Abstract
When accelerating charged particles on synchrotron acceleration basis by using a circular accelerator having a RF acceleration cavity, the detuned amount representative of an offset between oscillation frequency of a RF oscillator for the RF acceleration cavity and resoance frequency of the RF acceleration cavity and the RF power for supplying the charged particles with energy are controlled in compliance with changes in energy of the charged particles without changing the oscillation frequency. A great number of charged particles injected into the circular accelerator can be accelerated to the ultimate storage energy during the acceleration on synchrotron acceleration basis without causing charged particle beam loss.
