China’s " artificial solar " access to more than 60 seconds steady-state high confinement mode plasma discharge of new energy for 2 minutes to understand China’s artificial solar full superconducting tokamak nuclear fusion experimental device. According to Xinhua news agency, Hefei, November 2 Xinhua (reporter Cai Min) 2 reporter learned from the Hefei Institute of Physical Science.CAS, the national science and Engineering Institute of plasma physics for artificial sun "experimental device EAST recently in the eleventh round of physical experiment and was a major breakthrough, steady high constraint mode plasma discharge over 60 seconds. EAST has become the world’s first experimental device to achieve steady state high confinement mode operation time to reach the order of magnitude of the Tokamak nuclear fusion. The magnetic confinement fusion of senior experts, Japan Naka Nuclear Fusion Research Institute of advanced plasma physics research department director Yu Kamada that on the future of the International Thermonuclear Experimental Reactor (ITER) plan has important significance. It is one of the basic operation modes of ITER to realize the high confinement mode plasma discharge under the conditions of pure RF heating and tungsten divertor. 2012 EAST physics experiment has created a world record of 32 seconds high confinement mode. In recent years, EAST has completed the upgrade of auxiliary heating, tungsten divertor plasma physics, diagnosis system, overcome the problem of the key technology of heating and current drive, distributed parameter measurement, in-depth study and solve a series of problems of physical radio wave coupling, high confinement plasma stability control, under the condition of low momentum heating and current drive for transport, and laid a solid foundation for long pulse steady high confinement mode plasma. The experiment team won the EAST for more than 60 seconds of steady high confinement mode plasma discharge, not only in the plasma parameters, performance and maintenance time constraint length overall, significantly more than the 2012 results, but also realizes the non inductive current drive (i.e. steady state) completely. It is understood that the ITER will be led by the RF low momentum injection operation mode and the active water cooling tungsten divertor structure. EAST is the only one of the two superconducting tokamak with the characteristics of long pulse, and its steady-state operation mode will provide important reference for ITER and future nuclear fusion reactor.相关的主题文章:
