Ewald's sphere - 2A simple cublic crystal with a lattice constant of a=3Å is analyzed by x-ray diffraction. The crystal is oriented such that the (100) plane is on the surface. An x-ray beam penetrates with an angle of 30° relative to the surface of the crystal. The detector scans in the (001) plane.
(a) Make a sketch of the experimental setup. Hint: Draw the real space lattice with the lattice points u,v,0 ( 0 means zero) together with the reciprocal space lattice points h,k,0 (0 means zero) by using the same origin of both lattices.
