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.)


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.


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
