In March this year, the second phase of the China Spallation Neutron Source (CSNS phase II), a major national scientific and technological infrastructure in China, kicked off its construction in Dongguan, Guangdong Province. The project mainly involves the construction of 11 neutron spectrometers and experimental terminals. Upon completion, the number of neutron spectrometers will increase to 20, with the addition of the first domestic muon experimental terminal and high-energy proton experimental terminal. The construction period is expected to take 5 years and 9 months.
The spallation neutron source dubbed the "super microscope" probes the microstructure of materials through neutrons. Over the past five years, research results from the CSNS have directly addressed major national strategic needs while also supporting the development of high-end manufacturing in the Guangdong-Hong Kong-Macao Greater Bay Area. This includes studies on metal fatigue in key aviation components, the safety and lifespan of in-service high-speed rail wheels, battery performance in electric vehicles, and spin fluctuations of high-temperature superconducting materials.
Upon completion of phase II, the research capabilities of the CSNS will be greatly enhanced, basically covering all application areas of neutron scattering. This will bring a significant improvement in experimental accuracy and efficiency, providing stronger support for exploring scientific frontiers, addressing major national needs, and solving key issues in industrial development.
