Novel muon imaging techniques

Area of Science:

• Physics
• Geophysics
• Nuclear Engineering

Background:

• Muon imaging leverages the high penetrating power of cosmic ray muons for non-invasive inspection.
• Similar to medical CT scanners, muon imaging reveals internal structures of dense or shielded objects.

Purpose of the Study:

• To review the principles of muon imaging techniques.
• To discuss image reconstruction algorithms for muon imaging.
• To demonstrate muon imaging capabilities for spent fuel casks.

Main Methods:

• Muon absorption imaging: based on muon flux attenuation.
• Muon multiple scattering imaging: based on muon scattering in matter.
• Geant4 simulation study for imaging nuclear spent fuel casks.

Main Results:

• Muon absorption imaging is suitable for large-scale objects (volcanoes, buildings) and smaller ones (spent fuel casks).
• Muon multiple scattering imaging is optimal for smaller objects like nuclear waste containers.
• Simulations validated the potential of muon imaging for spent fuel cask inspection.

Conclusions:

• Muon imaging techniques are versatile, applicable to diverse fields from volcanology to nuclear safeguards.
• The principles and algorithms of muon imaging are crucial for advancing non-destructive testing.
• Further research and simulation studies, like the one presented, enhance the practical application of muon imaging.
