Chinese scientists to do pulsed magnetic field experiments to change the status quo to go overseas
China news agency, Wuhan, April 10 (Ai Qiping and Zhou Qianjin) – Huazhong University of Science and Technology announced 10 days, after six months of hard work, China’s largest pulsed magnetic field experimental device prototype system assembly, commissioning completed. This device is Technical Director, China Academy of Engineering, said Yuan Shi Pan, experimental setup is completed, will change the Chinese scientists to do pulsed magnetic field experiments to go overseas, the status quo.
in the “pulsed magnetic field under the cutting-edge scientific problems,” International Symposium on, Huazhong University of pulsed magnetic field center demonstrates to the Chinese and foreign experts under the magnetic properties of pulsed magnetic field experiments and continuous discharge test. Reporters on the scene, with the technical staff pressed the button, the one million joules of pulse power to the magnet discharge, the control room computer screens blink of an eye on the gentle curve into the steep peaks. Twenty-five ms instant, the device has produced five hundred thousand gauss magnetic field strength, the equivalent of a million times Earth’s magnetic field strength.
“one of my dreams, where true!” Huazhong University of Science and Technology Advisor, 77, “the father of pulsed magnetic field,” Professor Fritz ? Heng Naqi said the demonstration site. This is his seventh visit to Huazhong University of Science, he praised the lab is the world’s most modern pulsed magnetic field laboratories.
According to reports, the prototype system is developed in accordance with the preliminary design of technical solutions, including 1MJ/25kV pulse capacitor type power supply, remote control systems, four short pulse magnets, two scientific experiment stations and two low-temperature systems . After testing, the prototype system to achieve the design specifications, test accuracy than the world’s leading type of lab with the University of Leuven, Belgium.
Pan Yuan academician, scientific research development to date, more need to use extreme conditions to find the unknown world. Research has long confirmed that when the material is in a strong magnetic field, its internal structure may change. Using this technique, for physics, materials, chemistry, medicine and other fields of life and provide a platform for scientific research, such as the medical use of magnetic resonance imaging.
learned that the pulsed magnetic field experimental device is China’s “Eleventh Five-Year” Plan period the construction of major national scientific and technological infrastructures, the Ministry of Education of China’s first state university construction of major scientific and technological infrastructure projects. This project plans to invest over one hundred million yuan, after five years, will become the world’s four pulsed magnetic field of science centers. (End)
