论文摘要
Lhaaso KM2A由5915个闪烁探测器和1188个MUON探测器组成，MUON探测器覆盖了整个阵列的4％面积，其间距为30 m。使用MUON检测器记录的3/4 lhaaso阵列阵列记录的数据在2021年记录的空气淋浴事件数量，该数据在2021年记录。根据恒定强度切割方法，通过在各种Zenith角度将MUON数量的MUON数量的衰减长度与恒定的恒定量拟合。提出了衰减长度作为淋浴能量从数百个TEV到TENS PEV的变化。还提出了模拟结果以进行比较。
LHAASO KM2A consists of 5915 scintillation detectors and 1188 muon detectors, and the muon detectors cover 4% area of the whole array with 30 m spacing. The muon number of air shower events, with very high energy, is investigated with the data recorded by muon detector of the 3/4 LHAASO array in 2021. The attenuation length of muon number in the air shower is measured by fitting the muon number with constant flux in various zenith angles, based on the constant intensity cut method. The variation of the attenuation length as shower energy from hundreds TeV to tens PeV is presented. The results of simulation also is presented for comparing.
