McStas: Polycrystal

[ Identification | Description | Input parameters | Output parameters | Links ]

The Polycrystal Component

Release: McXtrace 1.0 Polycrystal made from single crystal-like voxels

Identification

  • Site:
  • Author: Martin Cramer Pedersen (mcpe@nbi.dk)
  • Origin: University of Copenhagen
  • Date: January 2015

Description

The component creates a threedimensional grid of cubic instances of the Single_crystal-component,through
which the rays are propagated. The component relies on a list of possible orientations and stretches of the
initial unit cell and a list correlating each voxel of the polycrystal to an entry in the list of rotations
and stretches.
