Antarctic Long Duration Balloon Flights for the JACEE Collaboration

摘要：Wefel该奖项为继续分析过去几年日美宇宙射线乳化室实验（JACEE）实验获得的数据提供了资金。JACEE已经从麦克默多绕北极飞行了很长时间，最长可达2周。实验由一堆照相风格的乳剂组成，这些乳剂记录了高能宇宙射线的路径和相互作用。乳剂一旦从地下被回收，就会被开发出来，通过测量轨迹，就可以确定构成乳剂的元素的同位素质量。JACEE是为数不多的提供能量接近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、华盛顿大学和阿拉巴马大学、路易斯安那州立大学以及日本和波兰的几个机构合作的项目。气球、发射服务和跟踪由美国宇航局提供，而后勤、住房和有效载荷回收由美国国家科学基金会的极地项目办公室提供。＊＊＊

Abstract 9614912 Wefel 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. ***
