A cyclotron


This is a simulation of a cyclotron, which is a very compact particle accelerator. In the D-shaped sections (these are called dees) there is a uniform magnetic field that makes the positively charged particle follow a path that is a half circle. Each of these half circles brings the particle back to the gap between the dees, in which there is an electric field that accelerates the particle across the gap. Eventually, the particle comes flying out of the cyclotron at high speed.
