Contribution to the AugerPrime upgrade of the Pierre Auger observatory

该项目将支持对我们宇宙中最高能量粒子特性的基础研究，为3000平方公里的皮埃尔俄歇天文台的升级做出贡献。正在进行一项重大的探测器升级（AugerPrime），以提高观测站对这些高能宇宙射线的灵敏度。这是一个意想不到的俄歇结果，表明这些宇宙射线中有很大一部分由重核组成。AugerPrime将大大提高天文台识别粒子质量和电荷的能力，从而能够识别低电荷粒子的天体物理源方向，这些粒子较少被宇宙磁场偏转。这次升级还将提高对粒子物理学的理解，其能量远远超出大型强子对撞机的探索范围。

This project will support basic research into the properties of the highest energy particles in our Universe by contributing to the upgrade of the 3000 square kilometre Pierre Auger Observatory. A major detector upgrade (AugerPrime) is underway to enhance the sensitivity of the observatory for these high-energy cosmic rays. This follows an unexpected Auger result that indicates a significant fraction of these cosmic rays consist of heavy nuclei. AugerPrime will significantly improve the observatory's ability to identify the mass, and hence the charge, of the particles, allowing astrophysical source directions to be identified for the low charge particles which are less deflected by cosmic magnetic fields. The upgrade will also improve the understanding of particle physics at energies well beyond those explored at the Large Hadron Collider.
