Typical parameters of electron bunches available now in undulator X-ray FELs enable generation of induced radiation in crystal-based X-ray VFEL. An important peculiarity of an undulator X-ray FEL is electron bunch spatial modulation with the period equal to the wavelength of the produced radiation. Therefore, XFEL can be considered as a modulator of electron bunch density. As a result a facility combining an undulator, which produced a modulated beam, and a crystal, on which the modulated beam is incident, can be considered to be similar to klystron, which is a well-known source for microwaves emission. Use of pre-modulated beams enables to generate and observe superradiation and induced radiation in a crystal-based X-ray VFEL.
