2026-07-05

On 3 July, at the ‘Forum on Fostering and Developing Future Industrial Scenarios through Green Nuclear Technology’, jointly organised by Lanzhou University, the Gansu Economic Research Institute, the Gansu Nuclear Industry Research Institute and other organisations, a pre-launch ceremony was held for *Natural Muon Technology and Its Applications* (Volumes I and II).

Workshop on Muon Imaging-Based Hazard Detection Technology for Earth-Rock Dams Held in Nanjing

2026-03-07

A symposium on muon imaging technology for detecting potential hazards in rock-fill dams was held in Nanjing. Over ten experts from institutions including the Nanjing Hydraulic Research Institute, Lanzhou University, and Henan Zhongyuan Optoelectronics attended the event, engaging in in-depth discussions on the preliminary findings from China's first field trial of muon imaging technology applied to rock-fill dams.

Performing a 3D “CT Scan” on the Dam Lanzhou University Team Collaborates with Henan Zhongyuan Optoelectronics and Others to Complete Muon Imaging Test on Mangshan Reservoir Auxiliary Dam

2026-03-03

The Lanzhou University team, in collaboration with Henan Zhongyuan Optoelectronics and other institutions, has completed imaging tests from Yangshan Reservoir to Dui Jianzi. This field trial employed natural mountain radiation to conduct a three-dimensional “T-road view” of the existing structure and adjacent slopes, achieving density imaging of complex rock masses. This breakthrough provides a novel non-destructive technical pathway for human-scale safety monitoring.

Professor Liu Zhiyi's research team has been invited by the internationally renowned geoscience journal Geographical Journal to publish a review article entitled Research Progress of Muography in China.

Recently, Professor Liu Zhiyi's research team at our university was invited by the internationally renowned geoscience journal Journal of Geography, Chigaku Zasshi to publish a cover review article entitled ‘Research Progress of Muography in China’ in Volume 134, Issue 6, 2025. This paper systematically reviews the development history and current research status of muon imaging technology in China, introducing the technical principles of both transmission and scattering imaging. Through exemplary case studies—including simulated research at the Qin Shi Huang Mausoleum by Beijing Normal University, volcanic detection by the Beijing Institute of Satellite Environmental Engineering, and Xi'an City Wall conservation by Lanzhou University—the paper demonstrates muography's potential applications in cultural heritage preservation, mineral resource exploration, and infrastructure monitoring. Notably, Lanzhou University's independently developed CORMIS triangular plastic scintillator imaging system achieved multiple domestic firsts in field deployment.

Starting today, this newspaper will launch a series of reports highlighting the research strengths and technological innovation achievements of Lanzhou's universities.

Muon Imaging: How Cosmic Rays Help Us Analyze Ancient Walls, Pyramids, and Volcanoes

2025-03-12

Our universe is filled with countless cosmic rays, streaking through space at near-light speeds. These rays can be emitted by the Sun or formed by supernova explosions in distant galaxies. They consist of trillions of subatomic particles. Every second, Earth is bombarded by cosmic rays. When cosmic rays collide with Earth's atmosphere, some are deflected by the planet's magnetic field, while others reach us without causing harm. As cosmic rays traverse the atmosphere, they undergo a series of reactions that generate vast quantities of new subatomic particles. Among these are muons.

Leading Italian universities engage in collaborative exchanges with cutting-edge science centers

2025-03-03

On the afternoon of February 25, at the invitation of the Frontier Science Center for Rare Isotopes at Lanzhou University and the National Institute for Nuclear Industry, Professor Giulio Saracino from the University of Federico II in Naples, Italy, and researcher at the National Institute for Nuclear Physics (INFN), conducted an academic exchange at the Science and Engineering Building of Lanzhou University. He delivered a special report titled "Cosmic Ray Muon Imaging Techniques and Their Applications."Faculty and students from the Center for Frontier Science of Rare Isotopes and the National Institute of Nuclear Industry actively participated in the event. The lecture was chaired by Professor Liu Zhiyi, Vice President of the National Institute of Nuclear Industry and Principal Investigator of the Center for Frontier Science of Rare Isotopes.
