Functional Description
Cosmic ray muons, with their strong penetration capability and naturally non-radiative characteristics, exhibit unique advantages in imaging heavy nuclear materials and large-scale objects, forming a distinct technical complementarity to relatively mature imaging technologies such as X-rays and neutrons. Leveraging their inherent availability, cosmic ray muon imaging eliminates the need for traditional radiation generators used in conventional ray imaging technologies, produces no additional ionizing radiation, and offers safety, reliability, and operational convenience, making it an emerging next-generation non-destructive imaging technology.
The cosmic ray muon imaging technology based on large-area Micromegas detectors demonstrates immense application potential due to its advantages of high spatial resolution, large-area coverage, cost controllability, and batch production capability. Through years of technological accumulation, our company has achieved batch production of large-area, high-performance Micromegas detectors, with mature manufacturing processes, providing robust hardware support for the widespread application of cosmic ray muon imaging systems.
Through system integration, we have realized an integrated design of detectors, electronics systems, and mechanical structures, forming a high-resolution muon transmission imaging system—the "Muon Cart." This system enables long-distance field deployment for outdoor testing while achieving full-range directional steering across a 2π solid angle.
This system can be applied to muon imaging research and exploration in diverse fields, including:
1. Natural disaster monitoring: Imaging volcanic activity, earthquake fault zones, and large-scale hydraulic facilities.
2. Geological and mineral exploration: Detecting and imaging geological structures, metallic minerals, natural gas deposits, etc.
3. Cultural heritage: Applications in tomb imaging, historical site analysis, and large-scale cave system mapping.
