The Monochromator_flat Component

Flat Monochromator crystal with anisotropic mosaic.

Identification

Description

Flat, infinitely thin mosaic crystal, useful as a monochromator or analyzer.
For an unrotated monochromator component, the crystal surface lies in the Y-Z
plane (ie. parallel to the beam).
The mosaic is anisotropic gaussian, with different FWHMs in the Y and Z
directions. The scattering vector is perpendicular to the surface.

Example: Monochromator_flat(zmin=-0.1, zmax=0.1, ymin=-0.1, ymax=0.1, 
          mosaich=30.0, mosaicv=30.0, r0=0.7, Q=1.8734)
