12 Appendix 3: Optical paths of X-Rays in ARL
EQUINOX 100
The figure describes the X-Ray beam
propagation inside of the enclosure
when the shutter is opened. During this
operation, the enclosure is closed and
door is blocked.
1.
X-Ray source emission. Scattering is emitted in all directions. The tube shield is limiting
the X-Ray.
2.
X-Ray mirror allows to capture a given solid angle from the direct beam, and emits a
narrow focused and monochromatic beam.
3.
Primary crossed slits can shape the incident beam from 0.5 to 0.02 mm.
4.
The anti-scattering knife decreases the diffusion from the slits
5.
The sample is able to diffract the beam according to its atomic structure
6.
The beam stop blocks the direct beam. A proper adjustment of this plate allows to improve
the low angle detection.
