cyclotron
 cyclotroncy·clo·tron C0837600 (sī′klə-trŏn′)n. A circular particle accelerator in which charged subatomic particles generated at a central source are accelerated spirally outward in a plane perpendicular to a fixed magnetic field by an alternating electric field. A cyclotron is capable of generating particle energies between a few million and several tens of millions of electron volts.cyclotron (ˈsaɪkləˌtrɒn) n (Atomic Physics) 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 electrodescy•clo•tron (ˈsaɪ kləˌtrɒn, ˈsɪk lə-)
n. an accelerator in which particles move in spiral paths in a magnetic field. [1930–35; cyclo- + -tron] ![]() cyclotronAn alternating electric field attracts the particles from one side of the cyclotron to the other. The cyclotron's magnetic field, generated by the two electromagnets, bends each particle's path into a horizontal spiral, forcing it to accelerate in order to keep up with the alternating electric field. When the particle reaches its peak acceleration it is released to collide with the desired target.cy·clo·tron (sī′klə-trŏn′) A device 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.

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.) 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 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
cy·clo·tron (sī'klō-tron), An accelerator that produces high-speed ions (for example, protons and deuterons) under the influence of an alternating magnetic field, for bombardment and disruption of atomic nuclei. Used to produce clinically useful positron-emitting radionuclides. [cyclo- + G. -tron, instrumental suffix] cyclotron Radiation therapy A device used to accelerate charged particles–eg, protons to higher energy levels, in which a magnetic field causes the particles to orbit, which are accelerated by an oscillating electric field. See Radiotherapy. cy·clo·tron (sī'klō-tron) A particle accelerator that speeds up particles in a spiral pattern to produce protons for nuclear research or radiation treatment. cy·clo·tron (sī'klō-tron) A particle accelerator that speeds up particles in a spiral pattern to produce protons for nuclear research or radiation treatment. cyclotron
