Contents

Beijing Synchrotron Radiation Facility is a major synchrotron radiation facility located in Beijing and operated by the Institute of High Energy Physics (China), serving researchers across China and international partners such as institutions in Japan, Germany, United States, and United Kingdom. The facility supports experimental programs in fields including materials science, biophysics, chemistry, and environmental science through beamlines developed in collaboration with organizations such as the Chinese Academy of Sciences, Peking University, Tsinghua University, and the National Natural Science Foundation of China. It functions within networks of large-scale facilities including the European Synchrotron Radiation Facility, the Advanced Photon Source, and the SPring-8 project while contributing to national initiatives like the National Key R&D Program of China.

Overview

Beijing Synchrotron Radiation Facility is a user-oriented accelerator complex comprising an electron linear accelerator injector, a booster ring, and a 2.5 GeV storage ring, established to provide high-brightness synchrotron radiation in the infrared, ultraviolet, soft X-ray, and hard X-ray regimes for experiments by researchers from Peking University, Tsinghua University, Fudan University, Zhejiang University, and international groups from CERN, the Max Planck Society, and the Lawrence Berkeley National Laboratory. The facility delivers photon beams to beamlines used in structural biology projects associated with Protein Data Bank, crystallography groups linked to International Union of Crystallography, and spectroscopy initiatives related to American Chemical Society and Royal Society of Chemistry communities.

Construction began in the mid-1980s with support from the Chinese Academy of Sciences, the Ministry of Science and Technology (China), and international advisers linked to Stanford Linear Accelerator Center and Brookhaven National Laboratory, leading to first light in 1988 and progressive upgrades coordinated with programs at Japan Atomic Energy Research Institute and the Deutsches Elektronen-Synchrotron. Subsequent modernization phases involved collaborations with groups from Imperial College London, University of Oxford, Harvard University, and industry partners like Siemens and General Electric to improve machine reliability, optics, and insertion devices inspired by designs at Diamond Light Source and SOLEIL.

The complex uses a 2.5 GeV storage ring with a circumference and lattice informed by designs from National Synchrotron Light Source II and the SPring-8 family, fed by a linear accelerator and booster modeled on systems at DESY and Argonne National Laboratory. Key technical components include insertion devices such as undulators and wigglers, vacuum systems influenced by standards from CERN and the Institute of High Energy Physics (China), radiofrequency systems comparable to those at KEK and SLAC National Accelerator Laboratory, and beam diagnostics drawing on expertise from Max Planck Institute for Plasma Physics and Lawrence Livermore National Laboratory. The optical laboratories house monochromators and focusing mirrors developed with suppliers experienced by European XFEL and Swiss Light Source projects.

Beamlines cover hard X-ray diffraction and imaging, soft X-ray spectroscopy, infrared microscopy, and time-resolved techniques used by researchers from Peking University, Tsinghua University, Chinese Academy of Sciences, Fudan University, and visiting groups from University of Tokyo, University of Cambridge, Massachusetts Institute of Technology, and Columbia University. Research themes include macromolecular crystallography contributing to structures deposited in the Protein Data Bank, catalysis studies connected to American Chemical Society journals, electronic-structure investigations relevant to IEEE publications, and environmental aerosol analysis aligned with projects from the World Meteorological Organization and United Nations Environment Programme.

Administration is led by the Institute of High Energy Physics (China) under frameworks associated with the Chinese Academy of Sciences and funding from the Ministry of Science and Technology (China) and the National Natural Science Foundation of China, with collaborative agreements and user programs in partnership with Peking University, Tsinghua University, Fudan University, international laboratories such as CERN, KEK, Brookhaven National Laboratory, and consortia involving the European Synchrotron Radiation Facility and APS. Industry partnerships and technology transfer link the facility to companies and agencies including Siemens, GE Healthcare, Thermo Fisher Scientific, and national innovation initiatives like the Made in China 2025 strategy.

User access operates through peer-reviewed proposal calls coordinated with university partners Peking University and Tsinghua University and international user offices modeled after systems at Diamond Light Source and Advanced Photon Source, providing training programs in accelerator physics and beamline techniques with instructors from Institute of High Energy Physics (China), visiting scientists from Max Planck Society, Imperial College London, and data-management practices interoperable with repositories like the Protein Data Bank, archives maintained by the Chinese Academy of Sciences, and data policies informed by standards from European Synchrotron Radiation Facility and National Science Foundation (United States).
