Energy spectra of cosmic-ray nuclei at high energies (2009)
Ahn, H. S., Allison, P., Bagliesi, M. G., Barbier, L., Beatty, J. J., Bigongiari, G., ...
We present new measurements of the energy spectra of cosmic-ray (CR) nuclei from the second flight of the balloon-borne experiment Cosmic Ray Energetics And Mass (CREAM). The instrument included...
The Fluorescence Detector of the Pierre Auger Observatory (2009)
Abreu, P., Aglietta, M., Aguirre, C., Ahn, E. J., Allard, D., ...
The Pierre Auger Observatory is a hybrid detector for ultra-high energy cosmic rays. It combines a surface array to measure secondary particles at ground level together with a fluorescence detector...
IceRay: An IceCube-centered Radio-Cherenkov GZK Neutrino Detector (2009)
Allison, P., Beatty, J., Chen, P., Connolly, A., DuVernois, M., Gorham, P., ...
We discuss design considerations and simulation results for IceRay, a proposed large-scale ultra-high energy (UHE) neutrino detector at the South Pole. The array is designed to detect the coherent...

of the Pierre Auger Observatory requires accurate timing (25 nanoseconds or better) between measurements at individual detectors and instrument triggers. Timing systems for both SD and FD are based...
New Limits on the Ultra-high Energy Cosmic Neutrino Flux from the ANITA Experiment (2008)
Gorham, ANITA Collaboration: P., Allison, P., Barwick, S., Beatty, J., Besson, D., Binns, W., ...
We report initial results of the first flight of the Antarctic Impulsive Transient Antenna (ANITA-1) 2006-2007 Long Duration Balloon flight, which searched for evidence of a diffuse flux of cosmic...
Gorham, ANITA Collaboration: P., Allison, P., Barwick, S., Beatty, J., Besson, D., Binns, W., ...
We present a detailed report on the experimental details of the Antarctic Impulsive Transient Antenna (ANITA) long duration balloon payload, including the design philosophy and realization, physics...
