The Northern Site of the Pierre Auger Observatory

摘要:

皮埃尔·奥格天文台是一个研究超高能宇宙射线的跨国项目。位于阿根廷门多萨省的南方俄歇天文台将于2007年完工,其仪器覆盖面积为3,000平方公里。它将精确测量超高能宇宙射线的光谱和成分,达到和超过预测的GZK特征。我们正在获得关于南天的能谱、质量组成和到达方向分布的结果。北部俄歇天文台的目的是完成和扩大在南部开始的调查。它将建立带电粒子天文学,从而打开一扇了解宇宙的新窗口。最高能量事件到达方向的分布将为揭开超高能宇宙射线的起源和性质的近百年之谜指明方向。实现这一目标需要收集更多的事件,尽管能量谱急剧下降。计划中的北部站点将在美国科罗拉多州东南部拥有4,000平方英里(10,370 km}^2)的仪器区域。本文介绍了带电粒子天文学、北俄歇天文台的布局和技术实现。

英文摘要:

The Pierre Auger Observatory is a multi-national project for research on ultra-high energy cosmic rays. The Southern Auger Observatory in Mendoza province, Argentina, is approaching completion in 2007 with an instrumented area of 3,000 km^2. It will accurately measure the spectrum and composition of ultra-high energy cosmic rays up to and beyond the predicted GZK feature. We are obtaining results on the energy spectrum, mass composition and distribution of arrival directions on the southern sky. The Northern Auger Observatory is designed to complete and extend the investigations begun in the South. It will establish charged particle astronomy and thus open a new window into the universe. The distribution of arrival directions of the highest energy events will point the way to unveiling the almost century old mystery of the origin and nature of ultra-high energy cosmic rays. Achieving this goal requires collecting many more events in spite of the steeply falling energy spectrum. The planned northern site will have an instrumented area of 4,000 square miles (10,370 km}^2 in Southeast Colorado, USA. The paper covers the science of charged particle astronomy, the layout and the technical implementation of the Northern Auger Observatory.
