“…Due to these favorable characteristics, the stilbene single-crystal scintillator has been used for many years as a fast neutron detector in the energy range of 500 keV to 20 MeV [10]. However, it is difficult to make a single-crystal stilbene scintillator larger than a few centimeters, and it is also prone to damage from thermal and mechanical shock [4,11]. The stilbene single crystals used in this study were grown using the Bridgeman-Stockbarger method [12], whose typical properties are presented in Table 1 [13].…”

Fast neutron applications have gained popularity with the growth of fast neutron production facilities. Covering a larger area and/or wider angle can be one of the advantages of a fast neutron detector. In the present study, a large-area composite stilbene scintillator with the dimensions of 200 mm (D) × 20 mm (H) was fabricated to examine its scintillation properties and to evaluate its applicability to fast neutron detection. The detector response of small-and large-area composite stilbene scintillators for neutrons and gamma rays was measured and compared with that of commercial and small single-crystal stilbene scintillators. To this end, the response of each scintillator was measured for radioisotopes as well as mono-energetic neutrons generated by a Tandem accelerator. The neutron-gamma separation performance of the largearea composite stilbene scintillator was evaluated in terms of figure-of-merit (FoM) using the digital pulse shape discrimination method. The composite stilbene scintillator showed good energy linearity, as determined from its recoil proton spectra, with reasonable n-γ separation capability. The results indicated that the composite stilbene scintillator could be applied to the field of fast neutron detection, especially when a large area and/or a wide angle is to be covered and could be a good alternative to liquid scintillators.

“…We called the materials of the first type (van der Waals ceramics) as organic polycrystals, and those of the second type as composite scintillators. The community started to study those ideas more actively after 2011, when it was proved that the unique properties are inherent to composite scintillators containing not only organic-scintillator grains, but also grains of inorganic scintillation crystals [3][4][5][6][7][8][9][10][11]. After our first publications, our colleagues from the Niederlands, the Republic of Korea (the South Korea), Poland, and the Russian Federation started to actively develop this problem.…”

COMPOSITE SCINTILLATORS AND SOME FEATURES OF THEIR RADIATION RESISTANCE PACS 42.88.+h, 81.05.Zx, 81.40.Wx Nowadays, composite scintillators find applications in a growing number of tasks dealing with the detection of ionizing radiation. They have several advantages in comparison with other scintillation materials. With the emergence of a new generation of accelerators, the radiation load on detectors is significantly increased. Therefore, the development of materials with high radiation resistance for radiation detectors becomes an important task. We propose to apply composite scintillators as radiation-resistant materials. The most important factor is that irradiation can significantly modify the characteristics of a scintillation material. The aim of this work was to study the specific features of possible radiation-induced damages and transformations in composite scintillators under the action of ionizing radiation. A comparative analysis of the relative light yield, transmittance, and luminescence spectra, as well as their dependences on the accumulated dose, is carried out for various composite scintillators containing grains of organic or inorganic single crystals, such as Gd2SiO5:Ce, Gd2Si2O7:Ce, Al2O3 : Ti, Y2SiO5:Ce, and Y3Al5O12:Ce. Probable mechanisms of radiation-induced changes occurring in scintillators under irradiation are proposed, and the influence of those processes on the radiation resistance of composite scintillators is analyzed.

“…Organic scintillators are widely used to detect these recoil protons. Fast neutrons in organic scintillators produce recoil protons through (n, p) elastic scattering and energy of a recoil proton at the highest level is equal to the energy of the neutron [1].…”

Several new methods for the digital discrimination of neutrons and gamma-rays in a mixed radiation field are presented. The methods introduced discriminate neutrons and gamma rays successfully in the digital domain. They are mathematically simple and exploit samples during the life time of the pulse, hence appropriate for field measurements. All these methods are applied to a set of mixed neutron and photon signals from a stilbene scintillator and their discrimination qualities are compared.
