Coherent X-radiation along the velocity of a relativistic electron in a bounded periodic multilayer medium

In the present work a theory of the coherent X-radiation generated by the relativistic electron crossing an artificial periodic layered structure in Laue scattering geometry is built. The expressions are derived for spectral-angular distribution of the radiation in direction of the particle velocity...

Description
Summary:In the present work a theory of the coherent X-radiation generated by the relativistic electron crossing an artificial periodic layered structure in Laue scattering geometry is built. The expressions are derived for spectral-angular distribution of the radiation in direction of the particle velocity. The comparative analysis of the spectral-angular density of the radiation is carried out for an artificial periodic structure and a single crystal in similar conditions. It is shown, that the spectral peak of the parametric X-radiation in the artificial periodic layered structure in the forward direction (FPXR) will be considerably wider than the one in a single crystal target which can make its experimental detection and investigation appreciably easier.
