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.

Professor Saracino's presentation centered on the principles of muography technology and its diverse applications. He began by outlining the fundamental properties of muons and their production mechanisms in the atmosphere, followed by a detailed explanation of how muon beams penetrate matter to probe the internal structures of large-scale objects. He presented successful case studies of muography in archaeological exploration, volcanic monitoring, and underground space detection, including an example of imaging subterranean caves using planar and cylindrical detectors in Naples, Italy. Additionally, he introduced a recent study employing muon radiation to probe the internal structure of salt mines, assessing their feasibility as hydrogen storage facilities while exploring their geological characteristics.

During the Q&A session following the presentation, faculty and students actively engaged in discussions, delving into technical details of muon ray detection, data processing methods, and future application directions. Professor Giulio Saracino highly commended Lanzhou University's research achievements in muon detection and imaging technology, expressing anticipation for further collaborative opportunities in the future.

In addition to his academic presentation, Professor Giulio Saracino engaged in in-depth discussions with Vice Dean Shi Keliang and Professor Li Peirong, Head of the High Energy Physics Group, regarding inter-institutional and inter-departmental collaboration. Both parties exchanged views on potential future cooperation in nuclear technology, high-energy physics, and related fields, while also exploring possibilities for jointly applying for international research projects and establishing talent development partnerships.

During his visit, accompanied by Professor Liu Zhiyi, Professor Giulio Saracino also inspected the muon detection equipment at the Maijishan Grottoes. This non-invasive technology, utilizing muon ray imaging, is employed to examine the internal structures of the grottoes, thereby contributing to the preservation and research of this World Cultural Heritage site. Professor Giulio Saracino expressed high recognition for the project's research methodology and achievements, commending China's innovative practices in applying modern physics technologies to cultural heritage preservation.

This academic exchange and collaborative discussion further deepened cooperation between Lanzhou University and internationally renowned research institutions in the field of nuclear science and technology, laying a solid foundation for future joint research and talent development.
