McStas: Mirror_Elliptic

[ Identification | Description | Input parameters | Links ]

The Mirror_Elliptic Component

Elliptical mirror.

Identification

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.
