Abstract
It is calculated that simultaneous ultrasonic excitation of the Bonse–Hart monochromator and analyzer leads to the improvement of resolution and increasing of the intensity. It is argued that incoherent ultrasonic field is applicable in similar experiments. Ultrasonic phonon satellites were studied by means of Bonse–Hart channel cut crystal. Strong improvement of contrast with moderate loss of intensity was observed in this case. Double Crystal diffractometer with ultrasonically excited monochromator and analyzer was applied for the ultrasonic phonon satellite research. It was observed for the first time that this “double sound” technique leads to the strong improvement of contrast and simultaneously 60% increasing of the intensity.
