Located in Songshan Lake, Dongguan, the China Spallation Neutron Source (CSNS) is the first national major scientific infrastructure in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) and the world's fourth pulse spallation neutron source. As of now, the CSNS has registered 7,117 users, with a quarter of them from the GBA. The facility has completed over 1,700 user experiments, achieving significant scientific results in key fields such as aviation, aerospace, high-speed rail, ships, new energy, and materials science.

The CSNS functions like a "super microscope," using the penetrating ability of neutrons to study the microscopic structures and movements of materials. In the field of new energy vehicles, it was the first to discover an uneven phenomenon of lithium-carbon compounds during battery charge and discharge processes, laying the foundation for improvements in lithium battery performance. Its Energy-Resolved Neutron Imaging Spectrometer (ERNI) has advantages such as deep penetration and sensitivity to light elements, enabling precise measurements of battery reaction mechanisms and uneven reaction levels, which assist in battery design optimization and performance enhancement.

In the future, ERNI will play a significant role in areas such as new energy, new materials, and high-end equipment manufacturing, while also being applied to specialized research fields like cultural heritage, archaeology, plant physiology, geology, and deep-sea studies.

Currently, the CSNS has established partnerships with many domestic battery companies and has achieved significant results in aviation, aerospace, high-speed rail, ships, and new energy sectors. For example, it has provided a research platform for aircraft airworthiness certification in the aviation and aerospace industry and offered data support for improving the safety and performance of high-speed rail.
