This project, which is a renewal of an ongoing effort, makes use of the ice sheet at South Pole to build a large detector of very high-energy astrophysical neutrinos. The detector was constructed between 1,400 and 2,400 meters below the surface by melting holes into the ice with a hot water drill and then freezing in long stings of widely space photomultiplier tubes. Occasionally upward going neutrinos, which have passed through the bulk of the Earth, interact in the ice, producing charged particles, the Antarctic Muon and Neutrino Detector Array (AMANDA), detects the resulting flash of light, from which the energy and direction of flight of the original neutrino can be deduced. Because neutrinos are so penetrating, and because they are not deflected by magnetic fields, they offer the opportunity to see inside of regions of the universe that are completely obscured from study by any other technique. The present detector has 19 strings in place, and this award will provide the manpower and equipment necessary to calibrate the strings that were installed in the austral summer of 1999/2000, maintain the detector and analyze the resulting data. It will also provide some funding toward advanced technology development aimed toward the possible eventual construction of a cubic kilometer detector, IceCube.AMANDA is a collaboration of the University of Wisconsin (this award), the Universities of California at Berkeley and Irvine, Lawrence Berkley national Laboratory (partly funded though this award), the Universities of Stockholm, Kalmar and Uppsula (Sweden), DESY, the Universities of Wuppertal and Mainz (Germany), and the Universities of Brussels and Mons (Belgium). The institutions other than Wisconsin and some of LBNL are funded through different channels. Within the US, this project is supported by DoE, and within NSF by the Division of Physics and the Office of Polar Programs.

这个项目是一项正在进行的努力的更新，它利用南极冰盖建造一个大型的高能天体物理中微子探测器。探测器是在地表以下1400米到2400米的地方建造的，方法是用热水钻在冰面上融化一些洞，然后把它们冻成一长串宽空间的光电倍增管。偶尔向上的中微子穿过地球的大部分，在冰中相互作用，产生带电粒子，南极μ子和中微子探测器阵列（AMANDA）探测到由此产生的闪光，从中可以推断出原始中微子的能量和飞行方向。由于中微子具有很强的穿透力，而且它们不会被磁场偏转，因此它们提供了观察宇宙内部区域的机会，而其他任何技术都无法对这些区域进行研究。目前的探测器有19根串，该合同将提供必要的人力和设备来校准1999/2000年南方夏季安装的串，维护探测器和分析结果数据。它还将为先进技术的开发提供一些资金，目的是最终可能建造一个立方公里的探测器——冰立方。AMANDA是威斯康星大学（该奖项）、加州大学伯克利分校和欧文分校、劳伦斯伯克利国家实验室（部分资金来自该奖项）、斯德哥尔摩大学、卡尔玛大学和乌普苏拉大学（瑞典）、DESY大学、伍珀塔尔大学和美因茨大学（德国）、布鲁塞尔大学和蒙斯大学（比利时）的合作项目。除了威斯康辛州和一些LBNL以外的机构通过不同的渠道获得资金。在美国，该项目由能源部支持，在美国国家科学基金会由物理部和极地项目办公室支持。
