Electromagnetic particle shower. Particle tracks (moving from bottom to top) showing multiple electron-positron pairs created from the energy of a high-energy gamma ray photon produced by a neutrino collision. The positron is the anti-particle of the electron,and this process is called pair-creation. Electrons and positrons are charged particles and form these paired spirals as they curve away from each other in a magnetic field. As they do so,they radiate photons,which can in turn produce new electron-positron pairs. This shower of particle creation continues until the energy of the original photon is used up. The region shown here is about 2 metres tall | |
