12.6 The Attenuating_mask McXtrace Component
Attenuating_mask
Identification
-
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.
Input parameters
Parameters in boldface are required; the others are optional.
