摘要

利用4 × 4 （160 kg）塑料闪烁体探测器阵列构建了一个反应堆电子反中微子的原型探测器阵列，并运行了277 h的背景数据收集。首次对地表ibd样背景进行分析，事件率为397.4±20.3 day−1，相关ibd样背景事件率为137.42±10.05 day−1。表面上大多数类似ibd的背景事件都是由宇宙中子引起的。与宇宙中子相比，介子诱导的放射性同位素，如9Li和8He，以及介子诱导的中子的贡献微不足道。

Measurement of IBD-like background with plastic scintillator detector array at surface level

A prototype detector array for reactor electron antineutrinos is constructed using a 4 × 4 (160 kg) plastic scintillator detector array and operated for 277 h of background data collection. The first analysis of the IBD-like background at the surface is presented with the event rate of 397.4 ± 20.3 day⁻¹, with the correlated IBD-like background event rate being 137.42 ± 10.05 day⁻¹. The majority of IBD-like background events at the surface originate from cosmic neutrons. The contributions of muon-induced radioisotopes, such as ⁹Li and ⁸He, and muon-induced neutrons, are insignificantly small compared to cosmic neutrons.
