On the problem of application of diffracted transition radiation for indication of relativistic electron beam parameters [PDF]
Journal of Instrumentation, 2020 The diffracted transition radiation (DTR) produced by a beam of relativistic electrons traversing a thin single-crystal plate in the Laue scattering geometry is considered. We have obtained the expression describing the angular density of the DTR for the case when the path length of the electron in the target is far less than the extinction length of X-
