The Monochromator component

Monochrmator/analyzer crystal (OBSOLETE).

Identification

• Origin: McStas release
• Date: June 16, 1997
• Version: 1.9
• Modification history:

Description

NOTE: This component is obsolete. Use the component Mosaic_anisotropic
instead, which has the same parameters. For a more detailed monochromator
simulation, use the component Single_crystal.

Flat monochromator which uses a small-mosaicity approximation as well as
the approximation vy^2 << vz^2 + vx^2.
Second order scattering is neglected.
For an unrotated monochromator component, the crystal plane lies in the y-z
plane (ie. parallel to the beam).

Input parameters

Parameters in boldface are required; the others are optional.
