Spectrometric characteristics of polystyrene scintillation films

Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1999
Abstract The spectrometric characteristics of five types of polystyrene scintillation films with thicknesses of 10, 30, 50 and 80 μ m and of analogous 250 μ m thick plates irradiated with 239Pu, 238Pu and 226Ra sources of α-particles have been studied.

Optical and scintillation characteristics of Y2O3 transparent ceramic

Journal of Applied Physics, 2010
Various fundamental characteristics of Y2O3 ceramics, such as optical transmittance, reflectivity, absorption coefficient, refractive index, and dielectric constant, were investigated. Furthermore, in order to evaluate the possible application of this material as γ-ray scintillator, other radiation responses, like the α-ray excited emission spectrum ...

Attenuation characteristics of a Ce:Gd3Al2Ga3O12 scintillator

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2021
Abstract Attenuation characteristics of scintillation photons from Ce-doped Gd3Al2Ga3O12 (Ce:GAGG) scintillators were investigated by measuring samples of various sizes. Scintillation light is attenuated by two factors. The first is self-absorption of the Ce:GAGG scintillator itself, and the second is geometrical effects such as reflection properties

Liquid scintillators with advanced scintillation characteristics

Instruments and Experimental Techniques, 2010
Results of studying the influence of the component composition of liquid scintillators on their scintillation properties are presented. The correlation between the energy resolution and the peak-to-valley ratio in β-ray spectra is discussed. Compositions of fire-safe scintillation systems with characteristics above the generally accepted standard are ...

Scintillation characteristics of cosh-Gaussian beams

Applied Optics, 2007
By using the generalized beam formulation, the scintillation index is derived and evaluated for cosh-Gaussian beams in a turbulent atmosphere. Comparisons are made to cos-Gaussian and Gaussian beam scintillations. The variations of scintillations against propagation length at different values of displacement and focusing parameters are examined.

Characteristics of Scintillation Counters

Proceedings of the Physical Society. Section B, 1952
Experimental studies have been made of the distribution in size of output pulses from a scintillation counter detecting monoenergetic alpha-particles. Separate investigations have been made of contributions to the pulse size spread by the photomultiplier and by the scintillating crystal It is shown that the main effect is due to statistical ...

Performance and characteristics of a new scintillator

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1999
Abstract A new class of scintillators for neutron imaging, based upon lithium gadolinium borate, is described. These scintillators offer the ability to tailor their response to the neutron spectrum by varying the relative absorption of neutrons by the key constituents (lithium, gadolinium and boron).

Traps and Timing Characteristics of LuAG:Ce3+ Scintillator

physica status solidi (a), 2000
This note provides a direct comparison between YAP:Ce{sup 3+} and LuAG:Ce{sup 3+} scintillators grown in the same laboratory as for radioluminescence light output, scintillation decay and thermoluminescence characteristics. A correlation between the occurence of thermo-luminescence (TSL) peaks round RT and of very slow components in the scintillation ...

Characteristics of plastic scintillator granules

Journal of Applied Spectroscopy, 1967
Methods are described for measuring the absorption coefficient of the material, the absorption coefficient of a layer of granules, and the scintillation performance. The theory of light diffusion in a scattering medium is used and is compared with experiment.
