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

9974537索科尔斯基这是一项运营高分辨率苍蝇眼(HERS)天文台的提议。该探测器位于犹他州美军杜格威试验场，由相距12.7公里的两个站点组成。它通过大气中的氮气荧光探测超高能宇宙射线。天文台预计于1999年夏季建成。这项建议是为全面运行的头两年半提出的。该实验的目标是研究从10^18 eV到10^20 eV以上能量的宇宙射线的光谱、组成和各向异性。之前的实验，包括最初的苍蝇眼实验，已经表明光谱在Greisen-Zatsepin-Kuzmin分界点之后继续存在。分界点以上事件的性质是一个谜团，引发了许多理论猜测。HiRes探测器的灵敏度将比之前的Fly‘s Eye实验高一个数量级。该项目是犹他大学、哥伦比亚大学、阿德莱德大学、新墨西哥大学、加州大学洛杉矶分校和蒙大拿州立大学的合作项目。该教育推广计划名为“ASPIRE”，让犹他州的学生和教师通过互联网直接接触到当前的天体物理学研究，并制作互动的在线物理课程，供K-12课堂和远程学习使用。APIRE活动由公安部物理司和公安部多学科活动办公室(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).
