Abstract 9528559 Morse 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 is being constructed between 1,400 and 2,100 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. On the rare occasions when very penetrating 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. The present detector has eight string in place, and this award will provide the manpower necessary to expand AMANDA to 20 strings and to analyze the resulting data. AMANDA is a collaboration of the University of Wisconsin (this award), the Universities of California at Berkeley and Irvine, the Universities of Stockholm and Uppsula (Sweden), and DESY (Germany). The institutions other than Wisconsin are funded through different channels. The hardware for the new equipment has already been provided for by a FY95 NSF Academic Research Infrastructure award and by the foreign funding agencies. ***

摘要9528559莫尔斯这个项目是正在进行的努力的更新，利用南极的冰盖建造一个巨大的超高能天体物理中微子探测器。探测器是在地表以下1400米到2100米之间建造的，方法是用热水钻头在冰中融化孔洞，然后将其冻结在空间广阔的长长的光电倍增管中。在极少数情况下，穿透地球大部分的向上穿透的中微子在冰中相互作用，产生带电粒子，南极缪子和中微子探测器阵列(阿曼达)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。目前的探测器有八根弦，这项奖励将提供必要的人力，将阿曼达扩大到20根弦，并分析产生的数据。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、瑞典斯德哥尔摩大学和乌普苏拉大学以及德国DESY大学合作的项目。威斯康星州以外的机构通过不同的渠道获得资金。新设备的硬件已经由95财年NSF学术研究基础设施奖和外国资助机构提供。***
