Charged particle deflecting device, charged particle irradiating device, charged particle accelerator, and method of manufacturing a charged particle deflecting device

摘要

PROBLEM TO BE SOLVED: To provide a charged particle deflector and the like, capable of achieving high reliability and reducing power consumption.SOLUTION: In a charged particle deflector of the present embodiment, charged particle beams travel through the inside of a vacuum duct. The vacuum duct is installed between a first magnetic pole and a second magnetic pole provided at an iron core in a deflection electromagnet. The vacuum duct is in contact with a first magnetic pole face and a second magnetic pole face facing each other in the first magnetic pole and the second magnetic pole.
