The Monochromator_flat Component

Flat monochromator crystal simple model. (EXPERIMENTAL)

Identification

Description

Flat, infinitely thin 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).

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)
