The driving range of the 2θ arm is ±120°. Experiments can be performed using Laue (transmission, back-reflection) and Bragg geometries. Topographic images can be obtained by driving the stage.

You can nondestructively observe the inner microstructure of single crystals. Silicon crystals with thicknesses less than 3 mm can be used in experiments.

You can precisely align the stages about the sample. LabVIEW programs (see Figure 3) are used for topography experiments.

In experiments, the imaging plate reader, darkroom, and optical microscope can all be used.


Experimental processing

1. The incident beam can be adjusted to any size by using the slit.

2. Attach the sample to the stage and use the ionization chamber to align the stages.

3. Set the imaging plate on the 2θ arm and collect diffraction patterns.

4. Insert a high-resolution X-ray film at a specific diffraction spot and observed the microstructure using the microscope.
