Thermal neutron detection is a key subject for nuclear physics research and also in wide variety of applications from homeland security to medicine. In this work, it proposed novel flexible conformable composite thermal scintillator based on fully enriched Lithium Tetraborate preparation ([Formula: see text]Li[Formula: text]B[Formula: text]O[Formula: text]) combined with phosphorescent inorganic powder (ZnS:Ag), then distributed into polydimethylsiloxane matrix. The shows good efficiency...
The SiPM market has significant growth due to its expanding applications in fields like medical imaging and nuclear physics. With various manufacturers offering SiPMs, each with unique features, there is a need for evaluating their performances. This work conducts performance study of two medium-sized organic scintillators (EJ-309 EJ-276G) coupled arrays from three different brands (AdvanSiD-NUV hybrid, MPPC Hamamatsu S14161-6050HS-0, Ketek PA3325-WB-0404). Performance evaluation focused on...

Although the field of solar cells is most popular application perovskite materials, their use in radiation detection applications emerging. The success perovskites as detectors rests partly on same material properties that have led to successful optoelectronics applications, meaning other specific properties, like large stopping power, high mobility lifetime product, fast response, and bulk resistance, play a role. In this respect, inorganic are attracting lot attention scintillator...
This paper describes the characterization of a fast neutron facility located at Legnaro National Laboratories' Van de Graaff CN accelerator. The flux is produced by 9Be(p,xn) reactions, generated beryllium thick target bombarded with 5-MeV protons. An iterative unfolding algorithm combined pulse shape discrimination technique were used to obtain energy distributions emitted neutrons different angles and compute absolute as function proton current. With current 180 nA distance 5 cm from...
The superior photophysical and electronic properties of 2D hybrid metal halide perovskites (HPs), including large absorption coefficients, high photoluminescence yields, fast decay times, combined with stopping power mild temperature solution processing, make them promising candidates for next-generation scintillators.

The nuclear plant decommissioning and dismantling (D&D) operations will amount to €200 billion in costs over decades around the world, with three-fourths coming from Europe. Decommissioning includes activities such as planning, physical radiological characterization, facility site decontamination, dismantling, materials management. This work is focused on development of a compact, light low-power consumption neutron-gamma survey system which could be easily mounted an remotely operated...
The market for SiPMs has grown rapidly in recent years, driven by their increasing use applications such as medical imaging, nuclear and particle physics. Due to the growing demand, many manufacturers are now offering SiPMs, each of them with unique features performance characteristics. As a result, it is essential conduct comparative studies evaluate compare different SiPM arrays.
