Laue Monochromator
------------------
Bending of a single crystal Laue Monochromator
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Files in ``\examples\withRaycing\03_LaueMono``
This example shows the reflectivity of a bent 200-µm-thick Si111 Laue crystal
at various bending radii and energies. Watch how the band width is growing and
the flux is lowering in going to smaller radii.

Double bent-crystal Laue monochromator (beam cleaner)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This example shows the beam images and rocking curves of a bent 200-µm-thick
Si111 double Laue crystal monochromator (similar to the *beam cleaner*
[Karanfil2004]_) at various bending radii and energies.
.. [Karanfil2004] C. Karanfil, D. Chapman, C. U. Segre and G. Bunker, *A device
for selecting and rejecting X-ray harmonics in synchrotron radiation beams*,
J. Synchrotron Rad. **11** (2004) 393-8.
Beam images at various detuning angles of the second crystal, *R* = 25 m, *E* ~
9 keV. Watch how the energy band becomes split and the flux goes down in going
away from the parallel positioning (*dθ* = 0).
