Jacques Marteau

Researcher

Jacques Marteau is the head of the muography group and deputy director of IP2I. He has worked in particle physics for 20 years, participated in long baseline neutrino oscillations experiments, such as OPERA (DAQ project leader), T2K and DUNE. He has developed an expertise in distributed smart acquisition systems and, in 2008, launched the first experimental muography program in France, in collaboration with geophysicists, with active volcanoes as primary targets (Soufrière in Guadeloupe, Etna, Mayon) and then extended the applications to geotechnics (mining, civil engineering, non-invasive control and monitoring). He was awarded with the Prix Thibaud in 2012 for his pioneering works in muography.

Marina Rosas Carbajal

Researcher

Marina is a CNRS Researcher on Volcanology, working at the Institute of Earth Physics of Paris (IPGP, Université de Paris). She received her PhD in Earth and Environmental Sciences from the University of Lausanne (Switzerland), after graduating as a Geophysicist from the National University of La Plata (Argentina). She then obtained 3 consecutive postdoctoral fellowships from the Swiss National Science Foundation, and from the AXA Research Fund, to study the volcano La Soufrière de Guadeloupe. Her research focuses on how volcano hydrothermal systems develop, and how they influence heat and fluid transport in the volcano. She uses muon tomography to scan the interior of volcanoes and how they evolve over time, and numerical modeling to understand volcano dynamics and potential hazards.

Antoine Chevalier

Postdoctoral Researcher

Born with an unquenchable thirst for Earth science, Antoine originally comes from the geophysics field of practice. His goal: understanding the inside of complex structures (geological or man-made) from indirect measurements. As such, he has a knack for 3D imagery reconstruction algorithms and data analysis applied to any physical measurements he can get his hands on. With muon detectors feeding him with a daily and massive amount of data, he is now over the muon!

Amelie Cohu

Phd Researcher

Amélie is a PhD student at IP2I. She obtained a master's degree in climate physics in Lyon and is very interested in the interdisciplinarity between atmospheric issues and particle physics. Her research focuses on atmospheric phenomena and their impacts on the flux of cosmic rays detected on the Earth's surface. Part of this job relies on CORSIKA simulation, tuned on experimental data recorded with tracking detectors. Since the second cosmic ray spectrum is the component of cosmic rays used in muon tomography, this detailed study has direct implication for both muon absorption tomography and muon scattering tomography. Accurate knowledge of the cosmic ray flux makes it possible to evaluate the optimal measurement configuration too. The modelisation of the muon flux at a specific location is a key ingredient of the method in any application, from volcanology to imaging and monitoring of industrial large structures.

Matias Tramontini

Phd Researcher

Matías is a geophysicist that is currently doing a PhD at the National University of La Plata (Argentina). His field of work is muography applied to geological bodies. His research focuses on the use of this technique to study how mass is distributed inside volcanoes and to monitor volcanic hydrothermal activity. The goal of his research is to gain insight into how volcanoes evolve over time and to help assess potential hazards associated with them.

Theodore Avgitas

Researcher

My first acquaintance with muon tomography was in the year 2018, when I took up a post-doc position at the Astroparticle and Cosmology Laboratory (APC) in Paris on the Arche project. I was involved with the detector installation at the Apollonia Tumulus site, the data acquisition monitoring and the preliminary data-quality evaluation and analysis. Before that I was a PhD researcher at APC where my work revolved around the characterisation and performance evaluation of optical modules used for the KM3NeT and ANTARES neutrino telescopes. I currently work as a post-doc researcher at the Institute de Physique des 2 Infinis (IP2I) de Lyon for the REINFORCE program, mainly focusing on broadcasting the experimental aspects of muon tomography to citizen scientists by capitalising on the numerous studies that the DIAPHANE team has performed during the last decade.
