1. Magnetic phenomenon is one of the basic phenomena of matter. Scientific research has long confirmed that when matter is in the magnetic field, its internal structure may change, so the magnetic field has been a very useful tool for the study of physics and many other disciplines. Strong magnetic field, like ultra-low temperature and ultra-high pressure, is listed as one of the most important extreme conditions in modern scientific experiments. It can be divided into steady-state strong magnetic field and pulse strong magnetic field, and its corresponding generating device can be divided into steady-state strong magnetic field device and pulse strong magnetic field device. Under the condition of extreme magnetic field, the structure of matter will change. This technology can provide a platform for scientific research in the fields of physics, materials, chemistry, life and medicine, such as magnetic resonance imaging technology used in medicine [2].
2. The first batch of major national science and technology infrastructure projects of colleges and universities directly under the Ministry of ecation, the pulsed high magnetic field experimental device, laid the foundation in Huazhong University of science and technology on the 25th. According to the introction, this project will become one of the world's four major high magnetic field scientific research centers juxtaposed with the pulsed high magnetic field laboratories of the United States, France and Germany, It lays an important foundation for Chinese scholars to obtain significant original innovative achievements in many basic research fields. At the beginning of 2007, the national development and Reform Commission officially approved Huazhong University of science and technology and Hefei Institute of material science, Chinese Academy of Sciences to jointly undertake the construction task of high magnetic field experimental device. Among them, Huazhong University of science and technology will construct the pulsed high magnetic field experimental device with an initial investment of 120 million yuan and a construction period of five years.
3. There are four of the same level in the world, including Huake, which is the first in China. Needless to say, the peak field strength seems to be the first in the world
4. At present, the world's largest strong magnetic field laboratory record is 91.4t, which was set in June 2011 by the hochfeld laboratory in Forschungszentrum Dresden rossendorf, Germany
the 90t is the second highest, set by the national high magnetic field laboratory in Los Alamos. The 90t is the former world record
relying on Huazhong University of science and technology, the national high intensity pulsed magnetic field Science Center (Preparatory) has made an important breakthrough. In November 2011, the first domestic double coil pulsed magnet developed by the center successfully achieved a magnetic field strength of 83 Tesla, which once again set a new record for China's pulsed magnetic field strength, making China's non-destructive magnetic field strength rank third in the world and first in Asia, It surpasses Japan, which is the third largest country in the world
as far as we know, there are only two materials that can barely keep the 100 Tesla coil electromagnet intact: one is carbon fiber, and the other is the high-strength synthetic fiber now used in bulletproof vests. At least, Dresden's high magnetic field laboratory uses these two materials, and they are often close to the point of fragmentation in their work
therefore, it is very difficult to seek greater breakthroughs in the short term!
5. There are two national science centers in Chinese Universities:
-
National Science Center for material service safety (Beijing University of science and Technology)
National Science Center of pulsed high magnetic field (Huazhong University of science and Technology) -
-

We will build a scientific experimental test system for electric transport, magnetic properties, magneto-optical properties, pressure effect, and extremely low temperature to provide an ideal research platform for scientific research in condensed matter physics, materials, magnetism, chemistry, life and medicine under high pulsed magnetic field. After completion, the device will be open to domestic surgeons
6. Under the framework of the science and technology cooperation agreement between the governments of China and Belgium, the project of "research and development of super intense pulsed magnetic field" was funded by the governments of both sides twice in 2002 and 2007. The project was jointly implemented by Huazhong University of science and technology and the University of Leuven in Belgium. Based on the implementation of the project, Huazhong University of science and technology has established the laboratory of pulsed high magnetic field. Each year, Leuven University of Belgium sends experts to work in China to guide the construction of the laboratory, and receives researchers selected by Huazhong University of science and technology to study in the European high magnetic field laboratory. Both sides have carried out a lot of cooperative research work
Huazhong University of science and technology and the University of Leuven jointly developed the pulse magnet design software pmds2.0, which was adopted as a magnet design tool by the European "denuf" project
from 2003 to 2004, Huazhong University of science and technology pulsed high magnetic field laboratory became the Key Laboratory of the Ministry of ecation, and developed the pulsed high magnetic field device with the highest magnetic field intensity in China. After that, Huazhong University of science and technology, based on the construction of the Key Laboratory of the Ministry of ecation of the people's Republic of China and supported by the science and technology cooperation between the Chinese and Belgian governments, declared the national major science and technology infrastructure of the pulsed high magnetic field and obtained the approval
