PLASTIC SCINTILLATOR DEVICE WITH PIECE COMPRISING SCINTILLATING HYBRID MATERIAL, ASSOCIATED MANUFACTURING AND MEASUREMENT METHOD, AND APPARATUS.

摘要

Device for detection by plastic scintillation comprising a part composed in whole or in part of a hybrid material comprising: a polymeric matrix; and a fluorescent mixture incorporated in the polymer matrix and comprising i) 80% to 99.6 mol% of a primary primary fluorophore consisting of naphthalene and ii) 0.4% to 20 mol% of an additional primary fluorophore of which the centroid of the light absorption spectrum and the fluorescence emission spectrum, the fluorescence decay constant and the fluorescence quantum efficiency are judiciously chosen; the part being coupled to an electronic acquisition module capable of collecting the radioluminescent radiation emitted by the part when it is in contact with an ionizing radiation or an ionizing particle. The fluorescence decay constant of the hybrid material composing the part of the device is intermediate between that of a fast plastic scintillator material and a slow plastic scintillator material. In addition, it can be chosen in a wide range. The invention also relates to the method of manufacture and measurement associated and an apparatus comprising the device.
