Abstract
According to the drift tube linear accelerator of the invention, its acceleration cavity is configured with a center plate and a pair of half cylindrical tubes, wherein the center plate includes a ridge, stems connecting the ridge and drift tube electrodes, and the drift tube electrodes, and wherein the acceleration cavity is configured, as seen in cross section perpendicular to a beam-acceleration center axis, whose inner diameter in X-direction that is perpendicular to a central axis in planar direction in which the stem of the center plate extends and that is passing through the beam-acceleration center axis, is longer than whose inner diameter in Y-direction parallel to the central axis in planar direction.
