AI 中文摘要
基于闪烁体探测器的缪子成像技术可用于研究大型结构内部的密度分布。Hankuk大气缪子宽范围地形测绘（HAWL）项目是首个实时便携式缪子断层扫描技术，通过在移动车辆中运行探测器测量宇宙射线缪子，成功绘制了韩国东部山区的地图。HAWL实现了6.0%的隧道长度精度，覆盖层测量范围为8-400米水当量（m.w.e.）。HAWL升级版本（HAWLU）采用更紧凑的设计，具备轨迹重建能力。利用该升级系统，我们在保宁海底隧道中对潮汐水位变化进行了为期31.6天的测量，精度达米级。测量得到的缪子计数率随潮汐水位每升高1米下降1.72±0.04%，同时海底隧道扫描的轨迹重建结果独立验证了探测器的性能。这些结果证明了动态缪子成像技术在两种场景下的能力：一种是移动中的便携式探测器，另一种是测量随时间变化的目标。
英文摘要
Muography with scintillator-based detectors enables the investigation of density distributions within large structures. The Hankuk Atmospheric-muon Wide Landscaping (HAWL) project is the first real-time portable muon tomography. It successfully charted the mountainous region of eastern Korea by measuring cosmic-ray muons with a detector operated in a moving vehicle. HAWL achieved a tunnel length accuracy of 6.0 % and an overburden measurement range of 8-400 meter-water-equivalent (m.w.e.). The HAWL upgrade (HAWLU) features a more compact design and enables trajectory reconstruction. Using this upgraded system, we measured tidal water-level variations with meter-scale precision over 31.6 days in the Boryeong Undersea Tunnel. The measured muon rate decreased by $1.72 \pm 0.04$ % per meter of increasing tidal level, while the reconstruction of undersea tunnel scan independently validated the detector performance. These results demonstrate the capabilities of dynamic muography in two approaches, one with a portable detector in motion and the other with a detector measuring a target that changes over time.
