McStas: Mirror_Parabolic

[ Identification | Description | Input parameters | Links ]

The Mirror_Parabolic Component

Parabolic mirror.

Identification

Description

Models a parabolic mirror. The reflectivity profile is given by a 2-column reflectivity free
text file with format [q(Angs-1) R(0-1)].

Example:  Mirror_Parabolic(reflect="supermirror_m3.rfl", xwidth = 0.05, xshift=0.05,
yheight = 2e-4, focus = 6.6e-4)

Input parameters

Parameters in boldface are required; the others are optional.
