The effect of magnetic field on the scintillation efficiency of organic scintillators
Acta Physica Hungarica, 1992The fluorescence of different organic plastic and liquid scintillators has been measured as a function of magnetic fieldH up to 13 mT (milli tesla). In the case of NE213, NE230 and stilbene, the percentage change in scintillation efficiency ΔE(%) increases with increasingH till it becomes maximum at an optimum valueH m, and then it ...

The scintillation decay of some commercial organic scintillators
Nuclear Instruments and Methods, 1965Abstract The scintillation decay of some commercial available organic scintillators has been studied on the interval 0–100 ns by a delayed coincidence method. The results of the measurement indicate that on the investigated time interval the scintillation decay of most organic scintillators contains two exponential components, the longer decay time ...

Molecular origins of scintillation in organic scintillators (Conference Presentation)
Low-Dimensional Materials and Devices 2016, 2016Organic-based scintillators are indispensable materials for radiation detection owing to their high sensitivity to fast neutrons, low cost, and tailorable properties. There has been a recent resurgence of interest in organic scintillators due to exciting discoveries related to neutron discrimination and gamma-ray spectroscopy, which represent ...

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 ...
