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.  |
