报告摘要: The cryogenic system for the atmospheric vertical interferometric detectors on FY-4 satellite includes a Stirling cryocooler, a radiant cooler, a cryogenic heat pipe and some flexible thermal links, etc. These cryogenic elements were integrated together in order to decrease the background radiation and maximize the sensitivity with high efficiency and high reliability. This presentation summarizes the cryogenic integration design, technical challenges, as well as its testing results on earth and performance in space. |
