On the optimum geometric shapes of ZnSe-based scintillation elements

摘要

We have carried out Monte-Carlo calculations of the light collection coefficient τ for different shapes of ZnSebased scintillators Applying a theoretical model, it has been shown, that the light collection optimization can beudreached in scintillators with a geometry where the chaotic light collection is realized. Experimentally it wasudsupported that for detectors of rectangular and cylindrical types with rounded vertexes or edges, the light outputudincrease of up to 20% has been observed, provided the regular light beam dynamics was changed to chaotic.
