Geometry of the GIXD set-up. The incident beam forms an angle αi with the sample surface and the diffracted beam is recorded by a planar CCD detector at a distance L from the beam incidence point. αf and 2θ indicate the out-of-plane and in-plane diffraction angles, respectively, 2ΘB is the Bragg angle, ψ is the polar angle and X, Y and Z are the coordinates of the laboratory reference frame. |
