Modification of ViewModerator4 component written by S. Ansell in 2015
Tested with McStas 2.0 and 2.2 (Windows)
Date: February 2016
Version: 1st Draft
Produces a neutron distribution at the ISIS TS1 or TS2 beamline shutter front face (or corresponding moderator) position.
The Face argument determines which TS1 or TS2 beamline is to be sampled by using corresponding Etable file.
Neutrons are created having a range of energies determined by the E0 and E1 arguments.
Trajectories are produced such that they pass through the shutter front face (RECOMENDED) or moderator face (defined by
xw and yh) and a focusing rectangle (defined by focus_xw, focus_yh and dist).
WARNING: This is a contributed Component.
Parameters in boldface are required;
the others are optional.
