| Summary: | Title screen A novel type of a periodical crystalline target for the generation of coherent X-rays by relativistic electrons is described. The target has been done on the surface of a GaAs crystal plate by means of microlitography. The etched microstructure is a system of about 300 stripes 14 ?m thick, 100 ?m high and the gaps between the stripes are 29 ?m. The measured spectra and orientational dependences of the X-rays emitted at an angle of 19° to the 850 MeV electron beam of the Tomsk synchrotron are discussed. The generated 63 keV radiation consists of parametric X-ray radiation (PXR) and diffracted X-ray transition radiation (DTR). It has been shown that the intensity of the DTR component of the generated X-rays is much more great than that of the PXR Режим доступа: по договору с организацией-держателем ресурса |
