Recent progress of organic scintillators
Japanese Journal of Applied Physics, 2022Abstract Recent development of organic scintillators is reviewed from the viewpoint of materials science. Design and crystal growth of organic crystalline scintillators, use of novel solvents and solutes in liquid scintillators, and development of plastic scintillators based on novel polymer hosts or novel fluorescent molecules are ...

Rise time of scintillation emission in inorganic and organic scintillators
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1997Abstract Theoretical aspects of the rise time of the scintillation in inorganic and organic scintillators and the dependence on the particle energy are discussed. The results are compared with published experimental data.

A setup for measuring the scintillation parameters of liquid organic scintillators
Journal of InstrumentationAbstract Setups have been developed and constructed to study the main scintillation properties, such as light yield and emission kinetics, of liquid organic scintillators used in neutrino physics and astroparticle physics experiments. The measurement results of the main characteristics of these setups are presented in this work.

Gamma calibration of organic scintillators
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989Abstract The electron light responses of three organic scintillator detectors – a stilbene (3.81 × 1.27 cm2) and two NE102A (5.0 × 2.5 cm2 and 5.0 × 7.6 cm2) — were systematically studied by means of a set of gamma sources. The edge maximum and half-height point energies of the Compton distributions have been determined by the use of a fast/slow ...

Organic scintillators for neutron detection
SPIE Proceedings, 2003The goal of the present work has been to develop a method for the efficient and reliable production of gadolinium- and boron-containing solid scintillator. Polyvinyl toluene, silicone rubber, and other materials were investigated. Gadolinium in a solid overcomes the limitations of the physical form of a liquid, and silicone rubber as a carrier for ...

The Scintillation Process in Organic Systems
IRE Transactions on Nuclear Science, 1960The scintillation process in organi: crystals and solutions is described, and a mechanism is proposed to account for the origin of the fast and slow scintillation components. The intermolecular energy migration and transfer processes in pure and mixed crystals and in plastic and liquid solutions are discussed quantitatively, and the influence of ...

The Origin of Scintillations in Organic Materials
IRE Transactions on Nuclear Science, 1960Calculations of the energy expended by a charged particle in producing optical excitation of molecules of the scintillator indicate the possibility that most of the energy emitted as light during a scintillation may stem, either directly or via intermolecular transfer, from molecules excited in this way.

The luminescence decay of organic scintillators
Molecular Crystals, 1968Abstract Results obtained in the laboratory on the luminescence decay of organic scintillators are reviewed. Theoretical equations, resulting from an analysis of the scintillation process, are shown to be in good agreement with experimental decay curves obtained with crystals and liquid scintillators.
