Journal ArticleDOI
Surveillance: Radiographic imaging with cosmic-ray muons.
Konstantin N. Borozdin,Gary E. Hogan,Christopher Morris,William C. Priedhorsky,Alexander Saunders,Larry J. Schultz,Margaret E. Teasdale +6 more
TL;DR: 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.
Journal ArticleDOI
Image Reconstruction and Material Z Discrimination via Cosmic Ray Muon Radiography.
Larry J. Schultz,Larry J. Schultz,Konstantin N. Borozdin,J.J. Gomez,Gary E. Hogan,J.A. McGill,Christopher Morris,William C. Priedhorsky,Alexander Saunders,Margaret E. Teasdale,Margaret E. Teasdale +10 more
TL;DR: In this article, the concept and theory behind cosmic ray muon radiography was described, and the information carried by the scattered muons and their approaches for exploiting that information with image reconstruction algorithms were discussed.
Journal ArticleDOI

TL;DR: In this paper, an optimized search for oscillations using free neutrons from a slow neutron moderator could improve existing limits on the free oscillation probability by at least three orders of magnitude.
Journal ArticleDOI

Zeck,B. A. Zeck +40 more
TL;DR: The lifetime of the neutron lifetime was measured in a trap where ultracold polarized neutrons were levitated by magnetic fields, precluding interactions with the trap walls, to aid the understanding of how the first nuclei formed after the Big Bang.
Journal ArticleDOI
Detection of high-Z objects using multiple scattering of cosmic ray muons
William C. Priedhorsky,Konstantin N. Borozdin,Gary E. Hogan,Christopher Morris,Alexander Saunders,Larry J. Schultz,Margaret E. Teasdale +6 more
TL;DR: Borozdin et al. as mentioned in this paper demonstrated that high-Z material can be detected and located in three dimensions using radiographs formed by cosmic-ray muons, which is an important and timely task given the danger associated with illegal transport of uranium and heavier elements.
