The ViewModISISver1 Component

Modification of ViewModerator4 component written by S. Ansell in 2015 G. Skoro Tested with McStas 2.0 and 2.2 (Windows)

Identification

Description

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 
modXsize and modZsize) and a focusing rectangle (defined by xw, yh and dist).

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
E0 meV Lower edge of energy distribution  
E1 meV Upper edge of energy distribution  
tally - =8.4, modPosition=1, modXsize=0.196, modZsize = 0.12, xw = 0.04, yh = 0.094, dist = 0.5) LET simulation. modPosition=1 so initial surface is at front face of shutter insert. (IMPORTANT) If modPosition=1, the modXsize and modZsize values are obsolete. The dimensions of initial surface are automatically calculated using "RDUM" values in Let_timeTest_155.mcstas file. In this example, xw and yh are arbitrary chosen to be identical to the shutter opening dimension.  
modPosition - Defines the initial surface for neutron distribution production Possible values = 0 or 1 0 = "moderator"; 1 (RECOMENDED) = front face of shutter insert  
modXsize m Moderator width  
modZsize m Moderator height  
xw m Width of focusing rectangle  
yh m Height of focusing rectangle  
dist m Distance from source surface to the focusing rectangle
