Density imaging of volcanos with atmospheric muons

Abstract : Their capability to penetrate large depths of material renders high-energy atmospheric muons a unique probe for geophysical explorations. Provided the topography of the target is known, the measurement of the attenuation of the muon flux permits the cartography of matter density distributions revealing spatial and possibly also temporal variations in extended geological structures. A Collaboration between volcanologists, astroparticle- and particle physicists, TOMUVOL, was formed in 2009 to study tomographic muon imaging of volcanos with high-resolution tracking detectors. This contribution presents preparatory work towards muon tomography as well as flux measurements obtained after the first months of data taking at the Puy de Dˆome, an inactive lava dome volcano in the Massif Central in south-central France.
