摘要
大型液氩时间投影室（LArTPCs）正日益被用于中微子振荡实验，因为它们通过在全活性体积中结合径迹与量能测量而具有卓越的成像能力。位于或近地球表面的主动 LArTPC 中微子探测器，如 MicroBooNE 实验，由于宇宙线缪子的大通量和电离电子的慢漂移而带来独特的分析挑战。我们提出了一种在 MicroBooNE 中实现的基于 Wire-Cell 的新型高性能通用中微子探测技术。对于可见能量大于 200~MeV，宇宙线本底被压低了 1.4 倍，使得所选中微子候选事件中的宇宙线污染为 9.7\%，而在同一能量区域内，对 fiducial 体积中 带电流相互作用的中微子信号效率保持在 88.4\%。与现有重建算法相比，这一显著改进的性能标志着朝向实现近地球表面运行的 LArTPC 中微子振荡实验科学目标的一个重大里程碑。
