Abstract :
Ag- and Au-diffusion swept synthetic quartz samples as thick as 10 mm along the [202¯0] direction were characterized by synchrotron radiation topography at a superconducting vertical wiggler beamline of Photon Factory. The high resolution topographic image allows the visualization of the Ag (Au) diffusion paths along the Z-direction. The stereographic pair topographs can ben used to reproduce the 3-dimensional configuration of the dislocation network. Based on the diffracted and direct (transmitted) images of swept and unswept quartz some new hypotheses concerning the etch-channel suppression mechanism are presented
