Title:
ACCELERATOR AND PARTICLE BEAM IRRADIATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/096648
Kind Code:
A1
Abstract:
In this accelerator 50, a main magnetic pole 1 has a recess 1B in the surface that is on the side of an outer peripheral surface 1A which faces away from the surface opposing another main magnetic pole 1. In an ion source 3, a discharge chamber 105 and a magnetic path 103 are disposed more inward than the outer peripheral surface 1A of the main magnetic pole 1 when the main magnetic pole 1 is viewed from a vertical direction cross section. In other words, the discharge chamber and the magnetic path are disposed in the recess 1B of the main magnetic pole 1. In this manner, a beam line can be shortened, providing an external ion source type accelerator that does not use a large-scale device, and a particle beam irradiation device equipped therewith.
