Major breakthrough!"Science Island" steady -state strong magnetic field refresh world record

On the afternoon of August 12, the Academy of Material Science of the Chinese Academy of Sciences officially released major scientific and technological breakthroughs: the national steady -state and strong magnetic field experimental device developed by the strong magnetic field science center developed by the institute climbed the "peak of science and technology". The steady -state magnetic field of Gauss (ie 45.22 Tesla) refreshed the world record of the same type of magnet, and has become the highest steady -state magnetic field that can support scientific research globally worldwide.

The national steady -state magnetic field experimental device is a major scientific and technological infrastructure approved by the National Development and Reform Commission during the "Eleventh Five -Year Plan" period, including ten magnets: Wutai water -cooled magnets, four superconducting magnets, and a mixed magnet. Among them, hybrid magnets are the most internationally difficult magnetic magnets, and it is also a magnet that can produce the highest steady -state magnetic field.

In 2016, the strong magnetic field team independently developed a mixed magnet of the 400,000 Gaus, ranking second in the world. After 5 years of multi -technical research, the strong magnetic field team innovative manufacturing technology has achieved major technical breakthroughs. The mixed magnet of the national steady -state strong magnetic field experimental device generated 452,200 Gauss's steady -state strong magnetic field under the power supply of 26.9 MW, reaching the international leading level, becoming important for the construction of the extreme conditions of scientific experiments in my country and the development of the world's strong magnetic field technology. milestone.

The strength of the earth's magnetic field is about 0.5 Gauss, and the 452,200 Gauss is equivalent to more than 900,000 times the Earth's magnetic field. In the environmental environment of a strong magnetic field, material characteristics will be regulated, which is conducive to the discovery of new material phenomena and exploring new material laws. It is a "weapon" that promotes major scientific discovery. Since 1913, 19 Nobel Prize in the world has been related to the strong magnetic field. The strong magnetic field is also known as the "cradle of the Nobel Prize." At present, there are five major steady -state strong magnetic field laboratories, which are distributed in the "Science Island" in the United States, France, the Netherlands, Japan, and Hefei, China.

"The higher the magnetic field, the more opportunities to discover science." According to Kuang Guangli, the academic director of the strong magnetic field center of the Hefei Research Institute of the Chinese Academy of Sciences, the original world record of the same type of magnetic was created by the National Strong Magnetic Laboratory in 1999. It has maintained a record for 23 years. The breakthrough of Hefei's "Science Island" steady -state and strong magnetic field marks that it has become the highest steady -state magnetic field that can support scientific research globally worldwide.

The steady -state and strong magnetic field experimental device in Hefei was approved on May 19, 2008. When more than 500,000 machines were operated, they provided experimental conditions for more than 170 units at home and abroad, and achieved a series of major scientific and technological achievements, such as For the first time, the three -dimensional quantum quantum effect caused by the Waier orbit, the molecules and neural circuit mechanisms that revealed sunlight irradiation to improve learning memory. At the same time, the results of the research and development devices derived from the research produced by the research and device.

Kuang Guangli introduced that the major scientific research breakthrough this time will effectively enhance the experimental conditions that support scientists to carry out material science research. It will play an indispensable key role in research in low -power electronic materials and other studies. A major "weapon" of innovation.
