Abstract

The IceCube Observatory includes both a deep in-ice array of 86 strings of sensors, and a surface array of 81 stations of frozen water tank detectors (IceTop). These multiple detectors make it possible to measure different cosmic ray air shower components, and to combine these measurements to determine both the spectrum and composition of cosmic rays. This work focuses on two analyses of 3 years of IceCube/IceTop data, from 2010–2013. In one, IceTop alone is used to measure an all-particle spectrum using an assumed composition model. In the other, coincidence events which trigger both IceTop and IceCube are used to create individual spectra for four different nuclear groups (protons, helium, oxygen, and iron).

IceTop和IceCube三年的宇宙射线光谱和成分

摘要

IceCube天文台不仅包括86串传感器的冰深阵列,还包括81个冷冻水箱探测器(IceTop)的地面阵列。这些多个检测器使得可以测量不同的宇宙射线空气喷淋组件,并将这些测量值组合在一起以确定宇宙射线的光谱和成分。这项工作侧重于对从2010年至2013年3年的IceCube / IceTop数据进行的两次分析。在其中之一中,仅使用IceTop即可使用假定的成分模型来测量全粒子光谱。另一方面,同时触发IceTop和IceCube的巧合事件用于创建四个不同核组(质子,氦,氧和铁)的单独光谱。
