MCNPX Results

A simulation was done using MCNPX to see how neutron scattering impacts asymmetry measurements. The setup is shown below. Neutrons were created inside a bottle of D2O and given an initial direction towards the 0 degree detector. The size of the target and detectors are the actual size used in the experiment. The distance between the target and each detector is 1 meter.
