“…To detect the tertiary photons, two different photon detectors were applied: a HPGe detector for the investigation of small-size (< 10 cm) samples and a scintillator-based detector for the imaging of organic materials with relatively larger size (< 0.5 m) [OL17,OL18].…”

“…The investigated materials, e. g. a copper sample (Cu cylinder), were placed between the HPGe and the lead absorber wall. The scheme of the imaging system using a HPGe-based photon detector for imaging of low-Z samples is shown in Fig 82 [OL17]. In case of the scintillators, the body of interests, e. g. bones, were placed into the "scintillator box".…”

Muography is a well estabilished method to obtain 3D images of large objects (e.g. volcanoes and large buildings) without any additional particle source, taking advantage of the presence of cosmic muons. The underlying principle of muography is the measurement of individual muon tracks and the determination of their absorption or scattering. These processes depend on the material that they have travelled through. The novel method discussed is based on the measurement of the muon tracks and of the corresponding particles those were produced by the muons themselves in the investigated target.As muons pass through matter they interact with matter by ionization, bremsstrahlung, pair production and nuclear interactions. Our experimental setup is designed in a way to measure both the primary muons and the created secondaries (mostly electrons and gammas). The tracks of the muons are determined by a special kind of Multi-Wire Proportional Chambers (MWPC) called CCC (Close Cathode Chamber). The secondary particles produced in the target are measured by four plastic scintillators placed around the target. The CCC chambers and the scintillators are used in coincidence in order to gather data about muons those passed through the target. As cross sections of the described processes vary by the density and the atomic number of materials this technique could be used to investigate the material content of the target.

“…We have found only a few examples of low-Z ART in non-security applications. Bikit et al demonstrated that low-Z materials can be imaged by the simultaneous detection of cosmic muons and photons created via bremsstrahlung inside the investigated bone and soft tissue sample [18,19]. Another example is inspection of nuclear waste encapsulated in concrete matrix.…”

Cosmic rays interacting with the atmosphere result in a flux of secondary particles including muons and electrons. Atmospheric ray tomography (ART) uses the muons and electrons for detecting objects and their composition. This paper presents new methods and a proof-of-concept tomography system developed for the ART of low-Z materials. We introduce the Particle Track Filtering (PTF) and Multi-Modality Tomographic Reconstruction (MMTR) methods. Based on Geant4 models we optimized the tomography system, the parameters of PTF and MMTR. Based on plastic scintillating fiber arrays we achieved the spatial resolution 120 µm and 1 mrad angular resolution in the track reconstruction. We developed a novel edge detection method to separate the logical volumes of scanned object. We show its effectiveness on single (e.g. water, aluminum) and double material (e.g. explosive RDX in flesh) objects. The tabletop tomograph we built showed excellent agreement between simulations and measurements. We are able to increase the discriminating power of ART on low-Z materials significantly. This work opens up new routes for the commercialization of ART tomography.
