6.3 The Mirror_elliptic McXtrace 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.

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. |

R0 |

Reflectivity of mirror (mostly relevant for debugging, when coating=””) |
