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. 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." Kuang Guangli, the academic director of the Strong Magnetic Field Science Center of the Hefei Research Institute of the Chinese Academy of Sciences. Gauss, the record has been maintained for 23 years. The breakthrough of Hefei's "Science Island" steady -state 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. In the fields of 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. At the same time, the results of the research and development devices derived from the research generated by the research and development devices have been successfully transformed into real productivity.

This major breakthrough has effectively enhanced the experimental conditions that support scientists to carry out material scientific research, and will play an indispensable key role in research on low -power electronic materials. With the improvement of the magnetic field intensity generated by the mixed magnets, its open sharing level and user service level will also be greatly improved, which will surely become a major "weapon" to support my country's scientific and technological innovation.

There is also a key figure behind "45.22" -35

The backbone of the 35 -year -old scientific research team creates a world record

The "material secrets" under the strong magnetic field are rich and charming. Hefei's "world -class" steady -state strong magnetic field will inevitably bring more new discoveries, revealing more new laws of substances. The reporter was informed that the backbone of the scientific research team of this world record was a group of young people with an average age of 35.

Strong magnetic field with "magic"

Like extremely low temperature and ultra -high pressure, a strong magnetic field is one of the most important extreme conditions of modern scientific experiments. Under the "magic power" of the strong magnetic field, the material often changes in wonderful changes. For example, some superconductors can instantly become insulators, and some ordinary materials will become new conductors.

"Scientists can find their changes and study their changes by observing the substances in the strong magnetic field." Kuang Guangli said that the higher the strength of the magnetic field, the better the research conditions provided. It's like the multiple of the microscope, which will be enlarged by 100 times to see more abundant and unique content than zooming in 10 times.

In recent years, many users, including the Hefei Research Institute of the Chinese Academy of Sciences, Tsinghua University, Peking University, China University of Science and Technology, etc., have achieved a series of major scientific and technological achievements. Erxin, the molecular and neural circuit mechanisms that improve the sunlight and improve learning memory. At the same time, the results of the research and development devices derived from the research produced by the research and development of the device, such as the combined scanning probe microscopic technology, the national type I anticancer innovation targeted drugs, etc., successfully transformed into real productivity.

Today, Hefei's steady -state strong magnetic field has become the highest steady -state magnetic field that can support scientific research worldwide. It will bring more new discoveries in the fields of physics, chemistry, materials, life health, engineering technology, and reveal more. New laws of multi -material.

"For example, in the field of materials science, many people in the industry are currently paying very much attention to low -power electronic materials. This material can produce electronic devices such as low -power integrated circuits and has very important application prospects. Now use our steady state The magnetic field is very hoped to "explore 'out of this material. Once there is a major discovery, it will promote huge advancement of the electronics industry." Kuang Guangli said that the team will use the strong magnetic field device to be built well and continue to continue. Support cutting -edge scientific exploration. "We will also further promote the development of the magnetic field technology itself, strive to make extreme conditions with higher magnetic fields, and create a stronger 'weapon' for scientific exploration." Kuang Guangli said that at present, the strong magnetic field science center has also planned to build another one. Large scientific device- "Strong Light Magnetic Integrated Experimental Facilities", target construction includes a series of magnetic devices with the world's highest steady -state magnetic field strength represented by 55T hybrid magnet and 36T superconducting magnets.

The average age of the scientific research team is 35 years old

Behind the important scientific indicators of "45.22", there is also a number worthy of attention -35. This is the average age of the backbone of the scientific research team that created the world record.

"Under the leadership of their predecessors, these young people have carried up the burden and provoked the beams. The leading scientific and technological data plus a vibrant scientific research team, the two brought stronger confidence to our scientific and technological development development "Said Huang Chenguang, Secretary of the Party Committee of the Hefei Research Institute of the Chinese Academy of Sciences.

Fang Zhen, an associate researcher at the Hefei Research Institute's strong magnetic field science center and a member of the water -cooled magnetic technology research team of the strong light magnetic pre -research project, was 33 years old. In 2018, he graduated from the University of Science and Technology of China and joined the "Science Island" strong magnetic field team.

"We recognized this incident, and then looked at the gap between the" world first "of the previous" first "." Fang Zhen said that after entering the team, the predecessors not only did academic guidance of young people, but also thought about Teach everyone in way so that everyone can reach the state of "scientific research" faster.

The high magnetic field is as high as jumping. Over the years, a large number of explorations and breakthroughs have been made from the design of the magnetic field structure, the selection of materials, to the processing process, etc.

Fang Zhen recalled that in an experiment, everyone found that the resistance of the coil failed to meet the expectations, and everyone immediately took the spirit to strive to find the reason at the fastest time. "Basically, in addition to sleeping and eating every day, I am doing this." Fang Zhen said that in the end, everyone took a week to successfully solve this problem. "This is just a small problem in our technical breakthrough. In fact, on every issue, everyone is in a state of‘ open horsepower ’and try our best to do your part."

Make major deep -level improvements in structural design; apply new insulating materials to improve the stability of the magnet; adopt higher accuracy of laser processing technology to better meet the design requirements ... For the higher magnetic field, the strong magnetic field team will conduct A series of breakthroughs.

"This process is not easy. We have experienced many failures, and now we feel more successful." Chen Siyue, a researcher at the Hefei Research Institute of the Academy of Sciences Hefei Research Institute, and the chief engineer of the strong light magnetic pre -research project, said that every time it improved, it has been improved. However, I found that the experiment failed to meet the standards, but it would be a bit frustrated, but leading this group of young people, everyone can quickly "get up and fight", continue to find problems, analyze, and find ways. Breakthroughs have successfully built this highest steady -state magnetic field that can support scientific research worldwide.
