Description

On the base of a conventional 4K Gifford-Mcmahon (GM) cryocooler, we developed a new 2K GM crycooler system which can provide considerable cooling capacity and yet being highly compact in physical size. A series of experiments were operated to confirm and show the cooling characteristic and cooling capability of this new system. It will be shown that under no-load condition the lowest temperature reached about 2.2K on the exterior surface of the second stage and temperature oscillation displacement was less than ±20mK. Detailed cooling load-map and cooling-down curve will also be introduced in this paper. The research results have been achieved by "Development of a Compact Superconducting Single Photon Detector System for Photon-Quantum Infomation and Communication", the National Institute of Information and Communications Technology(NICT), Japan.
