Application of ultrasound for the simultaneous improvement intensity and resolution of the Bonse-Hart diffractometer
Original language description
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.

Použití ultrazvuku pro zvýšení světelnosti a rozlišení difraktometru typu Bonse-Hart
Czech description
Jak bylo předpovězeno a spočítáno, buzením fononových satelitů pomocí vysokofrekvenčních ultrazvukových kmitů lze zvýšit rozlišení a světelnost dvoukrystalového difraktometru s monochromátorem a analyzátorem typu Bonse-Hart. Poprvé bylo pozorováno, že použití této metody vede ke značnému zvýšení kontrastu a také světelnosti difraktometru až o 60 %.
