Abstract: | The angular distributions of the intensity of transition radiation from a bunch of relativistic electrons entering a dihedral
angle between two conducting planes have been measured in a millimeter wavelength range. A microtron with a particle energy
of 7.4 MeV is used as a source of electrons. The effect of the particle injection direction and the magnitude of the dihedral
angle on the angular distribution of the radiation intensity has been analyzed. The measurements show that the character of
the distribution of radiation from a charge entering the dihedral angle significantly differs from that for a charge escaping
the angle. A comparatively small change in the magnitude of the dihedral angle can lead to qualitative changes in the angular
distribution of radiation from a charge entering the dihedral angle. |
