Application of the angular distribution of the diffracted transition radiation in a thin single-crystal target for determination of the divergence of the relativistic electron beam

In the present work the expression describing the transition radiation generated by a relativistic electron beam crossing a thin single crystal plate is derived and the influence of the beam divergence on the radiation angular density is investigated. A computer program, which allows to determinate the relativistic electron beam divergenceby the diffracted transition radiation angular density is created.
