How many synchrotron radiation sources in China?

Synchrotron radiation light source has a wide range of applications, including materials science, life science, energy science and other fields of research. For example, in the field of materials science, synchrotron radiation sources can be used to observe the microstructure and dynamic processes of materials, and to study the physical and chemical properties of materials. In the field of life science, synchrotron radiation source can be used to study the structure and dynamics of biomolecules and explore the mysteries of life processes. In the field of energy science, synchrotron radiation sources can be used to study photocatalysis, photochemistry, solar cells and other energy conversion and utilization processes.

Synchrotron radiation sources can be divided into three generations.

The first generation of synchrotron radiation sources produced soft X-ray and far-ultraviolet spectra, such as the Beijing Synchrotron Radiation Facility (BSRF).

The second generation of synchrotron radiation sources produce soft X-ray and vacuum ultraviolet spectra, such as the Hefei Synchrotron Radiation Facility.

The third generation of synchrotron radiation sources produce X-ray lasers and extreme ultraviolet lasers, such as the Shanghai Synchrotron Radiation Facility (SSRF).

The fourth generation synchrotron radiation light source (HEPS), that is, the high-energy synchrotron radiation light source, was established in Huairou, Beijing, and is also a major national science and technology infrastructure in the "13th Five-Year Plan". It is expected to be delivered in 2025. By 2022, there are more than 50 synchrotron radiation light sources in use worldwide.

In short, synchrotron radiation light source is a very important scientific research facility, which can provide high-energy and high-brightness radiation light source and provide strong support for scientific research.
