论文摘要
我们提出了一种估计分段计数器上撞击的颗粒数量或通常在带子单位的计数器上的颗粒数。我们几乎同时同时击中了两个或多个颗粒的效果，即未解决的颗粒。为了实现全职分辨率，我们解释了粒子信号的第一次倒数后发生的死时间。这种一般计数方法可以应用于在现有探测器中计数次数，例如Pierre Auger天文台的地下MUON检测器。因此，我们将后者用作研究案例来测试我们方法的性能并将其与文献中的其他方法进行比较。我们的方法证明是在很小的偏差中执行的，并且还提供了粒子数量作为时间的函数（检测器所见）到单个时间键分辨率的估计。在这种情况下，新方法可用于重建对宇宙射线质量敏感的参数，这对于揭示宇宙射线的起源是关键。
We present a general method for estimating the number of particles impinging on a segmented counter or, in general, on a counter with sub-units. We account for unresolved particles, i.e., the effect of two or more particles hitting the same sub-unit almost simultaneously. To achieve full time resolution we account for the dead time that occurs after the first time-bin of a particle signal. This general counting method can be applied to counting muons in existing detectors like the Underground Muon Detector of the Pierre Auger Observatory. We therefore use the latter as a study case to test the performance of our method and to compare it to other methods from literature. Our method proves to perform with little bias, and also provides an estimate of the number of particles as a function of time (as seen by the detector) to a single time-bin resolution. In this context, the new method can be useful for reconstructing parameters sensitive to cosmic ray mass, which are key to unveiling the origin of cosmic rays.
