Diffraction imaging using x-ray topography ͑XRT͒ and x-ray multiple diffraction ͑XRMD͒ provide valuable tools for examining the growth defects in crystals and the distributions from ideal lattice symmetry ͑microcrystallography͒. The topographic x-ray multiple diffraction microprobe ͑TMDM͒ combines the complementary aspects of both techniques enabling XRT and XRMD studies within the same instrument providing a useful resource for the structural characterization of materials that are not very
