Puy de Dôme Volcano Structure

At Puy-de-Dôme, France, starting in 2010, data collection was carried out with the TUMOVOL muon telescope. The telescope used resistive plate chambers (RPCs) to detect the muons through a gas sensitive to ionization caused by the particles when they pass through the detector.

The Puy-de-Dôme is a dormant volcanic dome with a known geological structure and therefore an excellent case study to test the tomography equipment. In the results, features with previously unknown densities were detected at the top of the dome which were later confirmed with gravimetry.
