McStas: Filter_graphite

[ Identification | Description | Input parameters | Links ]

The Filter_graphite Component

Pyrolytic graphite filter (analytical model)

Identification

Description

ESCRIPTION

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, length=1.0)

Input parameters
