A cyclotron is a machine that uses magnetic fields to accelerate charged particles like protons to very high speeds in a spiral path. It matters because it can produce energetic particle beams useful for research and practical applications, as shown by the blue glow in this image where accelerated ions ionize the surrounding air.

A cyclotron is a type of particle accelerator invented by Ernest Lawrence in 1929–1930 at the University of California, Berkeley, and patented in 1932. A cyclotron accelerates charged particles outwards from the center of a flat cylindrical vacuum chamber along a spiral path. The particles are held to a spiral trajectory by a static magnetic field and accelerated by a rapidly varying electric field. Lawrence was awarded the 1939 Nobel Prize in Physics for this invention.
