The Model study on the Resonant Phenomena in Low Energy Proton Circular Accelerators with Intense Beams

The phenomena that proton passes through the integer and half–integer resonance points in low energy proton circular accelerator with intense beams are discussed.The manufacturing tolerances of the dipole magnet and quadruple magnet is given through simulations on the cases when the injection energy is 1MeV and the accelerating RF voltage per one turn is 1kV and 2kV, respectively. With these given manufacturing tolerances, particles can safely cross over the integer and half–integer resonant points.
