Prof. DONG Yu-Hui is the Deputy Director of Institute of High Energy Physics, Chinese Academy of Sciences. He is the executive member Biophysics Society of China, the director of Photobiology Committee. Now he is in charge of the construction of beamlines and end-stations of High Energy Photon Source (HEPS), a 4th generation synchrotron radiation facility, as Executive Deputy Manager of the project.
In 1990, he obtained B.S. in Physics in Sun Yat-Sen University (Zhongshan University), Guangzhou, China. He obtained Ph.D. in Physics in Beijing Synchrotron Radiation Facility, Institute of High Energy Physics, Chinese Academy of Sciences, Beijing, China, in 1995. During 1995-2000, he was Post-doctoral Research Associate at Institute of Physics, Chinese Academy of Sciences, Beijing, China and University of Trento, Italy.
In 2001 he became Professor of condensed matter physics in Institute of High Energy Physics, Chinese Academy of Sciences.
Teaching activities have included lectures in MSc and PhD courses and supervising of MSc and PhD theses.
His research activities focus on the methodological research in structure determination of proteins and protein complexes based on synchrotron radiation. The main research fields are:
- The structure-function relationship of proteins and protein complexes by synergic method on synchrotron radiation, e.g., protein crystallography, SAXS, X-ray imaging;
- Methods in structure determination of proteins and complexes;
Professor DONG has authored/co-authored: 3 chapters in books written by teams; about 160 scientific papers in journals and conferences.
He is the reviewer for Nature, Nature Communication, Scientific Report, Nucleic Acid Research Acta Crystallographica Section A: Foundations of Crystallography, Acta Crystallographica Section D: Biological Crystallography, Acta Crystallographica Section F: Structural Biology and Crystallization Communications, Journal of Applied Crystallography, Journal of Physical Chemistry, Journal: Physica B, Solid State Sciences, Chinese Physics Letters; also for proposals applied to National Natural Science Foundation of China; National Basic Research Program of China (973 Program), Ministry of Science and Technology; ECHO Grants - Chemistry in Relation to Biological and Medical Sciences, Netherland.
The progress of the research in material and other fields evokes higher requirements for synchrotron radiation, especially the high brilliance, coherence and high energy X-ray. This kind of hard X-ray would provide the chance to study the structures of real materials under real conditions, as well as the real-time structures with very high spatial, energy and time resolutions.
One of the important tendencies in the development of synchrotron radiation sources is low emmitance. Low emmitance storage rings could provide higher brilliance, which is very important for all kinds of experiments in synchrotron radiation facilities. For example, the emmitance of NSLS-II, a new facility in Brookhaven National Laboratory, is 1.0nmrad. The emmitance of MAX-IV, another new facility in Sweden, goes down to 0.3nmrad. The light source Sirius in Brazil is also a low emmitance machine. Even the existed machines, such as ESRF, APS and SPring-8, have been or will be upgraded to low emmitance ones.
In the meantime, the successful construction of Shanghai Synchrotron Radiation Facility and the great achievements in the research in this facility, inspire the users to build the new and high-performance light sources in China. In the view point of regional factors, the vast in territory of China requires the reasonable distribution of synchrotron radiation facilities which support the scientific and technological research, in order to farthest satisfy the demands of users from different regions.
Based on the above reasons, we are building a new synchrotron radiation facility in the region around Beijing: High Energy Photon Source (HEPS). The designed electron energy of HEPS is 6GeV and the emmitance is lower than 0.1nmrad. This machine can provide the hard X-ray with brilliance higher than 1022ph/s/mm2/mrad2/0.1%BW and photon energy higher than 300keV. Also HEPS keeps the possibility of upgrading to more advanced light source (XERL or diffraction limit storage ring).
One of the main purposes of HEPS is to satisfy the urgent requirements of material sciences, especially the real-time structures of engineering materials under service environment. Certainly, the high brilliance hard X-ray from HEPS can also provide a very good support in other fields of research, such as condensed matter physics, chemistry, environment sciences, life sciences, etc. In Phase I, totally 14 user beamlines will be built for different kinds of research.
The construction of HEPS is going well as planned, even if the outbreak of COVID-19. The civil construction is almost complete, the accelerator and beamlines are in the stage of equipment manufacturing. The whole facility will be in operating at the end of 2025.
