Direct imaging of travelling Rayleigh waves by stroboscopic X-ray topography
Abstract
The first experiments successfully exploiting the time structure and single bunch mode of operation of the Daresbury Synchrotron Source are reported. Rayleigh waves travelling on the surface of a piezoelectric crystal have been imaged by stroboscopic X-ray topography, and interactions between the Rayleigh waves and microscopic crystalline defects have been observed which provide new insights into the factors which affect surface acoustic wave device operation. The potential of this novel technique for the study of periodic phenomena in crystals has been demonstrated.
