The Attenuating_mask 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.

Name	Unit	Description	Default
att_file	".txt"	File that contains the object information. (Default: "W.txt")	"W.txt"
xwidth	m	Horizontal width of the mask. (Default: 1e-1)	1e-1
yheight	m	Vertical height of the mask. (Default: 1e-1)	1e-1
zdepth	m	Thickness of the absorbing mask. (Default: 3e-3)	10e-6
blocks_xwidth	m	Width of the absorbing blocks in the x-direction. (Default: 3e-3)	1e-3
blocks_xdist	m	Distance between absorbing blocks in the x-direction. (Default: 10e-3)	2.5e-3
blocks_yheight	m	Height of the absorbing blocks in the y-direction. (Default: 3e-3)	1e-3
blocks_ydist	m	Distance between absorbing blocks in the y-direction. (Default: 10e-3)	2.5e-2
holed_mask	1	Set to 1 if the mask is a holed grid. (Default: 0)	0
