Abstract
A circular accelerator for extracting a charged-particle beam is arranged to increase displacement of the beam by the effect of the betatron oscillation resonance and increase the betatron oscillation amplitude of the particles, which have initially betatron oscillation within the stability limit for the resonance, to exceed the stability limit thereby extracting the particles exceeding the stability limit of the resonance.
