Image:Proton Collision Particle Tracks

Description: Computer illustration of subatomic particle tracks, in the style of a bubble chamber photograph showing tracks left by subatomic particles from a particle accelerator. A bubble chamber is a container filled with liquid hydrogen which is superheated. Any charged particle passing through the liquid in this state leaves behind a trail of tiny bubbles as the liquid boils in its wake. The bubbles are seen as fine tracks, which show the characteristic paths of different types of particle and which are curved due to an intense applied magnetic field. Scientists use data from these types of energetic subatomic collisions and the subsequent particle decay to investigate the structure of matter.
