Abstract 9617446 Gregory This award provides funds to continue the analysis of data acquired from the Japanese American Cosmic-ray Emulsion-chamber Experiment (JACEE) experiment over the past several years. JACEE has flown balloon borne payloads for long periods, up to 2 weeks, from McMurdo on paths which circumnavigate the pole. The experiments consist of stacks of photgraphic style emulsions which record the paths and interactions of energetic cosmic rays. The emulsions are developed once they are recovered from the ground, and by measuring the tracks, the isotopic mass of the elements which made them are determined. JACEE is one of the few experiments which is providing data on the elemental constituents of cosmic rays with energies near 10^15 eV, which will provide important information on the origin of cosmic rays. JACEE is a collaboration of NASA/MSFC, the Universities of Washington and Alabama, Louisiana State University and several institutions in Japan and Poland. The balloons, launch services and tracking were provided by NASA while the logistics, housing and payload recovery were provided by NSF's Office of Polar Programs. ***

摘要9617446格雷戈里该奖项提供资金，继续从日本美国宇宙射线乳胶室实验（JACEE）实验在过去几年中获得的数据分析。 JACEE已经从麦克默多绕极飞行了很长一段时间，长达2周。 这些实验由一堆摄影风格的乳剂组成，它们记录了高能宇宙射线的路径和相互作用。 一旦从地面回收乳胶，乳胶就会被开发出来，通过测量径迹，确定制造它们的元素的同位素质量。 JACEE是少数几个提供能量接近10^15 eV的宇宙射线元素成分数据的实验之一，这将提供关于宇宙射线起源的重要信息。 JACEE是NASA/MSFC、华盛顿大学和亚拉巴马大学、路易斯安那州立大学以及日本和波兰的几个机构的合作项目。 气球，发射服务和跟踪由NASA提供，而后勤，住房和有效载荷回收由NSF的极地计划办公室提供。 ***
