摘要
为了提取中微子振荡参数，精密长基线中微子振荡实验依赖于中微子与原子核相互作用的详细模型。这些模型是系统不确定性的重要来源，部分原因在于迄今为止的探测器对末态中子不可见。三维投影闪烁体径迹探测器是下一代长基线中微子实验近探测器的组成部分。由于良好的时间分辨率和精细的粒度，该技术能够在逐事件基础上测量中微子相互作用中的中子动能，并将为改进中微子相互作用模型以及重建中微子能量提供有价值的数据。2019 年和 2020 年，两个原型机在洛斯阿拉莫斯国家实验室（LANL）的中子束线上接受了能量介于 0 至 800 MeV 的中子照射。为展示中子探测能力，测量了总中子-闪烁体截面并与外部测量结果进行比较。在 98 至 688 MeV 之间测得的闪烁体总中子截面为 0.36 0.05 barn。
