McXtrace: Abs_objects

[ Identification | Description | Input parameters | Links ]

The Abs_objects Component

Blocks of attenuating material in off format

Identification

  • Site:
  • Author: Erik Knudsen
  • Origin: DTU Physics
  • Date: Jan 24, 2011

Description

This component is a model of 1 or more off-shaped blocks attenuating the x-ray beam.
Which shapes are present and their relative positions are described in a file of the follwing format:
#objects
Material-filename  OFF-filename x y z xwidth yheight zdepth
...

An example is;
2
Be.txt  cube.off  0 0.01 0    0 0 0
Rh.txt  chess.off 0 -0.01 0   0 0 0

A xwidth etc of zero means use whatever dimensions are in the off/ply file.
If xwidth (or yheight or zdepth) is nonzero, the component tries to scale the
object to fill that dimension. This is an experimental option.

Input parameters

Parameters in boldface are required; the others are optional.
NameUnitDescriptionDefault
refraction Flag to enable refraction at interfaces.1
