Title:
荷電粒子加速器及び粒子線治療装置
Document Type and Number:
Japanese Patent JP5766304
Kind Code:
B2
Abstract:
The objective is to obtain a charged particle accelerator where the amount of pattern data for operating an acceleration cavity and electromagnets based on time clocks is reduced and the pattern data communication time is shortened. An accelerator control apparatus (25) provided in a charged particle accelerator (54) of the present invention is characterized by including a clock generation unit (18) that generates an acceleration cavity clock and an electromagnet clock that is synchronized with the acceleration cavity clock and has a frequency lower than that of the acceleration cavity clock; a high-frequency control unit (19) that controls an acceleration cavity (11), based on an acceleration cavity pattern stored in a first pattern memory (5) and the acceleration cavity clock; and a deflection electromagnet control unit (20) that controls a deflection electromagnet (15), based on a deflection electromagnet pattern stored in a second pattern memory (12) and the electromagnet clock.
