The ability to simultaneously identify the direction of both fast neutrons, above 1 MeV, and gamma rays using a light-weight system consisting single 1” EJ-309 organic liquid scintillator plastic Spartan rotating scatter mask (RSM) is demonstrated computationally through Monte Carlo simulations validated with experimental measurements. Two sets directional measurements were performed an americi...

Abstract In this study, the anti-noise performance of a pulse-coupled neural network (PCNN) was investigated in neutron and gamma-ray ( n − $$\gamma$$ γ ) discrimination field. The experiments were conducted two groups. first group, radiation pulse signals pre-processed using Fourier filter to reduce original...

Pulse shape discrimination (PSD)-capable plastic scintillator is in demand for the detection of high-energy neutrons presence gamma radiation background. Conventional PSD plastics are based on delayed fluorescent dye via triplet–triplet annihilation a additive, which inefficient to harvest energy triplet excitons. In recent years, thermally activated fluorescence (TADF) emitters have gained sub...

The aim of this study was to investigate whether the amplitude of gamma-band activity is influenced by the factor age. We examined alpha- and gamma-band EEG activity and event-related potentials (ERPs) of 12 subjects. Six subjects constituted the younger (mean age=36.6 years) and another six the older age group (mean age=47.6 years). Subjects performed a visual discrimination task which require...
