The Mirror_elliptic Component

Idealized elliptic mirror.

Identification

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

Description

Takes a reflectivity (default=1) 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.

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
length	m	z depth (length) of the crystal.	0.05
width	m	x width of the crystal.	0.02
R0	1	Reflectivity of mirror.	1
coating	str	Datafile containing either mirror material constants or reflectivity numbers.	""
