【 摘 要 】

The detailed data treatment of the experiment performed in MAMI-B microtron with the X-ray camera, taking into account the contribution of both diffracted transition radiation and bremsstrahlung, is presented. The X-ray camera efficiency was additionally considered. The simulated emission pattern in general agrees with the experimental one. However, along the Bragg direction where the influence of the beam size on the emission spatial distribution is most noticeable, a discrepancy between the model and the experiment is observed. Possible reasons of such discrepancy are discussed. (C) 2017 Published by Elsevier B.V.
