|a type of particle accelerator in which the particles spiral inside two D-shaped hollow metal electrodes placed facing each other under the effect of a strong vertical magnetic field, gaining energy by a high-frequency voltage applied between these electrodes|
|an extraordinary or unusual thing, person, or event; an exceptional example or instance.|

A type of particle accelerator that accelerates charged subatomic particles, such as protons and electrons, in an outwardly spiraling path, greatly increasing their energies. Cyclotrons are used to bring about high-speed particle collisions in order to study subatomic structures. Compare linear accelerator. See also synchrocyclotron. See Note at particle accelerator.
The first kind of particle accelerator built.
Note: Cyclotrons are now used for special research projects.
