cyclotron: see particle accelerator particle accelerator, apparatus used in nuclear physics to produce beams of energetic charged particles and to direct them against various targets. Such machines, popularly called atom smashers, are needed to observe objects as small as the atomic nucleus in studies

cyclotron

Particle accelerator that accelerates charged atomic or subatomic particles in a constant magnetic field. It consists of two hollow semicircular electrodes, called dees, in a large evacuated cylindrical box. An alternating electric field between the dees continuously accelerates the particles from one dee to the other, while the magnetic field guides them in a circular path. As the speed of the particles increases, so does the radius of their path, and the particles spiral outward. In this manner, a cyclotron can accelerate protons to energies of up to 25 million electron volts.


cyclotron
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 [′sī·klə‚trän]
(nucleonics)
An accelerator in which charged particles are successively accelerated by a constant-frequency alternating electric field that is synchronized with movement of the particles on spiral paths in a constant magnetic field normal to their path. Also known as phasotron.

Cyclotron 

a resonance particle accelerator in which the magnetic guide field and the frequency of the accelerating electric field are constant in time. The particles, which may be protons or heavier ions, move in an uncoiled spiral. The highest possible energy of protons accelerated in a cyclotron is about 20 million electron volts and may reach 1 billion electron volts in an isochronous cyclotron. (SeeACCELERATOR, PARTICLE.)
