Cosmic Ray Physics Laboratory

Physics, Science, Osaka City University

Japanese version is here

We are studying Ultra High Energy Cosmic Rays, which are High Energy Particles coming from Space. If a single particle has Ultra High Energy, it can create more than Million particles in the atmosphere. We call this phenomena as "Extensive Air Shower", and we observe them on the ground, high altitude mountain and deep underground. Cosmic Ray Physics is a boundary study between Particle Physics and Cosmology. There are so many mysteries of High Energy phenomena in Our Universe.
