Hello,
Thanks for the good advice, my example runs without errors now. Right
now I'm trying to create simulation that calculates the energy spectrum
(i.e Neutron Energy vs Neutron Fluence) for a beam of neutrons 20 cm
after interacting with a steel target. I'm not entirely sure which
detector to use in this case, because I am getting slightly confused by
the detector definitions in the manual. Could you help me decide which
detector to use and possibly explain to me how to set it up in a simple
way? I have used a usrbdx, with two adjacent cubes defining the upstream
and downstream of the detector. Since that didn't work, I've tried to
create a usrcoll detector defined by a simple vacuum region.
All in all I think I'm always getting exclusively zero for the fluence
at any energy. I Hope you can help. I feel like I understand a lot
about whats going on, but just not enough.
thanks again,
Jay
