Recently, in the Future Science City of Hefei City, Anhui Province, the National Major Science and Technology Infrastructure Project and Supporting Projects of Hefei Advanced Light Source announced the start of construction, with a planned land area of approximately 656 acres. The first phase of the project is expected to be completed by September 2028.

After completion, it will become an internationally advanced low energy zone synchronous radiation device, enabling China to form an advanced light source system with full energy zone coverage, and accelerating the promotion of Hefei and other places to become world-class photon science research centers and industrial research and development highlands.

It is reported that the proposed Hefei Advanced Light Source is a diffraction limited synchrotron radiation X-ray light source with low energy range, optimized in the soft X-ray band. Its characteristic energy covers the K absorption edge of light elements (carbon, nitrogen, oxygen, phosphorus, sulfur, etc.), making it the most suitable light source for studying the material structure composed of light elements and detecting electronic behavior and their interrelationships in materials.

The National Major Science and Technology Infrastructure Project of Hefei Advanced Light Source is an internationally advanced fourth generation synchrotron radiation device in low energy areas. The brightness and coherence of soft X-rays generated are more than a hundred times higher than the previous generation of light sources. Experimental methods with higher accuracy and sensitivity will be developed in space, time, energy and other dimensions, playing a key role in physics, electronics, information, chemical engineering, materials, life sciences and other fields.

Feng Donglai, an academician of the CAS Member and the general director of the Hefei Advanced Light Source Project, said at the project kick-off meeting that as early as 2006, the National Synchrotron Radiation Laboratory of the University of Science and Technology of China began the research work of the next generation light source. In December 2017, the Chinese Academy of Sciences and Anhui Province jointly invested 356 million yuan to carry out the pre research project of Hefei Advanced Light Source (HALF), which tackled 17 key technologies of the new light source, and successfully passed the process acceptance in January 2021.

In addition, the University of Science and Technology of China has organized and held dozens of domestic and foreign expert demonstrations and user seminars. After extensively listening to expert opinions and clarifying user needs, the construction plan for Hefei Advanced Light Source was finally determined. The plan was officially approved by the National Development and Reform Commission and officially launched on September 20, 2023 Beijing time.

Shanghai Light Source is currently the most advanced light source built in China

Since the 19th century, four types of light sources have had a significant impact on human life and technological development. They are electric light sources, X-ray, laser, and synchrotron radiation light sources.

Shanghai Light Source is a third-generation medium energy synchronous radiation light source with high performance to price ratio, and it is also the most advanced light source built in China at present. Due to the rapidly changing applications of synchrotron radiation in various disciplines, countries around the world are competing to build synchrotron radiation devices. At present, there are approximately 68 synchrotron radiation devices worldwide, distributed in 23 countries and regions, including 25 third-generation synchrotron radiation light sources that have been built or are under construction.

The first batch of 7 beam line stations and 1 time-sharing branch line station constructed by Shanghai Light Source began trial operation for domestic users on May 6, 2009. The newly built protein facilities, including Line 5 and 6 stations, and the Dream Line, have been officially put into operation since their acceptance in 2015. Currently, a total of 13 beam lines and 16 experimental stations have been opened. By 2020, Shanghai Light Source will have nearly 40 beam line stations open to users.

Beijing High Energy Synchrotron Radiation Light Source
The 13th Five Year Plan for the Construction of National Major Science and Technology Infrastructure
One of the major scientific installations with priority layout
Will be applied in fields such as basic science and engineering science
Providing an important support platform for original and breakthrough innovative research

Planned to be completed and put into operation by 2025
What do scientists first need to solve the "protein mystery" at the micron level? A large scientific installation, an advanced light source that can penetrate microscopic matter. On January 6th, the National Major Science and Technology Infrastructure Beijing High Energy Synchronous Radiation Light Source (HEPS) project located in Huairou Science City completed the construction of the main steel structure, and the device area with a circumference of nearly 1.4 kilometers was officially connected into a ring. The Beijing high-energy synchrotron radiation light source, symbolizing the "light of hope", is like a "window" to the micro world. After completion, it will become the fourth generation synchrotron radiation device with the highest brightness in the world.
