The Mon_2foc component

Double bent monochromator with multiple slabs

Identification

• Author: PL
• Origin: Uni. Gottingen (Germany)
• Date: Feb. 12,1999
• Version: 1.0

Description

Double bent 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).

Added double bent feature by: Peter Link Feb. 12,1999
corrected bug in rotation of v-coords: Peter Link Sep. 24. 1999
