Abstract

The Large-Volume scintillation Detector commonly known as LVD and located at the Gran Sasso Laboratory at an average depth of 3650 m w.e. measures muons of intensity \(3.31\times 10^{-4}\) m\({}^{-2}\) s\({}^{-1}\). The results obtained from an analysis of the properties of seasonal variations of the horizontal and vertical muon fluxes are presented in this article. Horizontal muons detected in LVD mostly correspond to rock depths of about 5 km w.e. and zenith angles \(\theta\) of about \(75^{\circ}\), while vertical muons (\(\theta\approx 13^{\circ}\)) correspond to depths of about 4.6 km w.e.

用地下LVD装置测量水平μ子的季节性变化

摘要

大容量闪烁检测器通常称为LVD，位于Gran Sasso实验室，平均深度为3650 m，我们可以测量μ \（3.31 \乘以10 ^ {-4} \）  m \（{} ^ {- 2} \）  s \（{} ^ {-1} \）。本文介绍了通过对水平和垂直μ子通量​​的季节性变化特性进行分析而获得的结果。在LVD中检测到的水平μ子大体上对应于大约5 km we的岩石深度和大约\（75 ^ {\ circ} \）的天顶角\（\ theta \），而垂直μ子（\（\ theta \约13 ^ { \ circ} \））对应于大约4.6 km的深度
