皮埃尔俄歇天文台的科学和探测器

Science and Detectors of the Pierre Auger Observatory

A. Etchegoyen

摘要:

宇宙射线的高能谱呈现出三个不同的特征,第二膝、踝和GZK截止,因此,对宇宙射线的透彻理解包括对这三个特征的研究。它位于第二个膝盖-脚踝区域,宇宙射线源从银河系起源变为河外起源。在较高的截止能量下,到达方向表现出与河外近区天空相关的各向异性。皮埃尔俄歇天文台目前的设计是通过以前所未有的精度进行光谱和成分测量来帮助解开这些特征。在第二个膝盖-脚踝区域的初级粒子类型将被研究与荧光望远镜和μ子计数器给出的空气簇射纵向剖面和μ子内容,分别。

英文摘要:

The high energy spectrum of cosmic rays presents three distinct traits, the second knee, the ankle, and the GZK cutoff and as such, a thorough understanding of cosmic rays encompasses the study of these three features. It is in the second knee - ankle region where cosmic ray sources change from a galactic origin to an extragalactic one. At the higher cutoff energies, the arrival directions show an anisotropy related to the near extragalactic sky. The Pierre Auger Observatory is currently designed to help to unravel these features by performing both spectrum and composition measurements with unprecedented accuracy. The primary particle type in the second knee - ankle region will be studied both with fluorescence telescopes and muon counters giving the air shower longitudinal profiles and muon contents, respectively.
