ADVANCED APPLICATIONS OF COSMIC-RAY MUON RADIOGRAPHY
… sealed drift tubes, the Mini Muon Tracker (MMT). Geant4 simulations were compared to the data for verification and validation. In both the data and simulation, we can identify regions of interest in the reactor including the core, moderator, and shield. This study reinforces our claims for using …

Studying the background response of Minihalo for design optimizations
… to determine an optimal design for Minihalo, GEANT4 simulations of the proposed design are carried out to study how the detector responds to background at the Facility. Accurate fluxes of cosmic muon and gamma-ray backgrounds at the SNS Facility are simui lated and fired onto the detector. The …

Search for cosmic-ray antiparticles with bolloon-borne and space-borne experiments
… interactions of cosmic rays in the atmosphere. GEANT4 simulations were carried out which determine the atmospheric background and attenuation especially for antiparticles. Projected results taking the effects of the atmosphere and the detector properties into account are discussed. The second …
