Shanghai Synchrotron Radiation Facility

The Shanghai Synchrotron Radiation Facility is a third-generation synchrotron light source located in Shanghai, designed to provide high-brilliance synchrotron radiation for multidisciplinary research. The facility supports experimental programs across physics, chemistry, materials science, biology, and environmental science, serving domestic and international users from universities, research institutes, and industry.

Overview

The facility comprises a storage ring delivering soft to hard X-ray and ultraviolet beams, an injector complex, and multiple experimental stations. It complements other major light sources such as Advanced Photon Source, European Synchrotron Radiation Facility, SPring-8, Diamond Light Source, and PETRA III in providing advanced capabilities for spectroscopy, diffraction, imaging, and scattering. The campus integrates cleanrooms, sample preparation laboratories, cryogenic systems, and computational clusters to support experiments and data analysis. The facility collaborates with national institutions like Chinese Academy of Sciences, ShanghaiTech University, and Fudan University, and international partners including CERN-affiliated programs, ITER-related materials studies, and bilateral projects with National Institutes of Health, Max Planck Society, and Lawrence Berkeley National Laboratory.

History and Development

Conceived in the 1990s amid China's strategic investments in large research infrastructure, the project built on earlier efforts at facilities such as Beijing Synchrotron Radiation Facility and international exchanges with Stanford Linear Accelerator Center and Brookhaven National Laboratory. Construction began with civil works and magnet procurement influenced by designs from European Synchrotron Radiation Facility engineers and procurement partners like Siemens and Thales. The injector and storage ring commissioning incorporated technologies tested at HASYLAB and DORIS III; first light was achieved after coordinated efforts with Chinese Academy of Engineering advisors and project managers. Subsequent upgrades followed roadmaps similar to Advanced Light Source and ESRF-EBS modernization, enhancing insertion devices and vacuum technology. Major milestones involved joint workshops with Japan Synchrotron Radiation Research Institute and instrumentation exchanges with Paul Scherrer Institute.

Facility and Beamlines

The storage ring operates at beam energies and currents optimized for a suite of beamlines including hard X-ray diffraction, small-angle X-ray scattering, X-ray absorption spectroscopy, and macromolecular crystallography. Beamline designs draw on concepts developed at SOLEIL, ANKA, BESSY II, and Canadian Light Source. Specialized beamlines host techniques such as coherent diffraction imaging inspired by experiments at Linac Coherent Light Source and time-resolved pump–probe studies akin to those performed at FLASH. Instrumentation includes superconducting insertion devices, monochromators similar to those at APS Sector 33, and detectors from vendors collaborating with European XFEL projects. User stations offer cryo-EM sample prep inspired by protocols at EMBL and synchrotron-based tomography comparable to setups at National Synchrotron Light Source II. Ancillary facilities provide laser labs influenced by designs from Max Planck Institute for Biophysical Chemistry and cleanrooms modelled after Riken standards.

Research and Applications

Researchers employ the facility for structural biology studies of proteins implicated in projects with Shanghai Institute of Materia Medica and Tsinghua University, materials characterization for battery research linked to Argonne National Laboratory and Toyota Central R&D Labs, and catalysis investigations in collaboration with Shell and BASF research teams. Environmental science projects address aerosol chemistry paralleling work at NOAA and Scripps Institution of Oceanography, while cultural heritage studies align with conservation programs at British Museum and Metropolitan Museum of Art. Industrial users from Huawei, Chinese Academy of Sciences Institute of Metal Research, and Siemens utilize diffraction and imaging for semiconductor and additive manufacturing development. Cross-disciplinary initiatives include quantum materials research inspired by MIT groups and neuroscience imaging projects with University College London collaborators.

Organization and Funding

The facility is managed under a consortium involving institutions such as ShanghaiTech University, the Chinese Academy of Sciences, and municipal research authorities in Shanghai. Funding sources have included national program allocations comparable to projects funded by the National Natural Science Foundation of China and capital investments modeled on policy frameworks similar to those guiding European Research Council infrastructure. International collaborations and industry partnerships provide supplementary support, mirroring arrangements seen with Wellcome Trust-backed projects and bilateral agreements involving Ministry of Science and Technology of the People's Republic of China counterparts. Governance includes scientific advisory committees with experts formerly affiliated with University of Oxford, Harvard University, Caltech, and ETH Zurich.

Access and User Programs

Access is provided through peer-reviewed proposal calls, user committees, and collaboration agreements similar to access models at ESRF, APS, and Diamond Light Source. Users range from academic groups at Peking University and Zhejiang University to industrial teams from multinational corporations and startups incubated at Zhangjiang Hi-Tech Park. Training programs include beamline schools and workshops held in cooperation with IUCr-affiliated courses and summer schools patterned after CERN training modules. Data management practices follow FAIR principles promoted by organizations such as CODATA and Research Data Alliance, and safety protocols align with standards used at Oak Ridge National Laboratory and Japan Atomic Energy Agency.
