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.

2016-12-21 · The organic liquid scintillator NE-213 has been a popular detector medium since its introduction in the early 1960 s . It is a solution of aromatic molecules suspended in a xylene solvent. 1 The result is a flammable, corrosive, sharp-smelling liquid with a flash point of ∼ 26 ° C that poses a considerable health risk.
