Recently, the steady-state strong magnetic field experimental device developed by the High Magnetic Field Science Center of the Hefei Institute of Physical Sciences, Chinese Academy of Sciences has reached the "peak of science and technology": its hybrid magnet (magnet diameter 32 mm) generates 452,200 Gauss (or 45.22 Tesla) )'s stable magnetic field has set a new world record for similar magnets, becoming the highest stable magnetic field in the world that can support scientific research. The original world record was set by the National High Magnetic Field Laboratory in the United States in 1999. Its hybrid magnet produced 450,000 Gauss, and it has held the record for 23 years.
The steady-state strong magnetic field experimental device is a major scientific and technological infrastructure (also known as a "big scientific device") approved by the National Development and Reform Commission during the "Eleventh Five-Year Plan" period. It includes ten magnets: five water-cooled magnets, four superconducting magnets and one Desk hybrid magnet. Among them, the hybrid magnet is the most technically difficult magnet in the world, and it is also the magnet that can generate the highest stable magnetic field. From a structural point of view, it is composed of an outer "superconducting magnet" and an inner "water-cooled magnet". In 2016, the strong magnetic field team independently developed a hybrid magnet with a central field strength of 400,000 Gauss, ranking second in the world. The team has never stopped pursuing innovation and scaling new heights. After more than five years of intense technical research, the strong magnetic field team innovated the magnet structure, developed new materials, optimized the manufacturing process, and finally achieved a major technological breakthrough. The hybrid magnet of this steady-state strong magnetic field experimental device produced a steady-state strong magnetic field of 452,200 Gauss under a power supply of 26.9 megawatts, reaching the international leading level and becoming an important milestone in the construction of extreme conditions for scientific experiments in my country and even in the development of strong magnetic field technology in the world. .
Steady-state strong magnetic field is an extreme experimental condition required for material scientific research, and is a "sharp weapon" to promote major scientific discoveries. In a strong magnetic field experimental environment, material properties will be regulated, which is conducive to scientists discovering new phenomena of matter and exploring new laws of matter. The world's technological powers have always attached great importance to the construction of strong magnetic field experimental conditions. Currently, there are five stable strong magnetic field laboratories in the world, located in the United States, France, , the Netherlands, , Japan, and China's Hefei Science Island.
The steady-state strong magnetic field experimental device has been running for more than 500,000 machine hours since it was put into operation, providing experimental conditions for more than 170 units at home and abroad, including Tsinghua University , Peking University , University of Science and Technology of China , Fudan University , Nanjing University , Zhejiang University , Zhongke Institute of Physics , Institute of High Energy , Institute of Electrical Engineering, Institute of Semiconductors , device users such as Harvard University in the United States, National University of Singapore, and Max Planck Institute in Germany, and have carried out research in the fields of physics, chemistry, materials, life and health, engineering technology, etc. Cutting-edge research on more than 3,000 topics has resulted in a series of major scientific and technological achievements, such as the first discovery of the three-dimensional quantum Hall effect caused by Weyl orbits, the revelation of the molecular and neural circuit mechanisms by which sunlight exposure improves learning and memory, etc. At the same time, the results derived from the R&D device and many achievements based on device research, such as combined scanning probe microscopy technology, national Class I anti-cancer innovative targeted drugs, etc., have been successfully transformed into real productivity.
The hybrid magnet of the steady-state strong magnetic field experimental device produces the world's highest steady-state magnetic field, which has greatly improved the experimental conditions that support scientists in conducting material scientific research and will play an indispensable role in research on low-power electronic materials key role. As the magnetic field intensity generated by the hybrid magnet increases, its level of open sharing and user service will also be greatly improved, and it will surely become a "sharp tool" to support my country's scientific and technological innovation.
