(a) Ewald sphere representation of diffraction with polychromatic X-rays. N denotes reciprocal space nodes, which are intercepted by the Ewald spheres of two representative wavelengths ( and ). O is the origin of the reciprocal space. (b) Representative reciprocal space nodes during shock compression at 15 ps. U: unshocked; S: shocked; piston velocity: 0.2 km s−1; no edge release. |
