cyclotron

/ˈsaɪkləˌtrɒn/
noun
1.
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

cyclotron in Science
cyclotron
  (sī'klə-trŏn')   

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.
