4.2K at the end (second) stage of its two cooling stages. It is the lowest cooling capacity model with the minimum power consumption among 4K GM cryocooler lineups of SHI. The cryocooler is also a user friendly model driven by commercial AC1OOV single phase from the wall. In this paper, design concept, basic structure and fundamental performance of the cryocooler are discussed.
