A source that produces a time and energy distribution from the SNS moderator files
Author: G. Granroth
Origin: SNS Project Oak Ridge National Laboratory
Date: July 2004
Produces a time-of-flight spectrum from SNS moderator files
moderator files can be obtained from the SNS website .
IMPORTANT: The output units of this component are N/pulseIMPORTANT: The component needs a FULL PATH to the source input file
(1) the raw moderator files are per Sr. The focusing parameters provide the solid
angle accepted by the guide to remove the Sr dependence from the output. Therefore
the best practice is to set focus_xw and focus_yh to the width and height of the next beam
component, respectively. The dist parameter should then be set as the distance
from the moderator to the first component.
(2) This component works purely by interpolation. Therefore be sure that Emin and
Emax are within the limits of the moderator file
WARNING: This is a contributed Component.
