With the expansion of scientific research towards the macro level, the deepening towards the micro level, the advancement towards extreme conditions, and the cross cutting efforts towards the comprehensive level, the supporting role of large-scale scientific facilities in scientific research continues to be highlighted. Currently, the construction of large-scale scientific facilities in China is accelerating. Since the beginning of this year, significant progress has been made in the construction of multiple major scientific facilities, involving cutting-edge fields such as material science, life science, and space environment monitoring. They will play an important role in exploring the unknown world, discovering natural laws, and achieving technological changes. The construction of the "super large X-ray machine" is further advanced. The high-energy synchrotron radiation light source has been launched with light coupling, which is a major national scientific and technological infrastructure. The high-energy synchrotron radiation light source (HEPS) officially started with light coupling on March 27th, and the HEPS construction has entered the sprint stage. HEPS, located in Huairou Science City, Beijing, is like an ultra large X-ray machine. By using the high-energy synchrotron radiation generated by HEPS, scientists can "see" the microscopic world and reveal the mechanism of material microstructure generation and evolution. HEPS is the fourth generation synchrotron radiation light source with the highest designed brightness in the world. After completion, it will provide strong support for cutting-edge research in advanced materials, aerospace, biomedicine and other fields. Significant improvement in space weather forecasting and early warning capabilities. The second phase of the Meridian Project passed the national acceptance inspection for major scientific and technological infrastructure. On March 21, the second phase of the Meridian Project passed the national acceptance inspection. This huge space environment foundation "monitoring network" has observation capabilities covering the entire solar terrestrial space circle, which will significantly enhance China's space weather forecasting and early warning capabilities. The short-term changes in the solar terrestrial space environment caused by solar activity are called space weather. High quality monitoring and even forecasting of space weather are of great significance for the smooth operation of high-tech systems such as aerospace and communication. The second phase of the Ziwu Project has built a batch of large-scale monitoring equipment, which has the ability to track the entire chain of ground-based monitoring from solar surface eruptions, interplanetary propagation, to Earth's spatial response. The relevant performance indicators have reached the international leading level. The panoramic revelation of the mysteries of life and the multimodal cross scale biomedical imaging facility passed the national acceptance inspection. The national major scientific and technological infrastructure - the multimodal cross scale biomedical imaging facility - passed the national acceptance inspection on March 21 in Huairou Science City, Beijing. This facility can observe and accurately measure the structure and function of living organisms from molecules to cells, organs, and even individuals, providing imaging omics research methods for complex life science problems and major disease research, and assisting in the research and analysis of major biomedical scientific issues. At present, this facility has attracted dozens of domestic and foreign research teams to settle in, with research involving digital organs, neuroscience, tumor diagnosis and treatment, cardiovascular disease and other fields. China's material science research has added another "weapon" - the comprehensive extreme condition experimental device has passed the national acceptance inspection for major scientific and technological infrastructure. The comprehensive extreme condition experimental device passed the national acceptance inspection on February 26th. This device can create extreme experimental conditions such as extremely low temperature, ultra-high pressure, strong magnetic field, and ultrafast optical field, which will provide strong support for basic research in fields such as material science. Extreme conditions such as extremely low temperature, ultra-high pressure, and strong magnetic field are the "tools" that drive major scientific discoveries. Under these extreme conditions, the properties of matter will be regulated, which is conducive to discovering new phenomena and studying new laws of matter, and can better carry out cutting-edge research such as high-temperature superconductivity and quantum computing. The comprehensive extreme condition experimental device is located in Huairou Science City, Beijing, with performance indicators reaching the international advanced level. It is expected to become an important platform for international scientific and technological exchange and cooperation in the future. The advanced attosecond laser facility, which can "see" electronics clearly, has officially started construction of the national major scientific and technological infrastructure - the advanced attosecond laser facility, which started construction in Dongguan, Guangdong on January 10th. The attosecond is currently the shortest time scale that humans can grasp, with 1 attosecond being only one billionth of a billionth of a second. By using attosecond laser pulses, scientists can track, measure, and manipulate the motion of electrons, much like using a "high-speed camera" to capture the "dynamic images" of electrons. The advanced attosecond laser facility has deployed 10 beam lines and 22 application terminals in Dongguan, Guangdong and Xi'an, Shaanxi. After completion, it will provide strong support for cutting-edge basic research and industrial applications in physics, chemistry, materials, information, biomedical and other disciplines.
