Biography

Guo Houyang, male, researcher at innovation post. Hefei Institute of "Thousands of people plan" candidate, the National Natural Science Foundation of China Overseas Young Scholars Fund, the National Science Project EAST divertor physics experiment leader, the ITER project special domestic supporting project manager , Members of the ITER boundary and divertor physics expert group.      May 1993, graduated from the University of Quebec, Canada, a doctorate. In 1993 June in Canada magnetic confinement fusion research center in TdeV Tokamak nuclear fusion device divertor ion flux behavior. In January 1994, he was a key member of the core group of the European Nuclear Fusion Research Center, engaged in research on the performance and optimization of nuclear fusion plasma and served as the physical leader of the topic group on "optimization of core plasma performance". In August 1999, he was a senior researcher at the University of Washington in the United States, engaged in the exploration and research of new nuclear fusion energy and was responsible for the field anti-position experiment. In July 2008, he was chief experimental scientist and director of experimental operation department of Tri Alpha Energy New Nuclear Fusion Energy Research and Development Company in the United States. June 2010 was selected the fourth batch of "thousands of people plan."      Dr. Guo Houyang is an internationally renowned divertor and boundary layer physics expert in nuclear fusion energy research. He has extensive experience in experimental theory and simulation. He has achieved outstanding results in the exploration of new ways of fusion energy and has a high international academic status and reputation. His achievements in impurity behavior and physical properties of divertor filters include the discovery that chemical sputtering is an important source of impurities in the JET divertor; the quantitative determination of the sputtering damage to divertor target plates by energetic particle flow and then Deposition. The shielding effect of different divertor geometries on impurities was systematically studied. It was found that the increase of the partial filter resulted in an isotope effect that is beneficial to the fusion performance, that is, the boundary transport barrier could be maintained higher in tritium enriched plasma Pressure, thereby improving the overall nuclear fusion performance. It is further found that the isotope effect comes from the high-energy neutral tritium ion beam implanted into the plasma, revealing the influence of fast particles on the barrier of transport; confirming the influence of impurities predicted by the new classical model on energy transport by experiments, This important relationship between central plasma energy loss and boundary plasmons clearly points out the key to optimizing the H-mode properties of thermions.

Research Interest

 Dr. Guo Houyang's research on controlled nuclear fusion also involves the intersection of different modes of magnetic confinement. In the field of fundamental physics exploring new nuclear fusion energies: A very high state of magnetic confinement plasma with similar tokamak stability was found. He applied a series of theories and research methods of more mature tokamak to anti-positional field research and opened up new ways for nuclear fusion energy. It is found that in a field inversion with a small number of toroidal fields, the large lengthening ratio L / a and the very small aspect ratio R / a enable q to exceed 1 even though the toroidal field is much smaller than the polar field. In the presence of anti-shaped instability in the theoretical analysis of the introduction of the quality factor q. This finding is of great importance to nuclear fusion energy science and plasma science research; the use of rotating magnetic fields enables steady-state current drive with very high (90%) plasma; and the use of "anti-symmetric" rotating magnetic fields The confinement of the magnetic flux lines in the high magnetic confinement system was found. It was found that the rotating magnetic field can control the ubiquitous exchange instability in the plasma very effectively. It was found that the plasma spontaneously formed a relaxation phenomenon in the high plasma state and further promoted Exploration of the Basic Principle of Plasma Relaxation.
