本文介绍了用于COSINE-100暗物质实验的液体闪烁体否决系统及其性能。COSINE-100探测器由8个NaI（Tl）晶体浸在2200 L线性烷基苯基液体闪烁体中组成。液体闪烁体在2-6 keV能量区域内标记65 - 75%的内部40k背景。我们还描述了液体闪烁体的背景模型，该模型主要用于评估其能量校准和阈值。
This paper describes the liquid scintillator veto system for the COSINE-100 dark matter experiment and its performance. The COSINE-100 detector consists of eight NaI(Tl) crystals immersed in 2200 L of linear alkylbenzene-based liquid scintillator. The liquid scintillator tags between 65 and 75% of the internal40K background in the 2-6 keV energy region. We also describe the background model for the liquid scintillator, which is primarily used to assess its energy calibration and threshold.
