The Filter Component

Block of an attenuating material

Identification

Description

A chunk of attenuating material. Attenuation is computed through
the effective length travelled within the material.
No scattering is modelled at present.

Filter shape may be a cylinder, a sphere, a box or any other shape.
box/plate:       xwidth x yheight x zdepth
cylinder:        radius x yheight (along Y axis)
sphere:          radius
any shape:       geometry=OFF/PLY_file

Example: Filter(material_datafile="Ge.txt",
geometry="wire.ply",xwidth=0.02,yheight=0,zdepth=0)

Input parameters

Parameters in boldface are required; the others are optional.
