Highly penetrating cosmic ray muons constantly shower the earth at a rate of about 1 muon per cm<sup>2</sup> per minute. We have developed a technique which exploits the multiple Coulomb scattering of these particles to perform nondestructive inspection without the use of artificial radiation. In prior work , we have described heuristic methods for(More)
We have built a detector capable of locating high Z objects in the sampling (middle) region of the detector. As atomic number increases, radiation length rapidly decreases, yielding larger variance in scattering angle. Cosmic ray muon tomography works by tracking muons above the sampling region, and tracking them below the region as well. The difference(More)
Scattering muon radiography was proposed recently as a technique of detection and 3-d imaging for dense high-Z objects . High-energy cosmic ray muons are deflected in matter in the process of multiple Coulomb scattering . By measuring the deflection angles we are able to reconstruct the configuration of high-Z material in the object . We discuss the methods(More)
Each minute, about 10000 muons rain down on every square meter of Earth. These charged elementary particles are produced by cosmic rays striking the upper atmosphere. Millions of highly penetrative muons pass through our bodies, cars and houses daily. Penetrating the objects, muons interact with atoms of different materials, mainly electromagnetically. They(More)
