Abstract

The advanced two-stage stirling cooler has been developed for the cryogenic system of next space missions, SPICA, NeXT, ASTRO-G promoted by JAXA. In order to meet the cooling requirements of these missions, improvement of cooling performance and mechanical reliability is required based on the existing two-stage stirling cooler with cooling capacity 0.2W at 20K by power input 90W, which is operated on the infrared astronomical satellite AKARI (ASTRO-F) launched in 2006/2/22. This paper describes the cooling capacity evaluation test by simulating contamination of the working gas and mechanical attrition reduction by flat-spring-supported displacer for development of the advanced two-stage stirling cooler.
