用KamLAND测量氙闪烁液中的cosmic-ray μ子散射产物
Measurement of cosmic-ray muon spallation products in a xenon-loaded liquid scintillator with KamLAND
摘要：
宇宙射线μ子在穿过物质时会产生各种放射性同位素。这些光谱产物可以作为稀有事件搜索的背景，例如太阳中微子、双β衰变和暗物质搜索实验。KamLAND-Zen实验在745 kg氙的液体闪烁体中寻找无中微子双β衰变。该实验包括无死时间的电子学，具有高效率的探测μ子诱导的中子。采用延迟符合技术、新发展的μ子重建和氙谱鉴别方法相结合的方法，测量了不同放射性同位素的产额。观测到的氙散射产物与FLUKA和Geant 4模拟程序的结果一致。
英文摘要：
Cosmic-ray muons produce various radioisotopes when passing through material. These spallation products can be backgrounds for rare event searches such as in solar neutrino, double-beta decay, and dark matter search experiments. The KamLAND-Zen experiment searches for neutrinoless double-beta decay in 745kg of xenon dissolved in liquid scintillator. The experiment includes dead-time-free electronics with a high efficiency for detecting muon-induced neutrons. The production yields of different radioisotopes are measured with a combination of delayed coincidence techniques, newly developed muon reconstruction and xenon spallation identification methods. The observed xenon spallation products are consistent with results from the FLUKA and Geant4 simulation codes.
