3. Adjust the yaw “Y” of the 2 DOF. The yaw 
adjustment uses opposing screws. To make 
an adjustment, first loosen the opposing 
screw and then tighten the adjusting screw 
(see Figure 8.2).

4. Re-run the scan and compare the ratio to 
the baseline scan. If the ratio increases, 
continue to adjust in the direction first 
attempted. If the ratio decreases, reverse 
the direction of movement and repeat step 3 
until the maximum ratio is achieved. Use the 
ratio to check the alignment. Intensity of the 
valley alone may vary.
5. Repeat step 3 and step 4 for the roll “Z” of 
the 2 DOF until a ratio of 3.5 to 4.0 is 
achieved. Noticeable separation can be 
seen between the Kα
1
 and Kα
2
 peaks when 
alignment is correct. Save the final scan for 
future reference.
