Abstract
To reduce the number of steps of generating control pattern data needed for achieving beam irradiation with desired energy in the beam extraction from a synchrotron accelerator, a data generatordivides adjusted control pattern data, defines the divided data intervals as data modules, and reuses each of the data modules to generate new control pattern data. For extraction energy level changes, which are characteristic of multi-energy extraction, energy change control pattern data is generated based on the extraction pattern data before an energy level change and the extraction pattern data after the energy level change by using an interpolation function thereby to allow the control pattern data to be automatically generated. Effects of residual magnetic fields are calculated in advance, and then adjustment values that allow for the effects of the residual magnetic fields are incorporated into the control pattern data and operation is controlled.
