National major scientific and technological infrastructure "steady -state strong magnetic field experimental device" achieved major breakthroughs

Xinhua News Agency, Hefei, August 12 (Reporter Xu Haitao and Chen Nuo) Reporters learned from the Hefei Material Science Research Institute of the Chinese Academy of Sciences that on August 12th, the national major scientific and technological infrastructure "steady -state strong magnetic field experimental device" achieved major breakthroughs and created strong creation fields The 452,200 Gauss's steady -state strong magnetic field surpassed the world record of 450,000 Gaussian steady -state strong magnetic field that has been maintained for 23 years. The expert group composed of a number of academicians of the Chinese Academy of Sciences and academicians of the Chinese Academy of Engineering believes that the results have reached the international leading level.

Strong magnetic field is an extreme experimental condition exploring the frontier of science. It has an irreplaceable role in discovering new phenomena and promoting new technologies. Since 1913 About 20 related results won the Nobel Prize.

The steady -state and strong magnetic field experimental device is a national major scientific and technological infrastructure established during the "Eleventh Five -Year Plan" period of the National Development and Reform Commission. In 2017, it passed the national acceptance and officially put into operation. Countries with steady -state and strong magnetic fields.

The Institute of Material Science of the Chinese Academy of Sciences is the construction legal person unit of the steady -state and strong magnetic field experimental device. The University of Science and Technology of China is a co -construction unit. After years of independent innovation in the scientific research team, on the basis of building a world -class steady -state strong magnetic field, it has continuously innovated the magnetic structure and optimized the manufacturing process. On August 12, it successfully created a record high of 452,200 Gaos, refreshing the world record of the same type of magnet.

"How strong is 45.22 million Gauss? The earth's magnetic field is about 0.5 Gaussia, and the new record is equivalent to more than 900,000 times the earth's magnetic field." Kuang Guangli, the academic director of the strong magnetic field science center of Hefei Material Sciences Institute of Chinese Academy of Sciences It can be seen more clearly than zooming in. The stronger the magnetic field, the more helpful to the internal structure of the substance, and provides better conditions for the discovery of natural laws and developing new technologies for human beings.

Ye Chaohui, an academician of the Chinese Academy of Sciences, said that the realization of 452,200 Gaus means that the ability of humans to control the magnetic field has reached a new height, making scientists see more accurate and clearer when doing research.

It is understood that since the operation of the steady -state strong magnetic field experimental device is put into use, it has now operated more than 500,000 machines, providing experimental conditions for more than 170 science and education institutions at home and abroad, and supporting scientific researchers There are more than 3,000 cutting -edge studies in technology and other fields to obtain a series of important scientific research breakthroughs.
