The Bragg_crystal_simple Component

Perfect Bragg reflecting slab

Identification

• Author: Jose I. Robledo
• Origin: FaMAF - UNC, Argentina
• Date: February 2016

Description

Rectangle of matter perfectly reflecting the incident X-ray beam
that fulfills Bragg's law for a set of scattering vectors in the
vicinity of the theoretical Q given a d-spacing.
The rectangle is in the x-y plane.

Example: Bragg_crystal_simple( yheight=0.05, xwidth=0.02, DM=3.1356, err_Q= 0.000075, r0=1.0)

Input parameters

Parameters in boldface are required; the others are optional.
