PARTICLE ACCELERATOR, PARTICLE BEAM RADIATION THERAPY DEVICE, AND METHOD FOR EMITTING CHARGED PARTICLE BEAM

WIPO Patent Application WO/2020/184232

A1

Provided is a small particle accelerator. A particle accelerator 20 comprises deflecting electromagnets 21 for deflecting a charged particle beam in a direction along an orbiting trajectory, and causes the charged particle beam to orbit and be accelerated and emitted. The particle accelerator 20 is provided with: a first-stage emission deflector 27 which causes the charged particle beam to be deflected in a separating direction away from the trajectory of the orbit; a middle-stage emission deflector 28 which causes the charged particle beam that has been deflected in the separating direction to be deflected in an approaching direction toward the trajectory of the orbit; and a later-stage emission deflector 29 which causes the charged particle beam that has been deflected in the approaching direction to be further deflected. At least one deflecting electromagnet 21 is provided between the middle-stage emission deflector 28 and the later-stage emission deflector 29. The first-stage emission deflector 27 and the middle-stage emission deflector 28 are accommodated in a single vacuum container 27c.
