This proposal addresses the need for funds to operate the Pierre Auger Observatory (PAO) for the next five years, starting in 2004. The objective of the PAO is to measure, with full sky coverage, the energy, direction and composition of the cosmic rays with energies above 10^19 eV. Large aperture cosmic ray observatories are opening a new window to the universe. To address this opportunity a broad based international collaboration has come together to build a very large air shower observatory that will make an all-sky study of cosmic rays at the highest energies. A number of cosmic rays with energies near and beyond 10^20 eV have been reported. Yet neither the origin of these cosmic rays nor the acceleration mechanism responsible for their enormous energies is known. The direct search for sources as well as the behavior of the energy spectrum above 5*10^19 eV will provide important clues to these mysteries. The PAO, located in Mendoza, Argentina, has completed the engineering phase and construction is underway and is expected to be complete by about the end of 2005 and to have a 20-year lifetime. The impact of the PAO has already gone well beyond the construction work and the capture of the first cosmic ray events. Close ties have been developed with branches of the National Technical University in Argentina where a number of students are involved, not only in building and testing equipment but in data taking tasks as well. In terms of outreach, the Visitor Center on the Auger campus has attracted more than 10,000 visitors from 26 countries. The collaboration sponsors a popular on-going lecture series for the public in the host city of Malargue and nearby communities. A particularly close relationship has been established with the people of Malargue. In the US, the PAO works closely with the CROP project based at the University of Nebraska that helps high school students install cosmic ray detectors on their schools.

这项建议涉及皮埃尔·俄歇天文台从2004年开始的今后五年的运作所需资金。 PAO的目标是在全天空覆盖的情况下测量能量超过10^19 eV的宇宙射线的能量、方向和成分。 大口径宇宙线观测站正在打开一扇新的宇宙之窗。 为了抓住这一机会，一个基础广泛的国际合作已经走到一起，建立一个非常大的空气簇射天文台，将在最高能量下对宇宙射线进行全天空研究。 一些能量接近和超过10^20 eV的宇宙射线已经被报道。 然而，这些宇宙射线的起源和产生巨大能量的加速机制都不为人所知。 直接寻找源以及5*10^19 eV以上能谱的行为将为这些谜团提供重要线索。 位于阿根廷门多萨的PAO已经完成了工程阶段，目前正在施工，预计将于2005年底完工，使用寿命为20年。PAO的影响已经远远超出了建造工作和捕获第一次宇宙射线事件。 与阿根廷国立技术大学的分校建立了密切的联系，许多学生不仅参与了设备的建造和测试，而且还参与了数据采集任务。 在外联方面，奥格校园的游客中心吸引了来自26个国家的10，000多名游客。 该合作赞助了一个受欢迎的正在进行的讲座系列为公众在主办城市马拉格和附近社区。 与马拉格人民建立了特别密切的关系。 在美国，PAO与内布拉斯加大学的CROP项目密切合作，帮助高中生在学校安装宇宙射线探测器。
