“…The simulated elements are the plastic scintillator (a BC-408 from Saint Gobain) and the Hamamatsu S10362-11-100U silicon photo-multiplier multi-pixel photon counter (MPPC). The BC-408 scintillator has a peak emission wavelength at 425 nm when ionized [14], with a yield reported to be around 10 000 photons/MeV [15], [16]. The Hamamatsu MPPC is composed of 100 square pixels with a width of 100 µm, which have a peak sensitivity (photon detection efficiency, PDE) of 65 % at around 440 nm.…”

An active shield using a scintillator and silicon photo-multipliers (SiPMs) has been developed to operate with space environment particle detectors sensitive to both protons and electrons, such as ICARE-NG (Influence sur les Composants Avancés des Radiations de l'Espace-Nouvelle Génération). The method shows a reduction in electron contamination through the sides of the detector, thus increasing energy resolution. Two geometries are studied, one working in coincidence mode with the main detector, the other in anti-coincidence. Performances of both geometries are simulated in proton and electron environments in energy ranges typical of a space environment. Experimental measurements then aimed to validate the Monte-Carlo simulation framework for scintillating materials. Lastly, a case study of electron decontamination is carried out, as well as an error rate estimation in flux reconstruction.

“…Scintillation occurs when a particle interacts with a crystal, and a device that measures and counts the scintillation is called a scintillation counter. The process of the reaction, amplification, and counting of the scintillation detector is shown in Figure 1 [24][25][26][27][28].…”

“…The liquid scintillation material is very effective when used to measure nuclides that emit low-energy alpha and low-energy beta rays (H-3, C-14, etc. ), as the detector can be manufactured in any size and shape and the measurement sample can be directly mixed with the scintillator [24,25].…”

Recently, nanomaterial-based scintillators are newly emerging technologies for many research fields, including medical imaging, nuclear security, nuclear decommissioning, and astronomical applications, among others. To date, scintillators have played pivotal roles in the development of modern science and technology. Among them, plastic scintillators have a low atomic number and are mainly used for beta-ray measurements owing to their low density, but these types of scintillators can be manufactured not in large sizes but also in various forms with distinct properties and characteristics. However, the plastic scintillator is mainly composed of C, H, O and N, implying that the probability of a photoelectric effect is low. In a gamma-ray nuclide analysis, they are used for time-related measurements given their short luminescence decay times. Generally, inorganic scintillators have relatively good scintillation efficiency rates and resolutions. And there are thus widely used in gamma-ray spectroscopy. Therefore, developing a plastic scintillator with performance capabilities similar to those of an inorganic scintillator would mean that it could be used for detection and monitoring at radiological sites. Many studies have reported improved performance outcomes of plastic scintillators based on nanomaterials, exhibiting high-performance plastic scintillators or flexible film scintillators using graphene, perovskite, and 2D materials. Furthermore, numerous fabrication methods that improve the performance through the doping of nanomaterials on the surface have been introduced. Herein, we provide an in-depth review of the findings pertaining to nanomaterial-based scintillators to gain a better understanding of radiological detection technological applications.

Abstract:In this research, different parameters of plastic scintillator detector were investigated by Geant4 simulation toolkit. These parameters consisted of radius, length and position of PMT as well as surface reflective type and finish options. Furthermore, response time distributions of two organic plastic materials were studied. The results indicated that collecting optical photons has a linear relationship with PMT radius head. Also, the vertical location of PMT has a non-linear relationship with the optical photons collection. However, the collection decreased by increasing PMT length or moving PMT head horizontal position. The response functions of two plastic scintillator materials were in good agreement with experimental published results. Also, Geant4 radiation transport code can simulate incident radiation photon and predict subsequent events to the PMT head very well. The results indicated that BC-404 has faster scintillation properties versus BC-400 organic scintillator materials. Comparison between Geant4 outputs illustrates that the best reflector material and surface finish type for optical photons is ground TiO 2 .
