The Filter_graphite Component

Pyrolytic graphite filter (analytical model)

Identification

• Author: Thomas C Hansen
• Origin: ILL
• Date: 07 March 2000
• Version: 1.13

Description

This rectangular pyrolytic graphite filter uses an analytical model
with linear interpolation on the neutron wavelength
This type of filter is e.g. used to supress higher harmonics, such as
the 1.2 AA contribution to the 2.4 AA obtained by a highly oriented
pyrolytic graphite (HOPG) monochromator.

Example: Filter_graphite(xmin=-.05, xmax=.05, ymin=-.05, ymax=.05, len=1.0)

WARNING: This is a contributed Component.

Input parameters

Parameters in boldface are required; the others are optional.

xmin	-0.16	[m] Lower x bound
xmax	0.16	[m] Upper x bound
ymin	-0.16	[m] Lower y bound
ymax	0.16	[m] Upper y bound
len	0.05	[m] Thickness of graphite plate