at the beginning of its construction, Huazhong University of science and technology's pulsed high magnetic field laboratory aimed at the world's advanced level, supported by international scientific and technological cooperation, and aimed at building high-level pulsed high magnetic field devices. After a short period of five years, the scientific research level has achieved a leap forward development, and the magnetic field intensity has doubled, which has laid a solid foundation for the construction of world-class pulsed high magnetic field device. At the same time, the university has established a close cooperation with the world's major pulsed high magnetic field laboratories, which has been recognized by the world's pulsed high magnetic field academia. In the next five years, Huazhong University of science and technology is expected to build a world-class pulsed high magnetic field laboratory, develop pulsed magnets of more than 80 Tesla, impact the world record of pulsed magnetic field intensity, and make China reach the world advanced level in the field of pulsed high magnetic field
7. Young, but already "extremely intelligent"; After ten years of traveling abroad, he still kept a low profile. On December 28, 2011, the reporter met "legendary" Li Liang for the first time at the national pulsed high magnetic field Science Center (Preparatory). His simple clothes and simple style made people relax
Li Liang was born into an intellectual family in Jingzhou City, Hubei Province“ When I graated from college, I was thinking about my future, just like the current college students. At that time, a speech by Pan Yuan, academician of the Chinese Academy of engineering, made me interested in the research of magnetic confinement controlled thermonuclear fusion. Later, I chose to go to the Institute of plasma physics of the Chinese Academy of Sciences to continue my study. " Li Liang said
at that time, foreign scientific circles paid more and more attention to the research of strong magnetic field, while the research in this field in China was just beginning. In 1985, the Institute of plasma physics of the Chinese Academy of Sciences was recruiting young scholars to enter the field“ The research institute is built on an island, so far away from the city, and the conditions are relatively difficult. " Li Liang said. Out of interest in the new subject, he insisted on staying
in 1987, Li Liang was selected as the first batch of graate students in the history of the Chinese Academy of Sciences to transfer to "Zhibo". The "Zhibo" ecation lasted for five years. It is reasonable to say that in 1990, he would get a doctor's degree. Unexpectedly, it was not until 1997 that he got his doctorate in a foreign country. Seven years later than originally expected
now speaking of the past, Li Liang seems indifferent: "when he was a graate student, the state prepared to develop its own ht-u Tokamak device, but for various reasons, the state decided to import a complete set of devices from abroad, and the project was forced to step down."
Li Liang only got his master's degree in Fusion Engineering in 1988 e to the failure of the project to proce research results
such a good seedling should not be wasted. In 1991, Li Liang was allowed to study abroad. Professor Fritz henazi of the University of Leuven, Belgium, has long enjoyed the reputation of "father of pulsed strong magnetic field" in the world. After Li Liang sent his application materials to Professor Fritz henazi, he soon got a reply
in this way, Li Liang went to Belgium to start a new career of pursuing students
8. Who said it was a strong magnetic field, don't answer if you don't know. Microwave belongs to the telecommunication system, which has nothing to do with the strong magnetic field. The microwave center is mainly divided into the South first floor and the detection station. How about employment? Just ask the Department of telecommunications.
9. The pulsed high magnetic field center of Huazhong University of science and technology was founded in 2005. It is mainly engaged in the research of pulsed high magnetic field technology and scientific experiments under the environment of pulsed high magnetic field. At present, the center undertakes the construction task of the national major scientific and technological basic project - pulsed high magnetic field experimental device.

10. At the school of physics, University of Leuven, Li Liang studied physics courses that he had not systematically studied in the Department of electrical engineering in the past, while participating in the research work of his tutor“ In recent years, I have been responsible for the design, manufacture, experiment and maintenance of 67 magnets. From 1993 to 2000, I basically completed the pulsed magnets of the national high intensity magnetic field laboratory of the United States, the pulsed high intensity magnetic field laboratory of Germany and the pulsed high intensity magnetic field laboratory of Australia. " Speaking of these, Li Liangcai, who has always been modest and prudent, shows his pride
it is important to know that the international well-known high magnetic field laboratories in Belgium, the United States, Japan, Germany, the Netherlands, Australia and other countries come to Li Liang for research and development. Li Liang, a student, had developed a high-performance pulsed magnet with a magnetic field strength of 74 Tesla. "This was the highest record in the world at that time."
before he graated, many big companies, universities and research institutions competed to hire him. Finally, Li Liang chose the national high intensity magnetic field laboratory of the United States, which is the most professional counterpart of his own. Until now, this laboratory is also the world's number one high magnetic field laboratory. In 1998, he again created the world's highest field strength of pulsed magnetic field of 79 Tesla at that time
after three years of basic research in the laboratory, Li Liang became interested in the application of pulsed high magnetic field. From 2000 to 2007, Li Liang has been a senior engineer in the global research center of General Electric (GE) Company in the United States. He has been engaged in the research of high magnetic field, integral magnetization technology, magnetic resonance imaging (MRI) and high temperature superconcting motor, and his research achievements are at the international leading level
