Abstract

The 20K-class Double-staged Stirling cooler is a key cryogenic technology for cooling the optical detectors and telescopes of the highly-sophisticated astronomy satellite missions proposed by JAXA, for instance, the x-ray astronomy mission Astro-H(2013) and the cryogenic infrared telescope mission SPICA(2018). Therefore, it is required that the advanced double-staged Stirling cooler with improvement of mechanical reliability and cooling performance will be developed, based on the existing one onboard the first Japanese infrared astronomy mission Akari(2006) with cooling power of 200mW at 20K (90W power input). This paper describes about development status of the advanced double-staged Stirling cooler with cooling performance and long lifetime test.
