Multiscale Approach to Estimation of Scintillation Characteristics

IEEE Transactions on Nuclear Science, 2014
This work is directed to analysis and description of the factors which determine the efficiency of inorganic scintillators. The interconnection of different stages of track formation and relaxation is analyzed. The hierarchy of the scales of different processes in scintillators is discussed.

Scintillation characteristics and imaging performance of CsI:Tl thin films for X-ray imaging applications

Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2009
We have manufactured thallium-doped cesium iodide (CsI:Tl) scintillator thin films by the thermal deposition method. The scintillation characteristics of the CsI:Tl thin films were studied by X-ray-induced luminescence for different Tl doping ...

A study of the characteristics of CeF3 scintillating crystals

Instruments and Experimental Techniques, 2000
The properties of cerium trifluoride scintillating crystals, grown in Russia using the Stockbarger's method, were investigated. The characteristics of CeF3, PbWO4, Bi4Ge3O12, and BaF2 crystals were compared for use in electromagnetic calorimeters to detect electrons and γ-rays of medium and high energies.

Characteristics of solgel scintillators for liquid scintillation counting of aqueous and non-aqueous samples

The International Journal of Applied Radiation and Isotopes, 1976
Abstract The performance of solgel scintillators in the radioassay of acid, base and neutral aqueous samples is discussed in detail. These scintillators are shown to be outstanding for both aqueous and non-aqueous samples. A two-phase colloidal system where the effective micelle size of the aqueous phase is negligibly small, compared to the range of ...

Organic Polycrystalline Scintillators with Improved Characteristics

Instruments and Experimental Techniques, 2003
The properties of organic polycrystalline scintillators produced by different methods are studied. It is shown that polycrystals in the shape of plates, made by compacting powders of solution-grown organic crystals at premelting temperatures, exhibit better characteristics. Their energy resolution for α and β particles is higher by 40% and, for X-rays,

[Luminescence Characteristics of Scintillator Y2SiO5∶Ce].

Guang pu xue yu guang pu fen xi = Guang pu, 2018
Cerium doped Y2SiO5 (YSO) is an important scintillator material due to its high density, non-hygroscopic, excellent light output and fast decay time nature. in the paper, Y2SiO5∶Ce3+0.2%(YSO∶Ce) was grown with high-temperature solid-phase method. The time-resolved excitation and emission spectra and fluorescent decay curves at low temperature and room ...

Characteristics of Liquid-Scintillation α Spectrometry

Atomic Energy, 2002
The energy calibration curve in the α-particle energy range 4.01–8.77 MeV, suitable for solutions of a liquid scintillator with different light absorption, is constructed. The mechanisms of broadening and asymmetry of the α peaks of various actinides are studied.

Luminescence Characteristics of Some Scintillating Crystals

Proceedings of the Physical Society. Section B, 1954
The phosphorescence observed during the period 2 to 400 μsec following the absorption of gamma-ray photons has been studied in crystals of sodium iodide and potassium iodide (thallium activated) and calcium tungstate. The integrated light output is found to vary with temperature over the range - 180°c to + 15°c in a complex manner differing with each ...

Influence of surface treatment conditions for organic crystalline scintillators on their scintillation characteristics

2019
The scintillation and optical characteristics of alpha and beta radiation detectors based on organic crystalline scintillators are investigated after the treatment of their surfaces with different compositions. The polishing composition has been matched, which ensures an improvement in the quality of the polished surface and an improvement in the ...
