Determining Source Directionality from a Scattering Based Neutron Detector System

Three-dimensional directional resolve of neutrons over a wide energy range has proven to be a grand challenge. Various attempts to solve the problem, including neutron cameras and proton recoil based detectors have been met with limited success, with costs in efficiency as well as dimensional and field of view restrictions. To achieve true three dimensional directional resolution, empirical data and Monte Carlo N-Particle Transport Code (MCNP) modeling were used to explore response of a volumetrically sensitive scattering based system to a Cf source of varying angular orientation, then compared through three dimensional cross correlation analysis.
