| Streszczenie: | Заглавие с экрана Смоделирован процесс когерентного рассеяния рентгеновского излучения на монокристаллах кварца при наличии температурного градиента или акустического воздействия для падающего пучка с любым спектрально-угловым распределением. Впервые показано, что в зависимости от толщины монокристалла и спектрально-углового распределения первичного пучка интегральная интенсивность отраженного пучка увеличивается больше чем в 20 раз. The process for coherent X-ray scattering on single quartz crystals in the presence of a temperature gradient or acoustic influence has been modeled for incident beam with spectral-angular distribution with I (λ,θ ) intensity. In the conditions of full pumping of X-rays the integral intensity of the reflected beam increases more than 20 times, if the incident beam has relative spectral-angular width greater than 10-4 an increase from 3 to 20 times can be observed when the relative spectral-angular width changes from 10-5 to 10-4, an increase of 2-3 times can be observed when the relative spectral-angular width is less than 10-5 (the case of flat-monochromatic radiation but an increas in 3 times can be reached due to transparecy effect). The spectral-angular width of the transmitting X-ray depends on the width of the researched monocrystall, and the maximal integral intensity of the reflected beam is reached when the width of the monocrystall is μt = 1.
