Radiation of a point charge uniformly moving along the axis of the
circular disc-loaded waveguide    [PDF]

V. A. Berezhnoy, V. N. Kurdyumov

The space-charge distribution of the electromagnetic field excited by point charge moving with a constant velocity on the axis of the circular disc-loaded waveguide was analyzed. The energy losses per structure period numerically were calculated. With increasing charge energy main features of the waveguide modes reach some finite values and, so way, define the limit radiation spectrum. The saturation of the amplitudes of modes (which belongs to the lower part of the limit spectrum) was observed. The analytical techniques and results of calculations were discussed with the use of translation symmetry and the problems that should be noticed were pointed out.
