研究了用超相对论电子束产生参量X射线辐射的新结构。光束沿着周期性多层结构（超晶格）的外表面传播，光子在掠入射衍射条件下发射。计算这种情况下的PXR光谱强度。结果表明，这种特定的配置的电子束和目标辐射器可以用于PXR一代在存储环。它可以在很窄的光谱范围内获得频率平滑调谐、光谱强度超过同步辐射强度的单色X射线束。
New configuration for generation of the parametric X-ray radiation (PXR) by an ultrarelativistic electron beam is considered. The beam propagates along the external surface of periodical multilayer structure (superlattice) while the photons are emitted under the condition of grazing incidence diffraction. PXR spectral intensity is calculated for this case. It is shown that this specific configuration of the electron beam and target radiator can be used for the PXR generation in a storage ring. It can allow one to obtain the monochromatic X-ray beams with the smoothly tuned frequency and the spectral intensity exceeding intensity of the synchrotron radiation in the narrow spectral ranges.
