(a) Five-axis motorized sample stage. From bottom to top: X translation stage, rotation stage, xy translation stage and z-translation stage [xyz-axes are defined with respect to beam direction in Fig. 2(b)]. The DAC is mounted on the topmost stage. (b) For translational positioning of the DAC, electronic loop for automated x–z scanning of the DAC. The x–z scanning algorithm is displayed in the inset on the left. (c) For centering the DAC at the center of rotaion of the goniometer, the DAC is rotated. The x-position of the DAC (xDAC) as a function of rotation angle is shown at the top. The rotation-induced displacement of the DAC () as a function of angle is shown at the bottom. |
