Light transport contribution to the timing characteristics of scintillation detectors
A Monte Carlo simulation of the light transit time in scintillation detectors is described, with the wavelength dependencies of different interaction processes being taken into account. The simulation results presented ...
Comparison of light transport-incorporated MCNPX and FLUKA codes in generating organic scintillators responses to neutrons and gamma rays
The NE102 plastic scintillator response to 137Cs gamma rays and NE213 liquid scintillator response to both mono-energetic and 241Am–Be neutrons have been modeled using FLUKA׳s EVENTBIN and MCNPX׳s PTRAC cards. The comparison ...
A plastic scintillator-based 2D thermal neutron mapping system for use in BNCT studies
In this study, a scintillator-based measurement instrument is proposed which is capable of measuring a two-dimensional map of thermal neutrons within a phantom based on the detection of 2.22MeV gamma rays generated via ...
On timing response improvement of an NE213 scintillator attached to two PMTs
A 5 cm diameter by 6 cm height NE213 scintillator attached to two XP2282 PHOTONIS photomultiplier tubes (PMTs) exposed to 241Americium–Berylium (Am–Be) neutron–gamma source has been used for timing response studies. The ...
On the necessity of light transport simulation in scintillators
In this study, the light transport simulation in scintillators is introduced, the wavelength-dependencies in the process are taken into account, the effect of different shapes/lengths of lightguides on the response of the ...
Light transport feature for SCINFUL
An extended version of the scintillator response function prediction code SCINFUL has been developed by incorporating PHOTRACK, a Monte Carlo light transport code. Comparisons of calculated and experimental results for ...
Digital neutron-gamma discrimination with scintillators: An innovative approach
In this paper, a digital neutron–gamma discrimination (DNGD) method with an NE213 scintillator has been proposed in which the anode pulse is divided into two different pulses, one representing the amplitude and the other ...
A comparison study on three different radiation detectors used for liquid levelmetry
In this paper, three different radiation detectors (BF3 counter, NE213 and BGO scintillators) and an 241Am–Be isotopic neutron–gamma source have been used for a typical liquid levelmetry. The study shows that the use of ...
A quantitative PGNAA study for use in aqueous solution measurements using Am-Be neutron source and BGO scintillation detector
A prompt gamma neutron activation analysis (PGNAA) system including an Am–Be neutron source and BGO scintillation detector are used for quantitative analysis of bulk samples. Both Monte Carlo-simulated and experimental ...
Numerical solutions for linear system of first-order fuzzy differential equations with fuzzy constant coefficients
In this paper, a novel iterative method is proposed to obtain approximate-analytical solutions for the linear systems of first-order fuzzy differential equations (FDEs) with fuzzy constant coefficients (FCCs) while avoiding ...
