Atmospheric muons are an essential component of cosmic ray showers. Conducting research of cosmic muons imaging can promote the development and application of muon science and muon beam imaging technology. As the frontiers of basic science, it shows vital scientific significance. The program aims at the development and application of muon imaging technology, which includes systematically studying the physical process of muon through matter and understanding its interaction mechanism, studying the muon multi-information imaging methods by obtaining its time/ position/ momentum during transmission, optimizing image reconstruction algorithms to improve muon imaging performance and identification capability, as well as to reduce imaging time consuming, and building a imaging system with the multi-information acquisition to explore the application of muon imaging in nuclear systems. The program will greatly contribute to the application of muon imaging in the nuclear security monitoring and major engineering of national defense, which shows broad applications prospects in nuclear security monitoring of the defense and nuclear energy.
