(a) Typical transmission geometry for X-ray diffraction of a tantalum single crystal under shock loading. The crystal and sample coordinate systems coincide here. φ is the acute angle between the incident beam and loading direction (L); [\alpha_{i}] (i = 1, 2) denote the angles between the loading direction and diffraction planes ([\bar{1}\bar{1}2]), colored in blue and red for unshocked (U) or shocked (S) portions, respectively. (b) Projection screen or area detector. O is the origin of the detector coordinate system, the intersection of the incident beam with the screen. OL is the projection of the compression direction. Angles [\gamma_{i}] (i = 1, 2, L) denote the azimuthal angles of the diffraction patterns or OL.
