Claim:
1. A charged particle beam generation apparatus comprising: a linear accelerator which is operated in a predetermined operation period and accelerates charged particles emitted from an ion source to emit a charged particle beam; a circular accelerator which is operated in an operation period including time intervals of injecting, accelerating, emitting, and decelerating processes for the charged particle beam, further accelerates and emits the charged particle beam accelerated in the linear accelerator, the charged particle beam being injected in a predefined timing; and a control device which, after an end of the charged particle beam emitting process in the operation period of the circular accelerator, generates an after-end-of-emitting-process timing signal, stops the linear accelerator based on the after-end-of-emitting-process timing signal, generates a synchrotron pattern start signal indicating a next operation start timing, and starts a periodic operation of the linear accelerator based on the synchrotron pattern start signal.
