Research Profile

Jia Qika currently works as a research professor and doctoral supervisor at the National Synchrotron Radiation Laboratory, University of Science and Technology of China (USTC). Jia was admitted to the Department of Modern Physics, USTC in 1977 and graduated in February 1982 with a B.S. degree. Jia received his M.S. and Ph.D. from the Department of Modern Physics, USTC in December 1984 and May 1990 respectively. In his research, Prof. Jia established a linearly polarized measuring device which helped measure the photon polarization correlation in electron-positron annihilation, and the research results he obtained disputed those elicited by his Western counterparts.
     Since 1985, Prof. Jia has been working at the National Synchrotron Radiation Laboratory, dedicating himself to research on magnetic field measurement, synchrotron radiation, and free-electron laser successively. He became the deputy head of the research group on storage ring free electron laser in 1993, a project supported by the National High Technology Research and Development Program of China (namely, the “863” Program), being responsible for the main tasks of physical design and experimental study. In 1997, Prof. Jia served as an organizing committee member, invited representative, and one of the executive chairmen of the Third FEL Asian Academic Exchange Conference (Osaka). As of 1997, Prof. Jia was in charge of the new undulators project in the second phase of the construction of the National Synchrotron Radiation Laboratory, which had been satisfactorily completed in 2002. Prof. Jia has been on the council of the Particle Accelerator Society of China since 2000, and on the standing committee of the Chinese National Committee for Synchrotron Radiation since 2003. As of 2003, Prof. Jia has been serving as the general deputy head of the joint research project of “Deep Ultraviolet Free Electron Laser” undertaken by the Shanghai Institute of Applied Physics, the USTC National Synchrotron Radiation Laboratory, and the Institute of High Energy Physics Beijing, in charge of the overall project design and the development of undulators. Since 2005, Prof. Jia has been serving on the Academic Committee of the USTC National Synchrotron Radiation Laboratory. In 2007, he took up the position of chief investigator for the project of “High Brightness Injector” supported by the “985” construction projects. From 2001 and on, Prof. Jia has been teaching the graduate course of “Introduction to Free-electron Laser Physics”. To date, Prof. Jia has authored more than 50 research papers in important academic journals at home and abroad.
