On the 12th, the reporter learned from the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences that the national steady-state strong magnetic field experimental device developed by the strong magnetic field science center of the academy has climbed to a "scientific peak" - its hybrid magnet (magnet diameter of 32 mm) produced 45.22 The steady-state magnetic field of 10,000 Gauss (ie 45.22 Tesla) has set a new world record for the same type of magnet, and has become the highest steady-state magnetic field that can support scientific research on a global scale.
It is reported that the original world record was created by the National High Magnetic Field Laboratory in the United States in 1999, and its hybrid magnet produced 450,000 Gauss, which has been maintained for 23 years.

Steady-state strong magnetic field experimental device hybrid magnet

Steady-state strong magnetic field is an extreme experimental condition required for material science research and a "sharp weapon" to promote major scientific discoveries. In the experimental environment of strong magnetic field, the properties of matter will be regulated, which is beneficial for scientists to discover new phenomena of matter and explore new laws of matter.
How high is the 452,200 Gauss (ie, 45.22 Tesla, 1 Tesla = 10,000 Gauss) magnetic field generated by the hybrid magnet of the Hefei Science Island Steady-State Strong Magnetic Field Experimental Device? for instance. The earth's magnetic field is about 0.5 gauss, and 452,200 gauss is equivalent to more than 900,000 times the earth's magnetic field.

The experimental results broke the world record

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

Experimental site

Up to now, the device has been running for more than 500,000 machine hours, providing experimental conditions for more than 170 units at home and abroad. In the fields of physics, chemistry, materials science, life science, pharmacology, engineering technology, etc., he has carried out cutting-edge research on more than 3,000 topics, and achieved a series of major scientific and technological achievements, such as the first discovery of the three-dimensional quantum Hall effect caused by the Weyl orbit. , reveal the molecular and neural circuit mechanism of sunlight exposure to improve learning and memory, and so on. At the same time, relying on a number of achievements derived from the device, such as scanning microscopy imaging technology, national class I innovative targeted drug development, etc., it has been successfully transformed into real productivity on the spot, actively serving economic and social development.
The hybrid magnet of the steady-state strong magnetic field experimental device broke the world record, and also laid an important foundation for another large scientific installation planned and constructed by the Strong Magnetic Field Science Center - "Strong Opto-Magnetic Integrated Experimental Facility".
