Abstract:
Features of the simultaneous action of longitudinal and transverse ultrasonic vibrations in the quartz crystal on the parameters of reflected X-rays are studied. It is shown that this action results both in the X-ray acoustic conversion effect, which is an increase in the intensity of radiation diffracted by the crystal at the excitation of transverse vibrations with linear polarization, and in the broadening of the rocking curve, which is due to the formation of a standing wave in the crystal at longitudinal vibrations. It is demonstrated for the first time that several key parameters of X-rays can be simultaneously controlled using a single crystal. Transverse vibrations make it possible to vary the intensity of diffracted radiation, and longitudinal vibrations allow controllable angular rearrangement of the X-ray beam diffracted by the crystal.
