Air shower (physics)
Videos
Air showers are extensive cascades of subatomic particles and ionized nuclei, produced in the atmosphere when a primary cosmic ray enters the atmosphere. Particles of cosmic radiation can be protons,
Cosmic ray air shower created by a 1 TeV proton hitting the atmosphere 20 km above the Earth. The shower was simulated using the AIRES package. Animated 3D models of this and other showers can be found on COSMUS.
