McStas: Mirror_Elliptic Component

[ Identification | Description | Input parameters | Output parameters | Links ]

The Mirror_Elliptic Component

Elliptical mirror.

Identification

  • Author: Sylvain Desert
  • Origin: LLB
  • Date: 2007
  • Version:(Unknown)
  • Modification history:
    • E. Farhi, uniformize parameter names (Jul 2008)

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)


WARNING: This is a contributed Component.

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 [m] focal length 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
