| Samenvatting: | Title screen The experiment at the Tomsk synchrotron on generation of 27 keV X-rays by 500 MeV electrons in a new type of a periodical crystalline target is presented. The target has been made on the surface of a GaAs crystal plate by means of microlithography. The etched microstructure is a system of about 300 strips, 14 μm thick, 100 μm high and the gaps between the strips are 29 μm. The measured spectra and orientational dependences of the X-rays emitted at a Bragg angle are discussed. The generated radiation consists of parametric X-ray radiation (PXR) and diffracted X-ray transition radiation (DTR). It is shown that the intensity of the DTR component of generated X-rays is much higher than that of the PXR Режим доступа: по договору с организацией-держателем ресурса |
