“…Early uses included probing Chephren's pyramid (Alvarez et al, 1970) and estimating the rock overburden on mountains (George, 1955). The counting of the number of atmospheric muons surviving through the structure provides a radiographic measurement of the matter distribution along the line of flight of the muons (Nagamine, 2004). If the topography is further known, by repeating the measurement from different locations, tomographic threedimensional models of the matter's density distribution can then be computed (Tanaka et al, 2010).…”

Abstract. High-energy (above a few hundred GeV) atmospheric muons are a natural probe for geophysical studies. They can travel through kilometres of rock allowing for a radiography of the density distribution within large structures, like mountains or volcanoes. A collaboration between volcanologists, astroparticle and particle physicists, TOMUVOL was formed in 2009 to study tomographic muon imaging of volcanoes with high-resolution, large-scale tracking detectors. We report on two campaigns of measurements at the flank of the Puy de Dôme using glass resistive plate chambers (GRPCs) developed for particle physics, within the CALICE collaboration.

Cosmic-ray muons (CRM) arriving from the sky on the surface of the earth are now known to be used as radiography purposes to explore the inner-structure of large-scale objects and landforms, ranging in thickness from meter to kilometers scale, such as volcanic mountains, blast furnaces, nuclear reactors etc. At the same time, by using muons produced by compact accelerators (CAM), advanced radiography can be realized for objects with a thickness in the sub-millimeter to meter range, with additional exploration capability such as element identification and bio-chemical analysis. In the present report, principles, methods and specific research examples of CRM transmission radiography are summarized after which, principles, methods and perspective views of the future CAM radiography are described.

“…Recent detector developments resulted in the availability of large area trackers with very fine segmentation, making possible to take one step further the muon imaging by applying it to km scale targets, as the volcanoes [2]. The basic idea behind muon imaging of volcanoes is that measuring the absorption of the muon flux as function of the direction at a fixed location permits mapping out the average column density in the volcano once the topography is known.…”

on behalf of the TOMUVOL CollaborationTheir 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 volcanoes with high-resolution tracking detectors. By exploiting Glass Resistive Plate Chambers (GRPCs) with a semidigital readout developped for ILC hadronic calorimetry within the CALICE collaboration, TOMUVOL aims to improve the understanding of volcanic processes and may finally contribute to reducing volcanic hazards. In 2011, TOMUVOL operated a muon telescope with three parallel detection planes at the flank of the Puy de Dôme, an inactive volcanic dome situated in the Massif Central (southcentral France). This contribution presents preparatory work towards muon tomography as well as flux measurements obtained after the first months of data taking.
