On May 17, the China Spallation Neutron Source (CSNS) opened its doors to the public for its 8th Public Science Day, themed "Unlocking the Future Through Scientific Inquiry." The event offered a diverse lineup of popular science lectures, hands-on experiments, and guided tours of the national mega-science facility, delivering an engaging celebration of cutting-edge technology. A livestream on Southern+ also allowed online audiences to "virtually explore" the CSNS facility.
In his opening speech, Tong Xin, Deputy Director of the Dongguan Branch of the Institute of High Energy Physics (IHEP), emphasized that the value of science lies not only in breakthroughs but also in spreading scientific spirit and knowledge. "Science communication and public outreach have always been a core mission of mega-science facilities," he noted. Since its inception, CSNS has prioritized science popularization, organizing flagship initiatives like "Science Outreach in Schools" and "Public Science Day" to bridge the gap between research and the public. This event, he added, was a golden opportunity for society to explore scientific wonders together.
Frontier Science Unveiled
During the popular science talks, researchers shared insights on neutron science, nuclear fusion energy, cultural relic preservation, and marine exploration, captivating audiences with the latest advancements. Many families attended to "meet the stars of science"—interacting directly with scientists and making complex topics accessible.
Super "X-ray Vision" for Materials & Artifacts
At the Energy-Resolved Neutron Imaging Spectrometer exhibit, scientists likened the device to "a super camera with X-ray vision," revealing internal structures of objects. Demonstrations showcased its real-world applications—from aerospace material inspection and battery safety research to artifact analysis. Case studies, such as the preservation of a Western Han Dynasty scribe’s knife and Buddhist statues from the Guangdong Museum, illustrated how big science serves society.
Hands-On Science Magic
The interactive zone buzzed with excitement. At the low-temperature superconductivity station, a superconductor cooled with liquid nitrogen levitated and spun smoothly along a magnetic track, creating a "real-life anti-gravity" spectacle that drew gasps. Nearby, children held their breath as they pulled taut a balloon membrane—"Boom!"—releasing an air shockwave that toppled a pyramid of cups.
Art Meets Science
A special "Exploring the Light of Science · Painting Future Dreams" exhibition featured imaginative artworks by students from Songshan Lake Central Primary School and Beiqu School, blending childhood creativity with scientific wonder.
The event drew thousands of on-site visitors, with exhibits, facility tours, and the science-history exhibition hall earning widespread praise. By merging education, entertainment, and innovation, CSNS once again proved how mega-science facilities can inspire the next generation.
