This grant will fund the development and construction of specialized operational test and calibration sources for liquid scintillation detectors, as well as monitoring methods for scintillator properties at several meter pathlengths. The requirements are geared to match those of large scintillator based neutrino detectors where radiopurity and security against contamination are of paramount importance.Particular focus is given to developing aspects of a calibration and monitoring scheme for the Borexino solar neutrino detector, whose principle purpose is to measure the solar Be-7 neutrino flux. The primary avenue being pursued is an internal, encapsulated, radioactive source. The program is integrated with other calibration efforts of the Borexino collaboration.

这笔赠款将资助液体闪烁探测器专用操作测试和校准源的开发和建设，以及几米光程闪烁体特性的监测方法。 这些要求旨在与基于大型闪烁体的中微子探测器的要求相匹配，其中放射性纯度和防污染安全性至关重要。特别关注开发 Borexino 太阳中微子探测器的校准和监测方案的各个方面，其主要目的是测量太阳 Be-7 中微子通量。 所追求的主要途径是内部封装放射源。该计划与 Borexino 合作的其他校准工作相结合。
