Refresh the world record!I have been maintained by the United States for 23 years before

On the 12th, the reporter learned from the Hefei Material Science Research Institute of the Chinese Academy of Sciences that 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" -its hybrid magnet (32 mm magnetic) generated 45.22 The steady -state magnetic field of Wan Gauz (that is, 45.22 Tesla) refreshes 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.

It is reported that the original world record was created by the National Strong Magnetic Laboratory in 1999. Its mixed magnet produced 450,000 Gaus, which has maintained a record for 23 years.

Steady -state strong magnetic field experimental device hybrid magnet

The steady -state strong magnetic field is an extreme experimental condition required for material science research, and is the "weapon" to promote major scientific discovery. Under the environment of a strong magnetic field, material characteristics will be regulated, which will help scientists to discover new material phenomena and explore new laws of material.

How high is the 452,200 Gaos (ie 45.22 Tesla, 1 Tesla = 10000 Gaussian) magnetic field produced by the hybrid? for instance. The earth's magnetic field is equal to 0.5 Gaussia, and the 452,200 Gauss is equivalent to more than 900,000 times that of the Earth's magnetic field.

Experimental results refresh the world record

The international competition in the field of steady -state and strong magnetic field technology is very fierce. The world's strong country has always attached importance to the construction of strong magnetic field experiments. At present, there are five major steady -state strong magnetic field laboratories in the world, which are distributed in the United States, France, the Netherlands, Japan, and Hefei, China.

Experimental site

As of now, when the device has operated more than 500,000 machines, it has provided experimental conditions for more than 170 units at home and abroad. In the fields of physics, chemistry, material science, life science, pharmacy, engineering technology and other fields, more than 3,000 topics have been carried out, and a series of major scientific and technological achievements have been achieved. For example , Reveal the molecular and neural circuit mechanisms that improve the learning and memory, and so on. At the same time, relying on the many results derived from the device, such as scanning micro -imaging technology, the development of national -type innovation targeted drugs, etc., it has successfully transformed into real productivity and actively serves economic and social development.

The steady -state strong magnetic field experimental device hybrid magnetic refresh world records, which also laid an important foundation for another large scientific device planned by the strong magnetic field science center- "strong light magnetic integration experimental facility".
