Measurement of the Cosmic Ray Energy Spectrum and Composition from 10^{17} to 10^{18.3} eV Using a Hybrid Fluorescence Technique
T. Abu-Zayyad, K. Belov, D. J. Bird +44
We study the spectrum and average mass composition of cosmic rays with primary energies between 10^{17} eV and 10^{18} eV using a hybrid detector consisting of the High Resolution…
A Multi-Component Measurement of the Cosmic Ray Composition Between 10^{17} eV and 10^{18} eV
T. Abu-Zayyad, K. Belov, D. J. Bird +45
The average mass composition of cosmic rays with primary energies between eV and eV has been studied using a hybrid detector consisting of the High Resolution Fly…
Study of Broad Scale Anisotropy of Cosmic Ray Arrival Directions from to from Fly's Eye Data
H. Y. Dai, B. R. Dawson, J. W. Elbert +9
We report results on the broad scale anisotropy of cosmic ray arrival directions in the energy rage from to . The data was taken by the Fly's Eye…
In Search of a Source for the 320 Eev Fly's Eye Cosmic Ray
Jerome W. Elbert, Paul Sommers
The 320 EeV air shower detected by the Fly's Eye poses an important problem. Careful analysis of pathlength limitations for the possible particle types due to cosmic background rad…
Detection of a Cosmic Ray with Measured Energy Well Beyond the Expected Spectral Cutoff due to Cosmic Microwave Radiation
D. J. Bird et al.
We report the detection of a 51-joule (320 +/- 90 EeV) cosmic ray by the Fly's Eye air shower detector in Utah. This is substantially greater than the energy of any previously repo…
