摘要
SBND是一个位于Fermilab的112吨液氦气时间投影计数器（LArTPC）中微子探测器，距离Booste neutrino Beam（BNB）靶标仅110米。其主要目标包括作为Short-Baseline Neutrino（SBN）计划的一部分搜索eV尺度的中性粒子，以及其他探索标准模型之外物理的搜索，以及中微子-氦气相互作用的精度研究。此外，SBND为LArTPC中微子探测器技术开发提供了平台，是国际科学家和工程师团队的绝佳训练场，这些团队正为即将到来的旗舰性Deep Underground Neutrino Experiment（DUNE）做准备。SBND于2024年7月开始运行，于2024年12月以约7,000个中微子事件/天的前所未有的速率开始收集稳定中微子束数据。在当前批准的运行计划（2024-2027年）期间，SBND预计将累积近1000万个中微子相互作用。该近型探测器数据集将在SBN中以前所未有的灵敏度测试中立体中微子假设，并探寻标准模型之外物理信号。它还将用于显著提高我们对中微子-氦气相互作用物理理解，为DUNE做准备。计划于2029年后重新启动加速器后，正在探索在反中微子模式下运行SBND，以解决反中微子-氦气散射数据不足的问题，或以专用束流-抛射模式运行，以大幅提高对新物理探索的灵敏度。SBND是一个国际合作项目，约有40%的机构来自欧洲，参与探测器建设、调试、软件开发和数据分析。SBND运行和分析阶段的持续欧洲参与和领导对于SBND、SBN及其在DUNE中的作用至关重要。
