The Source_flat Component

A circular neutron source with flat energy spectrum and arbitrary flux

Identification

Description

The routine is a circular neutron source, which aims at a square target
centered at the beam (in order to improve MC-acceptance rate).  The angular
divergence is then given by the dimensions of the target. 
The neutron energy is uniformly distributed between E0-dE and E0+dE.

Example: Source_flat(radius=0.1, dist=2, xw=.1, yh=.1, E0=14, dE=2)

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
radius m Radius of circle in (x,y,0) plane where neutrons are generated.  
dist m Distance to target along z axis.  
xw m Width(x) of target  
yh m Height(y) of target  
E0 meV Mean energy of neutrons.  
dE meV Energy spread of neutrons.
