摘要： An RF accelerating cavity includes: a housing having an inner peripheral surface in a tubular shape and conductivity at least on a surface; and accelerating cells inside the housing and each made of a dielectric including, at a central part, an opening through which a charged particle passes. The housing includes a cylindrical barrel portion, with end plates at both ends. The accelerating cells are disposed between the end plates. Each accelerating cell includes: a cylindrical barrel portion having a diameter smaller than an inner diameter of the cylindrical barrel portion of the housing; and a circular disk portion provided inside the cylindrical barrel portion to be fixed to the cylindrical barrel portion, and disposed such that a plate surface is orthogonal to the passing axis of a charged particle, and provided with the opening.

摘要： An accelerating cavity includes an electrically conductive cylindrical housing and a plurality of cells that are made of a dielectric material and have openings in respective central portions of the cells through which charged particles are allowed to pass. The cells are arranged inside the housing while being aligned in the axial direction of the central axis of the housing, and sandwiched by the housing in the axial direction of the central axis to be immobilized. The housing has grooves provided on portions thereof that support the respective cells and each having a depth that is one fourth of the wavelength of radio frequency waves for the acceleration mode that propagate through the cells.
