| Description: |
This interdisciplinary project focuses on the development of “muography”, an imaging technique that relies on the measurement of the absorption and/or the deviation of muons that are freely and abundantly produced by the interactions of cosmic rays with the atmosphere, by applying detection, simulation and data analysis methods developed in the context of High Energy Physics (HEP) experiments. The thesis concerns two major aspects in the field of muography and as such, it is divided into the following two parts. The first part involves the development and instrumentation of a portable, robust and gas-tight detector based on glass Resistive Plate Chambers (RPCs) for multipurpose muography applications. The fabrication of the detector was performed in-house at CP3, UCLouvain, with an aim to operate under challenging operational and logistical conditions for various applications that include but are not limited to geophysical prospections, archaeological/cultural studies, nuclear reactor monitoring, nuclear waste characterization, underground mapping, etc. Preliminary results from the performance studies of the current prototype are shown and discussed, in addition to the results from a novel multiplexing toy simulation. The experiment involving muographic study of Mt. Vesuvius, namely MUon RAdiography of VESuvius (MURAVES) experiment, is the focus of the second part of this thesis. From the preliminary analysis of the data collected up to 2022 using two identical MURAVES detectors (NERO and ROSSO), the right-left asymmetry in density was observed, which seems to be consistent with the eruption history of Mt. Vesuvius from the geophysical point of view. In order to confirm this initial observation, a subsequent independent analysis aiming also to take into account the data collected by the third MURAVES detector (BLU) was carried out and the results are presented and discussed. In addition, the first attempts at the time of flight measurements with MURAVES data are also shown in this thesis. ; (SC - Sciences) -- ... |
