Abstract
A control method for an accelerator according to the present embodiment is a control method for an accelerator that supplies a current generating a magnetic field to a plurality of deflection electromagnets based on a current-value instruction signal. The method includes providing a flat region that makes a current value of the deflection electromagnet constant in a case of an acceleration cycle involving emission of the charged particles, not providing the flat region in the current-value instruction signal in a case of an acceleration cycle, smoothing time change of a current value in a transition of the current value to the flat region or a transition from the flat region, and determining a time required for the smoothing based on a predetermined energy for extracting the charged particles or a difference between energies before and after change to the predetermined extraction energy.
