On August 30th, the High Energy Photon Source (HEPS), a major national science and technology infrastructure project and China's first high-energy synchrotron radiation source, completed the installation of its accelerator tunnel. This marks the conclusion of the accelerator equipment installation work for the HEPS project and represents a significant milestone in the construction of this facility.

Synchrotron radiation is considered an indispensable tool for cutting-edge scientific research. As the world's brightest light source in the ultraviolet and X-ray bands, it can help scientists observe the internal structure of materials at the microscopic level, ranging from nanometers to micrometers. It is thus regarded as a "super microscope" for scientists.

The HEPS is designed to be one of the world's brightest fourth-generation synchrotron radiation light source facilities. Located in the Huairou Science City in Beijing, the project commenced construction in June 2019 and is scheduled to be completed and operational by the end of 2025. Once completed, it will serve as an essential large-scale scientific platform in China, supporting cutting-edge research in multiple fields and providing technological support for national strategic needs and industrial development.
