The Mirror_elliptic Component

Idealized elliptic mirror.

Identification

• Author: Erik Knudsen
• Origin: Risoe
• Date: Feb 11, 2010

Description

Takes a reflectivity as input and reflects rays in a ideal geometry
elliptic mirror.
The mirror is positioned such that the a-axis of the mirror ellipsoid is on the
x-axis, the b-axis is along the y-axis and the c is along the z-axis.
The reference point of the mirror is the ellipsoid centre, offset by one
half-axis along the y-axis (See the component manual for a drawing).
This means that to position the mirror correctly,
the user positions the ellipsoid governing the mirror shape, not the mirror itself.

Example: Mirror_elliptic( length=150e-3, width=150e-3, x_a=1.025, y_b=1.025, z_c=1.025)

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
x_a	m	1st short half axis (along x). Commonly set to zero, which really implies infinite value, so crystal is an elliptic cylinder.	0
y_b	m	2nd short half axis (along y), which is also the presumed near-normal direction, reflection near the y-z plane.	1.0
z_c	m	long half axis (along z). Commonly a=0. b=c, which creates a circular cylindrical surface.	1.0
zdepth	m	Depth (length) of the mirror along Z.	0.2
xwidth	m	Width of the mirror along X.	0.2
R0	1	Reflectivity of mirror (mostly relevant for debugging, when coating="")	1
coating	str	Datafile containing either mirror material constants or reflectivity numbers.	"Be.txt"
length	m	alternate name for zdepth (obsolete)	0
width	m	alternate name for xwidth (obsolete)	0
radius	m	Spherical radius, Sets x_a=y_b=z_c=radius	0
