Chicago Air Shower Array (Physics)

该奖项将部分支持芝加哥空气簇射阵列(CASA)的运营，该阵列在过去三年中一直在美国国家科学基金会的资助下建设，位于犹他州Dugway的Fly‘s Eye II探测器现场。Casa的运行与密歇根大学达格韦分校建造的Muon阵列不谋而合。这些免费的阵列是同类阵列中最大和最灵敏的，将执行一项观测计划，以寻找超高能伽马辐射源(能量高于1014 eV)。这种源的发现将有助于解决几十年来关于高能宇宙射线起源的问题。

This award will partially support the operation of the Chicago Air Shower Array (CASA), which has been in construction for the last three years under an NSF grant and is located at the site of the Fly's Eye II detector at Dugway Utah. CASA operates is coincidence with a muon array built by the University of Michigan at Dugway. These complimentary arrays, the largest and most sensitive of their kind, will carry out a program of observations in a search for sources of Ultra High Energy gamma radiation (Energy above 1014 eV). The discovery of such source or sources would contribute to the resolution of the decades-old question of the origin of energetic Cosmic Rays.
