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