The invention comprises a multi-axis charged particle irradiation method and apparatus. The multi-axis controls includes separate or independent control of one or more of horizontal position, vertical position, energy control, and intensity control of the charged particle irradiation beam. Optionally, the charged particle beam is additionally controlled in terms of timing. Timing is coordinated with patient respiration and/or patient rotational positioning. Combined, the system allows multi-axis and multi-field charged particle irradiation of tumors yielding precise and accurate irradiation dosages to a tumor with distribution of harmful proximal distal energy about the tumor.

The charged particle storage system includes: a storage ring circulating, by a perturbating device, charged particles injected from outside; a power source supplying an electric current to the perturbating device; and a charged particle beam generating device. The charged particle beam generating device includes a DC accelerator that generates a constant voltage to accelerate electrons and thereby generates a beam of the electrons. While a current having its current intensity changing in a sinusoidal wave is caused to flow through the perturbating device continuously for at least 10 s by a power source, an electron beam output from the charged particle beam generating device is injected to the storage ring continuously for at least 10 s. Thus, a current larger than that stored by the conventional resonance injection method can be stored in the storage ring, and an X-ray having higher intensity can be generated.

Provided are a charged particle beam generation apparatus, a charged particle beam irradiation apparatus, a particle beam therapy system, and a charged particle beam generation apparatus operating method capable of implementing injection of a charged particle beam into a circular accelerator at an arbitrary timing by setting a normal operation period of a linear accelerator to be larger than a shortest period and securing a stability of the beam. In timing control of controlling injecting, accelerating, emitting, and decelerating processes of a synchrotron (200), after an end of the emitting process, a linear accelerator (111) is allowed to stop repetition of an operation based on an after-end-of-emitting-process timing signal to be in a stand-by state and is allowed to be start the repetition of the operation in a constant period based on a master signal.
