摘要:

高分辨率蝇眼实验使用立体空气荧光技术测量了高能宇宙射线的通量。HiRes实验由两个探测器组成,通过它们发出的荧光观察宇宙射线簇射。HiRes数据可以在单目模式下进行分析,其中每个检测器单独处理,或者在立体模式下一起考虑。使用单目模式,HiRes合作测量了宇宙射线光谱,并首次观察到Greisen-Zatsepin-Kuzmin截止。本文介绍了用体视技术测量的宇宙线谱。与单目光谱在所有细节上都有很好的一致性。

英文摘要:

The High Resolution Fly's Eye experiment has measured the flux of ultrahigh energy cosmic rays using the stereoscopic air fluorescence technique. The HiRes experiment consists of two detectors that observe cosmic ray showers via the fluorescence light they emit. HiRes data can be analyzed in monocular mode, where each detector is treated separately, or in stereoscopic mode where they are considered together. Using the monocular mode the HiRes collaboration measured the cosmic ray spectrum and made the first observation of the Greisen-Zatsepin-Kuzmin cutoff. In this paper we present the cosmic ray spectrum measured by the stereoscopic technique. Good agreement is found with the monocular spectrum in all details.
