Abstract
The time modulation of the X-ray beam diffracted from a LiNbO3 crystal was observed when the surface acoustic wave (SAW) was excited on it by the piezoelectric effect. Since the SAW device vibrated with a frequency of 14.26 MHz, the X-ray intensity changed sinusoidally with a period of 70 nanoseconds. It is suggested that the present method can be used as a high speed X-ray chopper or shutter.Keywords
