Figure 3
Photograph of the sample stage and the available degrees of freedom of the sample. The hexapod performs three translations (x,y,z) and rotations about those axes for sample alignment. The φ-stage rotates the sample about the surface normal. The incidence angle on the sample is controlled by the θ-stage. The entire height of the assembly is adjusted with hstage so that the rotation center of the θ-stage coincides with the rotation center of the diffractometer. For scale, the sample cell is two inches high. |
