#cyclotron  an accelerator that imparts energies of several million electron-volts to rapidly moving particles
  supertype:  particle_accelerator__accelerator__atom_smasher  a scientific instrument that increases the kinetic energy of charged particles
  subtype:  bevatron  a cyclotron that accelerates protons up to several billion electron volts
  subtype:  synchrocyclotron  cyclotron that achieves relativistic velocities by modulating the frequency of the accelerating electric field
  subtype:  synchrotron  cyclotron in which the electric field is maintained at a constant frequency
     subtype:  cosmotron  a large proton synchrotron; uses frequency modulation of an electric field to accelerate protons
