particle accelerator

n.
A device, such as a cyclotron or linear accelerator, that accelerates charged subatomic particles or nuclei to high energies for the purpose of colliding them with other particles or targets. Also called atom smasher.

particle accelerator

n
(General Physics) a machine for accelerating charged elementary particles to very high energies, used for research in nuclear physics. See also linear accelerator, cyclotron, betatron, synchrotron, synchrocyclotron

par′ticle accel`erator


n.
an electrostatic or electromagnetic device, as a cyclotron, that produces high-energy particles and focuses them on a target. Also called accelerator.
[1945–50]

particle accelerator

Any of several machines, such as the cyclotron and linear accelerator, that increase the speed and energy of protons, electrons, or other atomic particles and direct them at the nuclei of atoms, causing the nuclei to release new particles. Particle accelerators are used to study the atomic nucleus, to create radioactive isotopes, and to release elementary particles such as quarks. See Note at subatomic particle.
