“…The GScan Muon Tracker is based on scintillating fibers, as they are widely used and offer several advantages, making them suitable for a wide variety of applications. The GScan Muon Tracker is a 4-layered prototype hodoscope (3-1 configuration) with 1 mm Saint-Gobain BCF-12 single cladding scintillation fibers [6]. The fibers are arranged as two double-layered fiber mats oriented orthogonally to each other, as shown in Figure 1.…”

The search for water on the Lunar and Martian surfaces is a fundamental aspect of space exploration, contributing to the understanding of the history and evolution of these celestial bodies. However, the current understanding of the distribution, concentration, origin, and migration of water on these surfaces is limited. Moreover, there is a need for more detailed data on these aspects of Lunar and Martian water. The natural flux of cosmic-ray muons, capable of penetrating the planetary surface, offers a method to study the water-ice content, composition, and density of these surfaces. In this paper, the author presents a novel approach to address these knowledge gaps by employing cosmic-ray muon detectors and backscattered radiation. The study describes a cutting-edge muon tracking system developed by GScan and highlights the results of preliminary simulations conducted using GEANT4. These findings suggest that muon tomography could be a potential tool for investigating water-ice content on the Lunar and Martian surfaces, pointing to new avenues for space science exploration.

Cosmic-Ray Tomography for Border Security

A key task for customs workers is the interception of hazardous, illegal and counterfeit items in order to protect the health and safety of citizens. However, it is estimated that only a small fraction of cargo is inspected and an even smaller fraction of trafficked goods are detected. Today, the most widely used technology for scanning vehicles, ranging from vans and trucks to railcars, is γ ray and X-ray radiography. New technologies are required to overcome current technological shortcomings, such as the inability to detect the target material composition, the usage of harmful ionising radiation sources and the resultant low throughput. Cosmic ray tomography (CRT) is a promising technology for cargo screening. Cosmic ray muons have average energies of around 10,000 times larger than a typical X-ray and therefore can penetrate relatively large and dense materials. By analysing muon scattering, it is possible to identify materials hidden inside shielding that is too thick or deep for other imaging methods. CRT is also completely passive, exploiting naturally occurring secondary cosmic radiation, and is therefore safe for humans and animals. Contrary to conventional X-ray- or γ-ray-based imaging techniques, CRT also allows material differentiation and anomaly localisation within the cargo or vehicle through the provision of 3D images. This article reviews the current state-of-the-art technology in CRT, critically assessing the strengths and weaknesses of the method, and suggesting further directions for development.

“…This resolution corresponds to detector design based on multiple layers of scintillating plastic fiber arrays used as position sensitive detectors. The prototype based on such a design was constructed [20] and spatial resolution of 0.15 mm was obtained with a double layer array of round cross-sections plastic scintillating fibers of 1 mm in diameter.…”

An application of muon scattering tomography is investigated for the non-destructive verification of spent nuclear fuel dry storage casks in context of international treaty declarations in proving that the diversion of plutonium has not occurred during long term storage in the spent fuel storage facility. It was shown in the previous studies that the method of muon scattering tomography can provide a detailed 3-D image of the spent fuel container but with the measurement time required for that is in the range of a day or even longer. In this paper, we investigate the feasibility of a fast verification of dry storage casks in order to obtain an immediate answer without a detailed 3-D image reconstruction of container content if at least one fuel assembly is missing. We have performed preliminary modelings using Geant4 of safeguards verification of spent fuel dry storage cask HI-STORM 190 with cosmic ray muons. The simulated data were analysed using the Point of Closest Approach method and Kolmogorov-Smirnov statistical tests. To infer the state of content of dry casks we have performed the comparison and further classification of muon observables for the scenarios of one missing fuel assembly with respect to fully loaded casks. The results of this study indicate that one missing fuel assembly can be detected with measurement times of about 1h.
