Figure 12
Picture of two models of the six-axis piezo positioners used for aligning the crystals. For both models shown in (a) and (b), the first five motors are identical. From the bottom up these are: two horizontal linear motors (X, Z), a vertical motor (Y), a rotation around the vertical axis (β), and a tilt (α). The top motor (γ) is a rotary motor in (a) and a tilt in (b). (a) is used as positioner A and C, while (b) is used as positioner B (Appendices C1.1 and C1.2). |
