用于高性能测量的有机/无机混合scintillator

A hybrid organic/inorgaic scintillator for high performance measurements

S. Wagner, M. Grassi, A. Cabrera

摘要:

中微子物理学领域新的实验研究计划要求新的探测器具有大质量、高能量分辨率和良好的背景抑制能力。本文提出了一种新型的混合有机/无机闪烁体,这是能够同时改善所有三个方面。这种闪烁体由悬浮在有机闪烁载体介质中的无机晶体的微观颗粒组成。由于晶体的多次散射,这种闪烁体在较长距离上看起来不透明,旨在用于专门的探测器。由于晶体相,它可以天然地包含大量的各种元素,因此足够大的检测器可以达到吨或多吨级的元素负载。同时,这种组合物可以产生非常高的光输出,并提供额外的颗粒识别能力。这种闪烁体的概念预计将为未来的中微子实验提供显着的优势,如无中微子双β实验和反应堆反中微子物理的搜索。

英文摘要:

New experimental research programs in the field of neutrino physics are calling for new detectors with large masses, high energy resolution and good background rejection capabilities. This paper presents a novel hybrid organic/inorganic scintillator, which is able to improve on all three aspects simultaneously. This scintillator consists of microscopic grains of inorganic crystals suspended in an organic scintillating carrier medium. Due to multiple scattering off the crystals, this scintillator appears opaque over longer distances and is intended for use in specialized detectors. Thanks to the crystal phase it can natively incorporate a large variety of elements in large quantities, so that a sufficiently large detector can reach elemental loadings on the ton- or multiton scale. At the same time, this composition can produce very high light outputs and provides additional particle identification capabilities. This scintillator concept is expected to provide significant advantages for future neutrino experiments, like searches of neutrinoless double beta experiments and reactor antineutrino physics.
