Observing cosmic ray neutrons. Background information, explanation of worldwide monitor network, detector description, publications, links.

An active research array for the detection of ultra-high energy cosmic rays. The events CHICOS is designed to observe are single subatomic particles slamming into the Earth's atmosphere with the energy of a brick falling from a rooftop. It is a collaboration of Los Angeles-area high schools, California Institute of Technology, California State University, Northridge, and University of California, Irvine.

Aims to observe the highest-energy cosmic rays.

Increased estimates of extragalactic magnetic fields may explain why possible HE CR sources, like AGN M87, do not align with observed CR directions.

Solar Tower Atmospheric Cherenkov Effect Experiment.

An experiment to detect energetic cosmic rays and gamma-rays. The goal was to measure the location, arrival direction, and energy of incoming cosmic rays and gamma-rays with energies above 10^14 eV, and to apply this information to investigate the origin cosmic rays and the nature of astrophysical source of the most energetic sources of gamma-rays. The project is no longer active, but some results (articles) are available.

Space-borne experiments like PAMELA, SilEye, NINA and balloons. Downloadable results, articles and pictures.
