McStas: Attenuating_mask

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

The Attenuating_mask Component

Attenuating_mask

Identification

  • Site:
  • Author: Matteo Busi, Erik B Knudsen
  • Origin: DTU Physics
  • Date: November 2017

Description

This component models a mask of energy dependent attenuation. This consists of a rectangular grid of size
"xwidth*yheight", composed of multiple disks of finite thickness "zdepth" of an attenuating material "att_file",
width "blocks_width" and period "blocks_dist"(i.e. distance between the center of each disk).
If holed_mask mode is turned the model of the component is the opposite, i.e. the mask is composed of an
attenuating slab of finite thickness and of size "xwidth*yheight", with apertures of desired width and period.
