Influence of the Divergence of the Relativistic Electron Beam on Diffracted Transition Radiation Exited by Them in Monocrystalline Target
The dependence of the angular density and the photons yield of the collimated diffracted transition radiation (DTR) generated in a thin single crystal plate by a beam of relativistic electrons on the beam divergence are studied. The expression describing the DTR angular density averaged by all the rectangular trajectories of electrons in the beam are derived. For the averaging the two-dimensional Gauss distribution was used. The considerable dependence of the angular density of collimated DTR photons on the electron beam divergence is shown. The expression describing the number of collimated DTR photons is obtained. The considerable dependence of the photon number of collimated DTR are shown.
