Abstract
A control data about the devices constituting the synchrotron are formed by an initial acceleration control data item, a plural extraction control data items, a plural energy change control data items connecting the plural extraction control data items, and a plural deceleration control data items corresponding to the plural extraction control data items. An affected part position detection unit and an extraction permission determination unit are provided to determine whether the position of a marker shown in transparent image information is included within a beam irradiation permission range. If the marker position is found included, the extraction permission determination unit outputs to an interlock system an extraction permission determination signal permitting beam extraction.
