Title:
ELECTRIC CHARGE PARTICLE BEAM IRRADIATION SYSTEM
Document Type and Number:
Japanese Patent JP2018020163
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric charge particle beam irradiation system capable of shortening an irradiation time of an electric charge particle beam to an irradiation object.SOLUTION: The electric charge particle beam irradiation system includes: an electric charge particle beam generating device which accelerates an electric charge particle beam; an irradiation device 5 which emits the accelerated electric charge particle beam to a plurality of irradiation spots; a beam dose measurement device 59 which obtains a dose of the electric charge particle beam passing in the irradiation device 5; and a beam position measurement device 58 which obtains both or either the position and/or the width of the electric charge particle beam. The beam position measurement device 58 obtains both or either the position and/or the width of the electric charge particle beam per irradiation spot and determines whether it is within an acceptable range. Furthermore, it obtains both or either the position and/or the width of the electric charge particle beam per split and determines whether it is within an acceptable range regarding splits set by dividing all or a part of the plurality of irradiation spots into a plurality of irradiation sections to manage the dose.SELECTED DRAWING: Figure 2
