ABSTRACT:
A circular accelerator is arranged to circulate a charged particle beam through a bending function provided by a bending magnet, set a tune of the charged particle beam being circulated as it is betatron-oscillated to a predetermined value through the effect of a quadrupole magnetic field, resonate the charged particle beam being circulated at the tune set to the predetermined value in a manner to increase an amplitude of the betatron oscillations over the stability limit of resonance, thereby extracting the charged particle beam. The circular accelerator includes a bending magnet formed to generate a quadrupole magnetic field component for horizontally focusing the charged particle beam being circulated and vertically defocusing the beam and another bending magnet formed to generate a quadrupole magnetic field component for horizontally defocusing the charged particle beam being circulated and vertically focusing the beam. The accelerator is reduced in size, easily operated, and enables to keep the location of the beam extraction and the diameter of the beam constant and output an excellent charged particle beam.
