| Abstract: | Compared with G-M and Stirling cryocoolers, the pulse tube cooler has the advantages of higher reliability, lower mechanical vibration and magnetic noise and longer lifetime. In has potential to be applied to the cryogenic electronics, space and superconductor cooling. A high-power single stage pulse tube cooler has been designed and constructed. In preliminary experiments, the pulse tube cooler obtained the lowest no-load temperature of 15.4K and cooling power of 6.1W, 21.3W and 37.3W at 20K, 30K and 40K, respectively. The single stage pulse tube cooler with high cooling power at 20K-40K will benefit for superconducting applications. |
