Proposal to Operate and Analyze Data from the High Resolution Fly's Eye Detector

9974537 Sokolsky这是一个操作高分辨率蝇眼（HiRes）天文台的建议。 这个探测器位于美国陆军位于犹他州的达格韦试验场，由两个相距12.7公里的站点组成。 它通过大气中的氮荧光探测超高能宇宙射线。 该观测站定于1999年夏季完工。 本提案适用于全面运营的前两年半。 该实验的目标是研究能量从10^18 eV到10^20 eV以上的宇宙射线的光谱、成分和各向异性。 以前的实验，包括最初的蝇眼实验，都证明了光谱在Greisen-Zatsepin-Kuzmin截止点后继续存在。截止点以上事件的性质是一个谜，激发了许多理论猜测。 HiRes探测器的灵敏度将比之前的Fly's Eye实验高出一个数量级。 该项目是犹他州大学、哥伦比亚大学、阿德莱德大学、新墨西哥州大学、加州大学洛杉矶分校和蒙大拿州立大学之间的一项合作项目，名为“ASPIRE”的教育推广计划，使犹他州的学生和教师能够通过因特网直接了解天体物理学的最新研究，并制作交互式联机物理课供K-12教室和远程学习使用。 ASPIRE活动由MPS物理部门和MPS多学科活动办公室（OMA）共同支持。

9974537SokolskyThis is a proposal to operate the High Resolution Fly's Eye (HiRes) observatory. This detector, located at the US Army's Dugway Proving Ground in Utah, is composed of two stations 12.7 km apart. It detects ultra high energy cosmic rays via nitrogen fluorescence in the atmosphere. The observatory is scheduled to be completed in the summer of 1999. This proposal is for the first 2 1/2 years of full operation. The goals of the experiment are the study of the spectrum, composition, and anisotropy of cosmic rays of energies from 10^18 eV to beyond 10^20 eV. Previous experiments, including the original Fly's Eye experiment, have shown evidence that the spectrum continues past the Greisen-Zatsepin-Kuzmin cutoff.The nature of the events above the cutoff is a puzzle which has stimulated much theoretical speculation. The HiRes detector will have an order of magnitude greater sensitivity than the previous Fly's Eye experiment. The project is a collaboration between the University of Utah, Columbia University, the University of Adelaide, the University of New Mexico, UCLA, and Montana State University.The educational outreach program, called "ASPIRE", provides direct access, via the internet, by Utah students and teachers to current research in astrophysics and produces interactive on-line physics lessons for use in K-12 classrooms and distance learning. The ASPIRE activity is supported jointly by the MPS Division of Physics and the MPS Office of Multidisciplinary Activities (OMA).
