Abstract
A variety of possible schemes of X–ray sources based on Cherenkov like emission mechanisms is considered theoretically. The possibility to increase substantially an angular density of parametric X–ray source under conditions of grazing incidence of emitting relativistic electrons on the re.ecting crystallographic plane of a crystalline target is shown. The growth of Cherenkov X–ray angular density due to modi.cation of the structure of Cherenkov cone in conditions of grazing incidence of an electron beam in the surface of a target is discussed as well as the peculiarities of Cherenkov X–ray generation from relativistic electrons crossing a multilayer nanostructure. The question of relative contributions of parametric X–ray and di.racted bremsstrahlung to total emission yield from relativistic electrons moving in a perfect crystal is elucidated. X–ray generation during multipasses of an electron beam through an internal target in circular accelerator is considered as well.
