摘要
Short-Baseline Neutrino Program 计划在 Fermi National Accelerator Laboratory 上的 Short-Baseline Near Detector (SBND)，距离 Booster Neutrino Beam 目标仅 110 米。正因为这种近距离相对于其 4 m 4 m 前面积的近 proximity，中微子从 到约 的一系列角度进入 SBND，这使探测器能够抽样中微子通量随角度变化的技术，称为 PRISM，此处称为 SBND-PRISM。在本文中，我们展示了 中子-和电中子通量如何随中微子束轴角度变化，以及如何利用这一点来扩充 SBND 的物理潜能。我们利用一种预测 脉冲振荡的角度相关电中子过量信号的模型来说明这一效果。我们展示了 SBND-PRISM 提供的方法，可用于增加对跨域建模不确定性的鲁棒性，更普遍地说，是针对不依赖于中微子相互作用发生在探测器内部位置的不确定性。通量及其相关协方差矩阵随本次出版物一并公开。
