Description

Models an elliptical mirror. The reflectivity profile is given by a 2-column reflectivity free
text file with format [q(Angs-1) R(0-1)]. The component is centered on the ellipse.

Example:  Mirror_Elliptic(reflect="supermirror_m3.rfl", focus=6.6e-4,
interfocus = 8.2, yheight = 0.0002, zmin=-3.24, zmax=-1.49)

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
reflect	q(Angs-1) R(0-1)	(str) Reflectivity file name. Format	0
focus	m	focal length (m)	6.6e-4
interfocus	m	Distance between the two elliptical focal points	8.2
yheight	m	height of the mirror	2e-4
zmin	m	z-axis coordinate of ellipse start	0
zmax	m	z-axis coordinate of ellipse end	0
R0	1	Low-angle reflectivity	0.99
Qc	AA-1	Critical scattering vector	0.0219
alpha	AA	Slope of reflectivity	6.07
m	1	m-value of material. Zero means completely absorbing.	1.0
W	AA-1	Width of supermirror cut-off	0.003
