走近大国重器 | “看”清太阳磁场的奥秘
Core Viewpoint - The AIMS telescope, a significant scientific instrument for measuring solar magnetic fields, has been officially launched and is expected to enhance understanding of solar phenomena and their impact on Earth [7][15]. Group 1: AIMS Telescope Overview - The AIMS telescope is the world's first mid-infrared solar magnetic field observation device, recently passing acceptance tests and officially entering operation [7][15]. - It is located at an altitude of approximately 4000 meters in the Qaidam Basin, chosen for its optimal observational conditions after extensive site evaluations [14]. Group 2: Scientific Significance - Understanding solar magnetic fields is crucial for deciphering solar phenomena, which have implications for various aspects of life on Earth, including climate prediction and infrastructure safety [10][11]. - The AIMS telescope improves measurement precision from 100 Gauss to 10 Gauss, allowing for more accurate observations of solar magnetic fields [12][13]. Group 3: Development and Innovation - The project took over a decade to develop, with a focus on creating a high-spectral-resolution imaging system that is domestically produced [12][13]. - The team faced numerous challenges, including harsh environmental conditions and the need for self-sufficiency in technology development [20]. Group 4: Collaborative Efforts - The AIMS telescope works in conjunction with space-based solar observation satellites, enhancing the overall efficiency and quality of solar observations through a "ground-space collaboration" approach [17][18]. - This collaboration allows for comprehensive tracking of solar activities and their effects on Earth, contributing to improved space weather forecasting [18].
