Cosmic-ray muon radiography, also called muography, can exploit the internal structure of an object that muons traversed. In the conventional absorption method, transmission or absorption ratio to background terrestrial muon flux can determine the density length. After the scattering method was invented, muography can inspect nuclear materials' existence in targets. The identification is...
Atmospheric ray tomography (ART) uses the muons and electrons for detecting objects and their composition. In this talk I will describe some new methods and a proof-of-concept tomography system developed for the ART of low-Z materials. Recently we introduced the Particle Track Filtering (PTF) and Multi-Modality Tomographic Reconstruction (MMTR) methods. Having Geant4 models we optimized...
In 1970 L. Alvarez et al. reported on the first experiment to use cosmic-ray muons to investigate the interior of a very large structure. This structure was Khafre's Pyramid at Giza. The group used, for that era, state-of-the-art instrumentation from the field of high-energy physics: spark chambers. In the intervening 40+ years, the technology used for determining the trajectories of...
