论文摘要
IceCube是地理南极深层冰中的立方公里的Cherenkov探测器。深层冰探测器的主要事件产量包括在宇宙射线空气淋浴中产生的渗透性大气压，其能量高于300 GEV。此外，表面阵列，冰曲线测量了空气淋浴的电磁成分和GEV muons。因此，IceCube和Icetop产生了独特的机会，可以详细介绍具有前所未有的统计数据的宇宙射线。我们将从IceCube和Icetop中介绍漫画测量结果的最新结果。在此概述中，我们将重点介绍从250 TEV到EEV范围的宇宙射线的能量光谱，其质量组成在3 PEV上方。我们还将报告来自空气淋浴中灵恩含量的测量结果的最新结果，并讨论了它们与当前HADRONIC相互作用模型的预测一致性。
IceCube is a cubic-kilometer Cherenkov detector in the deep ice at the geographic South Pole. The dominant event yield in the deep ice detector consists of penetrating atmospheric muons with energies above approximately 300 GeV, produced in cosmic ray air showers. In addition, the surface array, IceTop, measures the electromagnetic component and GeV muons of air showers. Hence, IceCube and IceTop yield unique opportunities to study cosmic rays with unprecedented statistics in great detail. We will present recent results of comic ray measurements from IceCube and IceTop. In this overview, we will highlight measurements of the energy spectrum of cosmic rays from 250 TeV up to the EeV range and their mass composition above 3 PeV. We will also report recent results from measurements of the muon content in air showers and discuss their consistency with predictions from current hadronic interaction models.
