Recently, the research findings of Professor Liu Zhiyi's team from the School of Nuclear Science and Technology, Lanzhou University, have been published in the internationally renowned applied physics journal Journal of Applied Physics (Volume 138, Issue 19, 2025). The team proposed a novel industrial level monitoring method using cosmic ray muons and verified its reliability in large storage tanks and complex operating conditions, marking another significant advancement in muon application research at our university.

Entitled Feasibility Study of a Novel Level Meter Using Cosmic Ray Muons, the paper addresses the technical challenge of "inaccurate and unsafe level monitoring" in industrial production. It proposes leveraging the intrinsic, environmentally friendly, continuous, and highly penetrative properties of cosmic ray muons to achieve non-contact monitoring of material height. This method requires no contact with materials or artificial radioactive sources, and can operate stably for a long time under complex conditions such as high dust and high corrosion.

Through simulations and experiments, the team systematically evaluated the detection accuracy and applicable conditions of the method. The results demonstrate that the technology can effectively monitor changes in material level within a relatively short measurement period, and holds broad application potential in fields including industrial storage tank safety management and chemical process control.

Published by the American Institute of Physics (AIP), Journal of Applied Physics is a prominent academic journal with international influence in the field of applied physics. The publication of this achievement reflects the international academic community's recognition of our university's research strength and innovation capability in the field of muon imaging technology and engineering applications.
