4.8.2 Mount and Align the Beam Stop
The beam stop is mounted to restrict the main
beam’s path (divergence).
An un-attenuated beam path may saturate the
detector and prolonged exposure to main beam
intensities may damage the detector.
To Mount the beam stop:
1. Move the 2-theta drive to 60°.
2. Insert the locking T-nut into the goniometer
track (see Figure 4.25).

3. Fasten the beam stop assembly to the goni-
ometer (see Figure 4.26).
3.1 Use the mounting pin to position the
beam stop assembly.
3.2 Insert and tighten the mounting screw.
4. Mount the beam stop in one of the following
positions using the “D” screws in Figure
4.26.
A = 435 mm diameter measuring circle
B = 500 mm diameter measuring circle
C = 600 mm diameter measuring circle

5. Slowly move 2-theta to 0°, checking that the
beam stop does not collide with the anti-
scatter optics of the detector.
6. Adjust the beam stop as necessary to avoid
a collision with the detector optics.
7. Raise 2-theta back to 60°.
8. Check that collision limits are set in the soft-
ware.
