Abstract
A charged particle accelerating apparatus has a vacuum chamber for transporting, accelerating, deflecting or storing charged particles. A layer of a low gas-generating material is placed in the vacuum chamber at a position where radiation generated by deflection of the charged particles are irradiated, the low gas-generating material having properties of generating an amount of gas less than a material constituting the vacuum chamber.
