Résumé(disponible en anglais seulement)
Cosmic ray muons are a natural, abundant, highly-penetrating particle flux that continuously showers the earth's surface and penetrates hundreds of meters underground. Muons are attenuated as they pass through matter so that the flux below ground is dependent on the total integrated mass traversed by the particles. Recently, sensors have been placed in existing tunnels to observe the muon flux for brown-field mining applications. We have developed an algorithm to invert muon tomography data, along with gravity data, to recover a 3D distribution of density contrast. The difference in physics between muon ray-paths and gravity data provides a unique insight into the subsurface.
