Description

To meet the growing demand for compact cooling solution required by superconducting electronic devices, we developed a two-stage 2K GM cryocooler with cryostat system which can provide 0.1 W / 20 mW cooling power at 45 K / 2.3 K for first and second stage under no-load condition. Nevertheless, with several innovative technologies applied, the total length of expander cylinder is shortened to under 70 % compared with the smallest conventional 4K GM cryocooler. In this paper we will present the design methods including material selection and structure design with detailed explanation which have been confirmed by both simulation and experimental results. The research results have been achieved by “Development of a Compact Superconducting Single Photon Detector System for Photon-Quantum Information and Communication”, the National Institute of Information and Communications Technology (NICT), JAPAN.
