Description
Some years ago parametric X-ray radiation (PXR) was suggested as a good tool for bunch diagnostic[1], and recently this method was confirmed experimentally[2]. In the theory of PXR there exist two main approaches, kinematic and dynamical ones. The dynamical theory of PXR for divergent beams was suggested in paper[3]. In this article the Gaussian distribution was used to describe the divergence of the electron beam. This supposition can be considered only as approximate one; for more physically appropriate description should be used[4].In this article we continue to construct the kinematic theory of PXR for composite bunches, consisting of two fractions of charged particles with different charges and distributions. The results coincide with our last ones for PXR for composite bunches in case there is no any divergence[5]. We suppose the scedastic distribution of the charged particles in the composite beam and discuss the possibility to get the information of the structure, the divergence, and ionic composition of the bunch with help of PXR.
