The possibility of obtaining parallel X-ray beams and controlling their quantity and distances in a wide range has been experimentally considered. To implement this experiment, a three-crystal scheme was assembled. The first crystal is set to monochromatize an X-ray beam, which provides high resolution. The second quartz crystal with AT - cut is used to obtain parallel X-ray beams with different distances and quantities using the effect of bulk acoustic waves with different frequencies. And the third quartz crystal with asymmetric reflection is used to control the distances of parallel beams in a wide range (from 50 µm to 1 mm). Thus it is shown that, using such a three-crystal scheme, it is possible to obtain any number of parallel X-ray beams and control their distances in wide ranges.
