Beamline optics
---------------
The images below are produced by the scripts in
``\examples\withRaycing\02_Balder_BL\``.
The examples show the scans of various optical elements at Balder@MaxIV
beamline. The source is a multipole conventional wiggler.
Diamond filter of varying thickness
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shown are i) intensity downstream of the filter and its energy spectrum and
ii) absorbed power in the filter with its energy spectrum and power density
isolines at 85% and 95% of the maximum.

Bending of collimating mirror
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shown are i) image downstream of the DCM and ii) image at the sample.

Bending of focusing mirror
~~~~~~~~~~~~~~~~~~~~~~~~~~
Shown is the image at the sample position.

Both mirrors (collimating + focusing) at varying pitch angle
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The sagittal radius of the focusing toroid mirror is optimal at 2 mrad pitch
angle.

Scanning of Double Multilayer Monochromator
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This example shows a scan of a double multilayer monochromator – analog of a
double crystal monochromator. On the left is the footprint on the 1st
multilayer. On the right is a transversal image of the exit beam. The two
multilayers are equal and have 40 pairs of 27-Å-thick silicon on 18-Å-thick
tungsten layers on top of a silicon substrate.
