Muon tomography is a technique that uses cosmic ray muons to generate three dimensional images of volumes using information contained in the Coulomb scattering of the muons. Advantages of this technique are the ability of cosmic rays to penetrate significant overburden and the absence of any additional dose delivered to subjects under study above the natural cosmic ray flux. Disadvantages include the relatively long exposure times and poor position resolution and complex algorithms needed for… 
Analysis of the multigroup model for muon tomography based threat detection
We compare different algorithms for detecting a 5 cm tungsten cube using cosmic ray muon technology. In each case, a simple tomographic technique was used for position reconstruction, but the
Imaging the inside of thick structures using cosmic rays
The authors present here a new method to image reinforcement elements inside thick structures and the results of a demonstration measurement performed on a mock-up wall built at Los Alamos National
A modified multi-group model of angular and momentum distribution of cosmic ray muons for thickness measurement and material discrimination of slabs
Muon tomography is a capable imaging technique to measure the geometry of high-Z objects. However, most existed algorithms used in muon tomography have obscured the effects of angular distribution
Slit identification for a uranium slab using a binary classifier based on cosmic-ray muon scattering
Traditional muon tomographic method has been fraught with difficulty when it is applied to identify some defective high-Z objects or other complicated structures, since it usually gets into trouble
Penetrating radiation: applications at Los Alamos National Laboratory
Los Alamos has used penetrating radiography extensively throughout its history dating back to the Manhattan Project where imaging dense, imploding objects was the subject of intense interest. This
Application of muon tomography to fuel cask monitoring
TLDR
It is shown that muon tomography can provide a fingerprint of a loaded fuel cask, because of its sensitivity to both the density and atomic charge of the spent fuel, and that it is sensitive to many diversion scenarios.
Detecting metal elements inside the dome of Santa Maria del Fiore in Florence using cosmic ray muons
As part of the ongoing study of Brunelleschi’s great dome in Florence, the Opera di Santa Maria del Fiore has approved a proposal to solve the age-old problem of the possible presence of hoops or
Imaging the dome of Santa Maria del Fiore using cosmic rays
TLDR
Multiple scattering muon radiography is a non-destructive imaging method that can be used to image the interior of the dome's wall and therefore ascertain the layout and status of any iron substructure in it.

Statistical Reconstruction for Cosmic Ray Muon Tomography
TLDR
A maximum likelihood/expectation maximization maximization tomographic reconstruction algorithm designed for the technique which exploits the multiple Coulomb scattering of muon particles to perform nondestructive inspection without the use of artificial radiation.
Tomographic Imaging with Cosmic Ray Muons
Over 120 million vehicles enter the United States each year. Many are capable of transporting hidden nuclear weapons or nuclear material. Currently deployed X-ray radiography systems are limited
Surveillance: Radiographic imaging with cosmic-ray muons
TLDR
It is shown that natural background muons, which are generated by cosmic rays and are highly penetrating, can be used for radiographic imaging of medium-to-large, dense objects, without these limitations and with a reasonably short exposure time.
Obtaining material identification with cosmic ray radiography
The passage of muons through matter is dominated by the Coulomb interaction with electrons and nuclei in the matter. The muon interaction with the electrons leads to continuous energy loss and
