An ion implantation method includes acquiring a first data set for setting beam energy of an ion beam output from the high energy multi-stage linear acceleration unit to be a first output value, determining a second data set for setting the beam energy of the ion beam output from the high energy multi-stage linear acceleration unit to be a second output value different from the first output value, based on the first data set, and performing ion implantation by irradiating a workpiece with the ion beam output from the high energy multi-stage linear acceleration unit operating in accordance with the second data set. An acceleration phase of the high frequency accelerator in each of the plurality of stages is the same between the first data set and the second data set, in all of the high frequency accelerators respectively in the plurality of stages.
