Abstract The absolute values of the neutron response functions of a 12.7 cm diameter by 12.7 cm long NE213 organic liquid scintillator were measured using a quasi-monoenergetic neutron field in the energy range of 66– 206 MeV via the 7Li(p,n)7Be reaction in the ring cyclotron facility at RIKEN. The measured response functions were compared with calculations using a Monte Carlo code developed Abstract The neutron-gamma discrimination capability of the new-type UGLLT liquid scintillator has been compared with NE213 (or its Bicron equivalent, BC501A). An Am-Be combined neutron-gamma isotopic source and a zero-crossing circuitry were used to explore various biases resulting the optimum figure of merits (FOMs) of 1.52 and 1.18 for NE213 and UGLLT at 170 keVee bias, respectively. Abstract The parameters of a neutron detector with the NE213 liquid scintillator which filled teflon cuvettes of long sizes have been investigated. It is shown that light attenuation effects are considerably weaker for the teflon cuvette as compared to the glass cells with an “external” reflector. The value λ = 7–10 m has been obtained for the light absorption length in the NE213 NE213 liquid scintillator, presented as a contour ,(original photograph is a 16-color map) and an isometric display.

These are based on the property of most of the scintillator materials, such as the NE213, that exhibit a light pulse-shape characteristic of the ionizing radiation . In the present paper, the results obtained using the fast stretcher technique with a NE213 liquid scintillator are presented for the first time. Gamma-rays and neutrons coming from nuclear reactions induced by an accelerated beam are detected and discriminated.

The measurements have been performed on candidate mixtures for the low energy solar neutrino detector Borexino, as well as on the standard NE213 scintillator, specifically optimized for the PSD application. The description of the results will be complemented by a comparison of the characterization obtained with the two different methods.
