“…As previously reported, a sample of cosmic rays can provide the relative position x D and inclination θ D of the two telescopes (see [38] for details). For a given number of muons, we repeated the estimation many times and calculated the standard deviation of the obtained distribution.…”

Cosmic ray radiation, thanks to its high penetration capability and relative abundance, has been successfully used in scientific research and civil applications for a long time. For example, techniques based on the attenuation of cosmic ray muons or on their angular scattering have been used to study the inner structure of volcanoes, to search for hidden chambers in Egyptian pyramids, to inspect nuclear waste containers and to monitor blast furnaces. In addition to these imaging techniques, cosmic ray muons have also been used for the detector alignment in large experiments in nuclear and elementary particle physics. In this context, a cosmic muon detection system for the stability monitoring of historical buildings will be here presented. The employment of cosmic rays is envisaged where the time scale of deformations is typically very long, and where conservation constraints could prevent the use of standard mechanical systems. The stability monitoring of Palazzo della Loggia (Brescia, Italy) has been considered as a case study, and performance and limitations of the technique have been evaluated using Monte Carlo (MC) simulations. A muon detection system based on two telescopes with three sensitive layers of scintillating fibers coupled to silicon photomultipliers has been studied. Results from MC studies, taking into account systematic uncertainties, are here presented. Finally, the main features and performance of a small-size detector prototype, developed as a proof of principle and consisting of three layers of 3x3 mm 2 scintillating fibers, as those used in the simulations, are also described.

“…Distance ranging by measuring the time of flight (TOF) of muons has been applied to the adjustment of detector alignments 39 , 40 . There also have been some attempts to monitor the stability of historical buildings 41 . However, the range has been limited thus far: typically, from a few meters to the 10-m scale.…”

Muometric positioning system (μPS) with cosmic muons as a new underwater and underground positioning technique

Thus far, underwater and underground positioning techniques have been limited to those using classical waves (sound waves, electromagnetic waves or their combination). However, the positioning accuracy is strongly affected by the conditions of media they propagate (temperature, salinity, density, elastic constants, opacity, etc.). In this work, we developed a precise and entirely new three-dimensional positioning technique with cosmic muons. This muonic technique is totally unaffected by the media condition and can be universally implemented anywhere on the globe without a signal transmitter. Results of our laboratory-based experiments and simulations showed that, for example, plate-tectonics-driven seafloor motion and magma-driven seamount deformation can be detected with the μPS.

“…Their flux, energy spectrum, angular distribution and interaction with matter (energy loss, multiple scattering, etc. ), are reasonably well known 8 , allowing the use of secondary muons as a probe to investigate many aspects of the world around us 9 , from the search of hidden chambers in the Egyptian pyramids 10,11 to imaging the content of cargo containers [12][13][14][15][16] , or even the monitoring of large civil structures 17,18 . X-rays or neutrons are used for medium size objects, but for larger objects the attenuation of such probes would be too high.…”

At Mount Etna volcano, the focus point of persistent tectonic extension is represented by the Summit Craters. A muographic telescope has been installed at the base of the NorthEast Crater from August 2017 to October 2019, with the specific aim to find time related variations in the density of volcanic edifice. The results are significant, since the elaborated images show the opening and evolution of different tectonic elements; in 2017, a cavity was detected months before the collapse of the crater floor and in 2018 a set of underground fractures was identified, at the tip of which, in June 2019, a new eruptive vent started its explosive activity, still going on (February, 2020). Although this is the pilot experiment of the project, the results confirm that muography could be a turning point in the comprehension of the plumbing system of the volcano and a fundamental step forward to do midterm (weeks/months) predictions of eruptions. We are confident that an increment in the number of telescopes could lead to the realization of a monitoring system, which would keep under control the evolution of the internal dynamic of the uppermost section of the feeding system of an active volcano such as Mount etna.
