Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The prospect of creation of the X-ray source with tunable wavelength on the base of a middle energy accelerator and mosaic crystals are analyzed. It is proved, that due to the contribution of diffracted bremsstrahlung, the mosaic crystals provide the essentially greater yield of hard radiation (w ≥ 20 keV), than perfect crystals. It is shown, that using a traditional scheme with one crystal for X-ray generation isn't acceptable for medicine applications. Double-crystal scheme is offered and analyzed, in which one crystal is located on the electrons beam, and another is used for monochromatization and parallel moving of the X-ray beam. It provides suppression of background bremsstrahlung, and there is no need to move the object when change the photons energy. |
