The Thermal Plumbing System of Stromboli Volcano, Aeolian Islands (Italy) Inferred From Electrical Conductivity and Induced Polarization Tomography

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 6, June 2023., 2023
Abstract We performed the first 3D island‐scale tomography of the electrical conductivity of Stromboli volcano (Aeolian Islands, Italy) using 2D acquisition lines (37.2 km) and a total of 18,880 measurements and 2,402 unique electrode locations. This 3D data set was inverted using a Gauss‐Newton algorithm, parallel‐processing on an unstructured ...

The use of muon radiography in safeguarding geological repositories [PDF]

Safety of Nuclear Waste Disposal, 2021
Abstract. Muon radiography is a technique that harnesses naturally occurring cosmic radiation to noninvasively determine the density of an object of interest. The technique has many similarities to that of medical X-ray examinations and can supply detailed density maps of the object. We propose the application of muon radiography to aspects of the long-

Muon Imaging of Volcanic Conduit Explains Link Between Eruption Frequency and Ground Deformation

Geophysical Research Letters, Volume 50, Issue 2, 28 January 2023., 2023
Abstract Understanding the physical mechanism of ground deformation at a volcano supports the use of deformation data as a monitoring tool. An inverse correlation was observed between eruption frequency and ground deformation of Sakurajima volcano from November 2018 to April 2021.

Application of Muon Radiography to Blast Furnaces: the BLEMAB project [PDF]

, 2022
Muon radiography is a non-invasive imaging technique that exploits cosmic ray muons to explore the content of large, dense and otherwise inaccessible volumes.

Interpreting muon radiographic data in a fault zone: possible application to geothermal reservoir detection and monitoring [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2013
Rainfall-triggered fluid flow in a mechanical fracture zone associated with a seismic fault has been estimated (Tanaka et al., 2011) using muon radiography by measuring the water position over time in response to rainfall events. In this report, the data

Potential of combined neutron and X‐ray imaging to quantify local carbon contents in soil

European Journal of Soil Science, Volume 73, Issue 1, January–February 2022., 2022
Abstract In this study, we investigated the potential and limitations of using joint X‐ray and time‐of‐flight (TOF) neutron imaging for mapping the 3‐dimensional organic carbon distribution in soil. This approach is viable because neutron and X‐ray beams have complementary attenuation properties.

Development and operation of a muon detection system under extremely high humidity environment for monitoring underground water table [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2013
In order to investigate the complex nature of landslides triggered by rainfall, dynamic muon radiography of the motion of the underground water table is planned in a drainage tunnel drilled underneath an estimated fault plane.

Laser-driven muon production for material inspection and imaging

Frontiers in Physics, 2023
We numerically show that laser-wakefield accelerated electron beams obtained using a PetaWatt-scale laser system can produce high-flux sources of relativistic muons that are suitable for radiographic applications.
