10.12 The PolLambda_monitor McStas Component
Polarisation and wavelength sensitive monitor.
Identification
-
Author: Peter Christiansen
-
Origin: Risoe
-
Date: July 2006
Description
A square single monitor that measures the projection of the polarisation along a given normalized m-vector (mx, my, mz) as a function of wavelength.
Example: Pollambda_monitor(Lmin=1, Lmax=20, nL=20, xwidth=0.1, yheight=0.1, npol=11, mx=0, my=1, mz=0, filename="pollambdaMon.data")
Input parameters
Parameters in boldface are required; the others are optional.
